SLIDE 4 — Introduction

  • Distal radial fractures are the most common fractures managed by orthopaedic surgeons, representing ~15% of all fractures presenting to emergency departments.
  • Two dominant surgical strategies exist for displaced, unstable extra-articular fractures (OTA/AO type A3):
    • Volar Locking Plate (VLP) – internal fixation with a palmar plate
    • External Fixation (EF) – spanning or non-spanning frame fixation
  • Over the past two decades, VLP use has risen dramatically, replacing EF as the preferred technique in many centres worldwide.
  • This shift has been driven primarily by theoretical advantages (stable fixation, early mobilisation) rather than robust Level I evidence.
  • Multiple earlier RCTs and meta-analyses produced conflicting results or were underpowered, leaving the optimal surgical approach uncertain.
  • The trend favouring VLP carries additional costs and is associated with specific hardware-related complications (tendon rupture, plate removal).
  • This study was designed to provide Level I evidence resolving the debate.

SLIDE 5 — Aim & Objectives

Primary Aim: To determine whether external fixation (EF) or volar locking plate (VLP) provides superior functional outcomes in patients with displaced extra-articular distal radial fractures (OTA/AO type A3) at 6 weeks, 3 months, and 1 year postoperatively.
Secondary Objectives:
  • Compare patient-reported pain and disability (QuickDASH, VAS) between the two groups over 1 year
  • Assess radiographic parameters: volar tilt, radial inclination, radial height, ulnar variance
  • Compare range of motion, grip strength, and finger stiffness at each follow-up point
  • Document and compare complication rates and reoperations between groups

SLIDE 6 — Methods & Materials

Study Design & Setting:
  • Design: Multicenter, parallel-group RCT
  • Centres: Haukeland University Hospital & Voss Hospital, Norway
  • Period: 2013–2017
  • Registration: ClinicalTrials.gov (NCT01904084)
  • Ethics: Declaration of Helsinki; ethics committee approved
  • Allocation: Computer-generated 1:1 randomisation with sealed envelopes; stratified by centre and surgeon
  • Blinding: Surgeons unblinded (unavoidable); outcome assessors and statistician blinded
Interventions & Follow-up:
  • Intervention A – VLP: Volar locking plate fixation; early mobilisation from 3–5 days post-op
  • Intervention B – EF: Bridging external fixation (± adjuvant K-wires); frame kept 5–6 weeks then physiotherapy
  • Follow-up: 6 weeks, 3 months, 1 year
  • Radiographs: Standard PA + lateral wrist at each visit (volar tilt, radial height, inclination, ulnar variance)
  • Physiotherapy: Standardised protocol for both groups after hardware removal/early mobilisation

SLIDE 7 — Inclusion & Exclusion Criteria

Inclusion Criteria:
  • Age 18–70 years
  • Isolated unilateral displaced extra-articular distal radial fracture (OTA/AO type A3)
  • Substantial initial displacement OR inadequate closed reduction OR loss of reduction within 2 weeks, defined by at least one of:
    • 10° dorsal angulation of the joint line
    • Ulnar variance of >2 mm
    • Dorsal comminution / loss of intact dorsal cortex
  • Presenting to Haukeland University Hospital or Voss Hospital (2013–2017)
  • Able to provide informed written consent
Exclusion Criteria:
  • Dementia
  • Severe mental illness
  • Open fractures
  • Associated ipsilateral upper-limb injuries
  • Contralateral wrist pathology precluding comparison
  • Polytrauma / multiple injuries
  • Prior significant wrist injury or surgery on the affected side
  • Contraindication to either surgical technique

SLIDE 8 — Statistical Analysis

  • Sample Size: 75 patients per group (150 total) calculated to detect a 10-point difference in PRWHE at 6 weeks with 80% power (α = 0.05), accounting for 10% dropout.
  • Primary Analysis: Mixed-model ANOVA for repeated measures on PROM data (PRWHE, QuickDASH, VAS) to account for within-subject correlation across time points.
  • Continuous Variables: Student's t-test for non-PROM continuous outcomes at individual time points.
  • Categorical Variables: Chi-square (χ²) test for categorical data (e.g., complication rates, reoperation).
  • Analysis Principle: Intention-to-treat (ITT) – patients analysed in the group to which they were originally randomised, regardless of protocol adherence.
  • Missing Data: Handled within the mixed-model framework; patients with at least one follow-up visit were included.
  • Software: SPSS version 26.0 (IBM Corp., Armonk, NY)
  • Significance Level: p < 0.05 (two-tailed) for all comparisons.

SLIDE 9 — Outcome Measures

Primary Outcome: Patient-Rated Wrist/Hand Evaluation (PRWHE) Score – assesses wrist pain and function on a 0–100 scale (0 = no disability); assessed at 6 weeks, 3 months, and 1 year.
Secondary Outcomes:
  • QuickDASH – Shortened DASH (0–100); pain and disability of arm, shoulder and hand
  • VAS Pain – Visual Analogue Scale for pain at rest and during activity (0–10 cm)
  • Range of Motion – Wrist flexion/extension, pronation/supination, radial/ulnar deviation (goniometry)
  • Grip Strength – Jamar dynamometer; reported as % of contralateral side
  • Finger Stiffness – Inability to make a full fist; recorded as present/absent
  • Radiographic Parameters – Volar tilt (°), radial inclination (°), radial height (mm), ulnar variance (mm)
  • Complications & Reoperations – Major (CRPS, deep infection, CTS, suboptimal osteosynthesis, plate removal) and minor (superficial infection, paresthesia, scar problems)

SLIDE 10 — Results (Part A: Patient Flow & Primary Outcome)

Note: Plate removal occurred only in VLP group: 5 patients (7%), p = 0.025

SLIDE 12 — Conclusion

  • Early Recovery Advantage: VLP provides significantly better functional outcomes (PRWHE, QuickDASH, ROM) at 6 weeks, with advantages persisting into 3 months.
  • Equivalence at 1 Year: No significant difference in the primary outcome or most secondary outcomes at 1 year – both techniques deliver similar long-term results.
  • Wrist Extension: VLP maintained a statistically significant advantage in wrist extension at 1 year (64° vs 59°, p = 0.013) – relevant for activities of daily living.
  • Complication Profile: Major complication rates were comparable (VLP 23% vs EF 25%), but plate removal was exclusively a VLP complication (7%, p = 0.025).
  • Clinical Implication: This Level I RCT supports VLP as the preferred technique when early return to function is a priority, but EF remains a valid alternative with similar 1-year outcomes.

SLIDE 13 — Study Limitations

  • Lack of blinding for surgeons and patients (inherent to surgical RCTs) – potential for performance and detection bias.
  • Single-country design (Norway): patient demographics, surgical expertise, and rehabilitation protocols may limit generalisability to other settings.
  • Female predominance (89%): findings may not fully apply to younger male patients or those with higher functional demands.
  • Limited to extra-articular fractures (OTA/AO type A3) only – conclusions cannot be extrapolated to intra-articular or comminuted patterns.
  • Loss to follow-up: 14 patients (9%) did not complete 1-year assessment; ITT used but some bias possible.
  • No formal health-economic analysis: cost comparison between VLP (expensive implant) and EF was not performed.
  • Maximum follow-up 1 year: long-term outcomes (arthritis, tendon rupture, hardware failure) remain unknown.
  • Variability in EF technique: adjuvant K-wires were at surgeon discretion, introducing heterogeneity in the EF arm.
  • Plate removal in 7% of VLP patients represents an underappreciated added cost and complication.

Time period of study?

The study was conducted from 2013 to 2017 (patient recruitment period).
  • Recruitment: 2013–2017 at Haukeland University Hospital and Voss Hospital, Norway
  • Follow-up per patient: up to 1 year after surgery
  • Paper published: March 3, 2021
So the total study duration (recruitment + last patient's 1-year follow-up) ran approximately 2013 to 2018, with a gap of ~3 years before publication in 2021.

what is prwhe

PRWHE – Patient-Rated Wrist/Hand Evaluation

Full name: Patient-Rated Wrist and Hand Evaluation

What it is

A self-reported questionnaire that measures wrist pain and disability from the patient's own perspective. Developed by MacDermid et al. (1998).

Structure

It has 2 subscales with 15 questions total:
SubscaleQuestionsWhat it measures
Pain5 itemsPain at rest, with specific activities, at its worst, usual pain, etc.
Function10 itemsSpecific activities (6 items) + usual activities (4 items)

Scoring

  • Each item scored 0–10
  • Pain subscale: sum of 5 items (max 50)
  • Function subscale: sum of 10 items ÷ 2 (max 50)
  • Total score = Pain + Function = 0 to 100
  • 0 = no pain / no disability
  • 100 = worst possible pain and disability

Why it was used in this study

  • It is the gold standard patient-reported outcome for wrist fractures
  • More sensitive and specific for wrist conditions than general upper limb tools
  • Minimum clinically important difference (MCID) = ~14 points
  • Validated, reliable, and widely used in distal radius fracture research

In plain terms

It simply asks the patient: "How much does your wrist hurt and how much does it stop you from doing things?" — and turns the answers into a number out of 100.

What does QuickDASH measure and how does it differ from PRWHE?0,11?

QuickDASH – What It Measures

Full name: Quick Disabilities of the Arm, Shoulder and Hand
A self-reported questionnaire measuring physical function and symptoms in people with any musculoskeletal disorder of the upper limb. It is a shortened version of the original 30-item DASH questionnaire.

Structure

  • 11 items only
  • Covers: difficulty with physical tasks, severity of pain, tingling, weakness, stiffness, and impact on social/work activities
  • Each item scored 1–5 (1 = no difficulty, 5 = unable to do)

Scoring Formula

(Sum of all 11 responses − 11) ÷ 0.44 = score out of 100
  • 0 = no disability
  • 100 = complete disability

Role in this studySecondary outcomePrimary outcome

Why both were used in this study

  • PRWHE was chosen as the primary outcome because it is wrist-specific and more sensitive to changes after distal radius fractures
  • QuickDASH was included as a secondary outcome to allow comparison with other upper limb studies and broaden generalisability
  • Both tools showed the same pattern of results in this paper – VLP superior at 6 weeks and 3 months, no significant difference at 1 year – which strengthens the conclusions

In plain terms

  • PRWHE = "How is YOUR wrist?" (focused)
  • QuickDASH = "How is your whole arm?" (broad)

Here are detailed presenter's notes for Slides 8 through 11, written in a natural speaking style.

SLIDE 8 — Statistical Analysis

Presenter's Notes

"Before we look at the results, it's worth understanding how the authors analysed their data, because the choices made here directly affect how we interpret the findings.
The trial was powered to detect a 10-point difference in PRWHE scores at 6 weeks — this is close to the minimum clinically important difference of 14 points, so the study was designed to pick up a meaningful clinical change, not just a statistical one. They calculated they needed 75 patients per group, accounting for a 10% dropout — which is why they enrolled 156 patients total.
For the primary analysis, they used a mixed-model ANOVA for repeated measures. This is important — it means rather than analysing each time point in isolation, the model looks at all three time points together (6 weeks, 3 months, 1 year) while accounting for the fact that the same patient is measured multiple times. This approach is more statistically appropriate and handles missing data better than a simple t-test at each visit.
For straightforward comparisons between groups at a single time point — things like grip strength or range of motion — they used the Student's t-test. For yes/no type data like complication rates and reoperations, they used the chi-square test.
Critically, all analyses followed the intention-to-treat principle. This means that if a patient was randomised to EF but ended up getting a VLP for any reason, they were still analysed in the EF group. This is the gold standard for RCT analysis because it reflects real-world decision-making and avoids overestimating treatment effects.
The significance threshold was set at p < 0.05, and all tests were two-tailed. Software used was SPSS version 26."

SLIDE 9 — Outcome Measures

Presenter's Notes

"This slide covers what was actually measured in this trial — and it is important because outcome selection determines what conclusions you can and cannot draw.
The primary outcome was the PRWHE — the Patient-Rated Wrist and Hand Evaluation — a validated 15-item questionnaire scored 0 to 100, where zero means no pain and no disability. It was chosen because it is the most sensitive and wrist-specific patient-reported tool available. Every conclusion about which treatment is 'better' in this paper is ultimately anchored to this score.
The secondary outcomes cover a wide range of domains. Let me highlight a few:
QuickDASH captures broader upper limb function across 11 items and was included to allow comparison with other studies. It showed the same trend as PRWHE throughout.
VAS for pain was recorded both at rest and during activity — the distinction matters, because resting pain and functional pain often behave differently after surgery.
Range of motion was measured with a goniometer at every visit — flexion, extension, pronation, supination, radial and ulnar deviation — and all values were expressed as a percentage of the uninjured contralateral side. This is a clean way to account for individual baseline differences.
Grip strength was measured with the Jamar dynamometer — the most widely validated grip measurement tool — again as a percentage of the contralateral side.
Radiographic parameters — volar tilt, radial height, radial inclination, and ulnar variance — were measured on standard PA and lateral wrist radiographs at every visit. This allows us to see whether clinical outcomes correlate with anatomical restoration.
Complications were carefully categorised as major or minor. Major complications included CRPS, deep infection, carpal tunnel syndrome, suboptimal osteosynthesis requiring reoperation, and plate removal. Minor ones included superficial infection, scar tissue problems, and paresthesia. This distinction is clinically meaningful — major complications directly impact patient management."

Presenter's Notes

"Now to the results. Let's start with who was actually in the study and what happened to the primary outcome.
156 patients were enrolled — 69 allocated to VLP and 73 to EF. A small number had crossovers and dropouts, but 142 patients — 91% — completed the full one-year follow-up. That is an excellent retention rate for a surgical RCT, and it gives us good confidence in the 1-year data.
The cohort was predominantly female — 89% — with a mean age of 56 years. This is expected, because displaced distal radial fractures in this age group are largely low-energy fragility fractures in postmenopausal women with osteoporosis. Keep this demographic in mind when thinking about generalisability.
Now, the primary outcome — PRWHE at 6 weeks:
  • VLP group had a median score of 27
  • EF group had a median score of 44
  • That is a 17-point difference, which is statistically significant at p < 0.001 and also exceeds the minimum clinically important difference of 14 points.
So at 6 weeks, VLP patients were reporting meaningfully less pain and disability than EF patients. This is not a subtle statistical finding — it represents a real difference in how patients are feeling and functioning in the early postoperative period.
However — and this is the key message of the paper — at 3 months the difference was no longer significant (p = 0.069), and at 1 year it was clearly not significant (p = 0.233). The two groups converged. EF patients caught up.
So the story of this primary outcome is: VLP gives you a faster start, but both groups end up in the same place at 1 year."

SLIDE 11 — Results Part B: Secondary & Functional Outcomes

Presenter's Notes

"The secondary outcomes largely tell the same story as the primary — but there are a few important nuances worth highlighting.
QuickDASH mirrored the PRWHE pattern perfectly. VLP was significantly better at 6 weeks (27 vs 43, p < 0.001) and at 3 months (p = 0.023), but the groups were equivalent at 1 year. This consistency between two independent tools strengthens our confidence in the finding.
Range of motion is where things get interesting. At 6 weeks, the VLP group had dramatically better wrist extension — 43 degrees versus just 3 degrees in the EF group. That near-zero extension in the EF group is expected because the external fixator physically bridges the wrist joint in a neutral or slightly flexed position, preventing extension. Once the fixator comes off, EF patients recover rapidly — but they never quite catch up in extension.
In fact, wrist extension at 1 year remained significantly better in the VLP group — 64° versus 59°, p = 0.013. This is the one outcome where VLP maintained a statistically significant advantage at final follow-up. Whether 5 degrees of wrist extension makes a meaningful real-world difference is debatable, but it is worth noting.
Flexion and supination differences disappeared by 1 year — both groups essentially recovered fully.
Pain during activity on VAS also favoured VLP at 3 months and 1 year — consistent with slightly better functional recovery.
Complications — this is a critical slide for shared decision-making. Major complication rates were statistically identical — 23% in VLP versus 25% in EF, p = 0.83. However, look at plate removal — 5 patients in the VLP group (7%) required their plate removed, versus zero in the EF group, and this was statistically significant (p = 0.025). Plate removal means an additional surgical procedure, additional anaesthetic risk, and additional cost.
So while VLP has no higher overall complication burden, it does carry a unique hardware-specific complication that EF does not. This should be part of the conversation with patients when choosing between the two techniques."

keep the presenter notes short

Here are the short presenter's notes for Slides 8–11.

SLIDE 8 — Statistical Analysis

"The study was powered to detect a 10-point difference in PRWHE — close to the clinically important threshold. A mixed-model ANOVA was used for repeated measures across all three time points, which is more appropriate than running separate t-tests at each visit. All analyses followed the intention-to-treat principle — patients were analysed in the group they were randomised to, regardless of what actually happened. Significance was set at p < 0.05."

SLIDE 9 — Outcome Measures

"The primary outcome, PRWHE, was chosen because it is the most wrist-specific validated tool available. Secondary outcomes were broad — covering pain, function, range of motion, grip strength, radiographs, and complications. ROM was always expressed as a percentage of the uninjured side to account for individual differences. Complications were split into major and minor — this distinction matters because major complications directly changed patient management."

SLIDE 10 — Results Part A

"156 patients enrolled, 142 completed 1 year — a 91% retention rate, which is excellent for a surgical RCT. The cohort was 89% female, mean age 56 — typical for this fracture type.
At 6 weeks, VLP was significantly better — PRWHE 27 versus 44, a 17-point difference that exceeds the clinically important threshold. However, this advantage disappeared by 3 months and was clearly gone at 1 year. Both groups ended up in the same place — VLP just got there faster."

SLIDE 11 — Results Part B

"QuickDASH mirrored the PRWHE findings throughout — consistent across both tools. Wrist extension at 6 weeks was striking — 43° in VLP versus just 3° in EF, because the fixator physically blocks extension. Importantly, wrist extension remained significantly better in VLP even at 1 year — 64° vs 59°, p = 0.013 — the only outcome where VLP held a lasting advantage.
On complications — overall major complication rates were equal. But plate removal occurred in 7% of VLP patients and zero in EF, p = 0.025. That means an extra operation, extra anaesthetic, extra cost — something patients should be told upfront."

but in slide 11, why plate removal for ef group?

Great catch. There is no plate removal in the EF group — that is exactly the point.
The EF group had zero plate removals, because external fixators are routinely removed in clinic/outpatient at 5–6 weeks as a planned, standard step of the treatment. It is not counted as a complication — it is just part of the procedure.
Plate removal in the VLP group (5 patients, 7%) happened because of problems such as:
  • Tendon irritation or impingement from the plate
  • Hardware prominence causing discomfort
  • Infection around the plate
  • Patient request due to pain from the implant
These were unplanned extra surgeries under anaesthesia — that is why they are counted as a complication.

So the correct way to say it in your presentation:

"Plate removal was a complication unique to the VLP group — 5 patients (7%) required unplanned surgery to remove their plate due to hardware-related problems. The EF group had no equivalent complication, because fixator removal is a routine planned outpatient step, not an operative complication."

Bottom line

The slide wording "plate removal: 5 (7%) vs 0, p = 0.025" is comparing:
  • VLP: unplanned reoperation to remove a symptomatic plate
  • EF: no such complication exists — the frame was always going to come off

discussion?

Discussion — Slide Content & Presenter's Notes


SLIDE — Discussion

Key Discussion Points:
  • Primary finding in context: VLP superiority at 6 weeks is consistent with prior smaller RCTs (Williksen 2013, Wilcke 2011) — this study is the largest to confirm it with Level I evidence.
  • Why does EF catch up? Once the fixator is removed at 5–6 weeks and physiotherapy begins, EF patients mobilise rapidly. The early disadvantage is largely mechanical — the frame physically immobilises the wrist — not biological.
  • The 1-year equivalence debate: Several previous studies suggested VLP was superior long-term. This larger, well-powered RCT challenges that assumption. The authors argue prior studies were underpowered or had methodological flaws.
  • Wrist extension at 1 year: The persistent 5° advantage in extension for VLP (p = 0.013) is statistically significant but its clinical relevance is debatable. Normal wrist extension is ~70° — both groups achieved >85% of that.
  • Plate removal as a hidden cost: VLP is already a more expensive implant. Adding unplanned plate removal surgery in 7% of patients increases the cost burden further — relevant for health systems and resource-limited settings.
  • EF still relevant: In elderly patients, those on anticoagulation, poor bone stock, or where implant cost is a concern — EF remains a perfectly valid option given equivalent 1-year outcomes.
  • Shift in practice should be evidence-based: The global swing toward VLP happened largely without Level I evidence. This RCT provides that evidence — and it partially justifies VLP for early recovery, but does not support abandoning EF.

Presenter's Notes

"The discussion section is where the authors put their results into the broader context of existing literature.
The key message is that this study confirms and quantifies what surgeons have suspected — VLP gets patients better faster, but EF patients catch up by 1 year. The early advantage of VLP is largely explained by the fact that the external fixator physically immobilises the wrist joint for 5–6 weeks. Once it comes off, EF patients recover quickly.
The authors challenge earlier studies that claimed VLP superiority at 1 year — pointing out that most were underpowered or had shorter follow-up. This is the largest RCT on this specific fracture type, which gives its null finding at 1 year more weight.
The persistent wrist extension advantage for VLP is acknowledged but the authors are cautious — both groups achieved functional extension for daily activities.
The plate removal finding is an important practical point. VLP already costs more as an implant. When you add unplanned surgery in 7% of patients, the cost-benefit balance shifts — especially in settings where resources matter.
The authors conclude that both techniques are acceptable, but VLP should be preferred when early functional recovery is the priority — for example, in working-age patients or those who cannot afford weeks of limited wrist use."

Presenetrs notes for conclusion and limitations - short and sweet

SLIDE 12 — Conclusion

Presenter's Notes

"The bottom line is simple — VLP wins early, but both techniques are equal at 1 year. If your patient needs to get back to function quickly — working age, active lifestyle — VLP is the better choice. If cost, comorbidities, or implant risk are concerns, EF gives the same result at 1 year. The only lasting advantage of VLP was wrist extension, and 7% of VLP patients needed an unplanned second operation to remove their plate. So the choice should be individualised, not dogmatic."

SLIDE 13 — Study Limitations

Presenter's Notes

"A few limitations worth flagging. Surgeons could not be blinded — that is unavoidable in surgical trials, but it is a bias risk. The cohort was 89% female and from a single country, so be cautious about applying these results to younger males or different healthcare settings. The study only covers extra-articular fractures — we cannot extend these conclusions to intra-articular or comminuted types. And follow-up stops at 1 year — we have no data on late complications like tendon rupture or post-traumatic arthritis. These limitations do not invalidate the findings, but they define the boundaries of what we can conclude."

Comparison of 4 Reference Papers vs Ludvigsen 2021


PAPER 1

Xie et al. (2013) — Meta-Analysis Acta Orthopaedica | PMID: 23594247
  • Design: Meta-analysis of 10 RCTs
  • Fracture type: All distal radius fractures (articular + extra-articular)
  • Key result: VLP had better DASH scores at 3 and 6 months, but the difference disappeared at 12 months — consistent with Ludvigsen. VLP also gave better supination at 3 months and better radiographic restoration.
  • Vs Ludvigsen: Agrees — same pattern of early VLP advantage, equivalent at 1 year.

PAPER 2

Williksen et al. (2015) — RCT with 5-year follow-up J Hand Surgery Am | PMID: 25914018
  • Design: RCT, 111 patients, unstable distal radius fractures, 5-year follow-up
  • Key result: No significant difference in QuickDASH at 5 years (VLP 10 vs EF 13). VLP had marginally better supination and radial deviation. Crucially, 21% of VLP plates were removed due to complications.
  • Vs Ludvigsen: Agrees on equivalence at long-term follow-up. However, Williksen found a much higher plate removal rate (21%) compared to Ludvigsen's 7% — suggesting plate removal is an underestimated problem in VLP. Williksen also showed equivalence persists beyond 1 year, out to 5 years.

PAPER 3

Mellstrand Navarro et al. (2016) — RCT J Orthopaedic Trauma | PMID: 26709818
  • Design: RCT, 140 patients, aged 50–74 years, dorsally displaced distal radius fractures
  • Key result: No significant difference in DASH or PRWHE at 3 months or 1 year. EuroQol (quality of life) was lower in EF group in the first 6 weeks — meaning EF patients had worse quality of life early on. Total complication rates were equal between groups.
  • Vs Ludvigsen: Strongly agrees — equivalent outcomes at 1 year and inferior early quality of life with EF. Focused on older patients (50–74 yrs) similar to Ludvigsen's mean age of 56.

PAPER 4

Gou et al. (2021) — Systematic Review & Meta-Analysis BMC Musculoskeletal Disorders | PMID: 33980198
  • Design: Meta-analysis of 12 RCTs, 1,205 patients
  • Key result: VLP had significantly lower DASH scores at 3, 6, and 12 months — suggesting VLP superiority even at 1 year. However, EF had better grip strength at 3 and 6 months. No difference in radiographic outcomes. VLP had a lower overall complication rate.
  • Vs Ludvigsen: Partially disagrees — Gou found VLP had better DASH even at 12 months, while Ludvigsen found no significant difference at 1 year. This discrepancy is likely because Gou pooled all fracture types (including intra-articular), whereas Ludvigsen studied only extra-articular (type A3) fractures. Also noteworthy — Gou found EF had better grip strength early, which Ludvigsen did not highlight.

Summary Table

Mellstrand Navarro 2016RCT14012 monthsYes (QoL)YesYes
Gou 2021Meta-analysis1,20512 monthsYesPartial disagreementPartially — includes intra-articular

Overall message: The weight of evidence — including 3 of these 4 papers — supports Ludvigsen's conclusion that VLP gives faster early recovery but both techniques are equivalent at 1 year for extra-articular distal radial fractures. The main outlier (Gou 2021) likely differs because it pooled mixed fracture types.

from the reference u have given before, kindly compare and let me know the results

Here is a comparison of the 10 references listed in your original slide 14 against Ludvigsen 2021.

Reference 1

Ludvigsen T et al. (2021) — THE INDEX PAPER J Bone Joint Surg Am | PMID: 33369985
  • Design: Multicenter RCT | n = 156 | Extra-articular only (OTA/AO type A3)
  • Result: VLP significantly better PRWHE at 6 weeks (27 vs 44, p<0.001). No difference at 1 year. Wrist extension favoured VLP at 1 year. Plate removal 7% in VLP only.

Reference 2

Margaliot Z et al. (2005) J Hand Surg Am
  • Design: Meta-analysis of RCTs comparing EF vs plate fixation
  • Result: VLP showed better functional outcomes and fewer complications than EF. Early studies suggested VLP superiority — but most included studies were small and underpowered.
  • Vs Ludvigsen: This older meta-analysis leaned toward VLP being superior. Ludvigsen's larger, better-powered RCT later showed equivalence at 1 year — partially contradicts Margaliot's conclusion.

Reference 3

Williksen JH et al. (2013) J Hand Surg Am
  • Design: RCT | n = 111 | Unstable distal radius fractures | 1-year follow-up
  • Result: VLP had significantly better DASH and PRWHE at 3 months. No significant difference at 1 year. VLP had better radiographic outcomes. Complication rates similar.
  • Vs Ludvigsen: Strongly agrees — same pattern. VLP wins early, groups equal at 1 year.

Reference 4

Wei DH et al. (2009) J Bone Joint Surg Am
  • Design: RCT | n = 88 | Three arms — EF, radial column plate, VLP | Unstable distal radius
  • Result: No significant difference in DASH scores between any of the three groups at 12 months. VLP group had better grip strength early. EF had more pin-tract infections.
  • Vs Ludvigsen: Agrees — no functional difference at 1 year. Confirms EF pin-site infection is the main EF-specific complication, just as plate removal is the VLP-specific complication in Ludvigsen.

Reference 5

Orbay JL & Fernandez DL (2004) J Hand Surg Am
  • Design: Case series (not an RCT) | VLP only | Elderly patients with unstable distal radius fractures
  • Result: VLP gave excellent anatomical restoration and early mobilisation. Described the technique and established VLP as a viable approach for unstable fractures.
  • Vs Ludvigsen: This is a foundational technique paper — it helped popularise VLP. Ludvigsen later tested VLP in a rigorous RCT and confirmed early functional gains, validating what Orbay proposed — but showed EF is equally good at 1 year.

Reference 6

Wilcke MK et al. (2011) Acta Orthopaedica
  • Design: RCT | n = 80 | Unstable distal radius fractures | 1-year follow-up
  • Result: VLP group recovered wrist function significantly faster at 3 months. At 1 year, no significant difference in DASH or range of motion between groups.
  • Vs Ludvigsen: Agrees completely — faster recovery with VLP, equivalent outcomes at 1 year. Ludvigsen's larger study replicates and confirms Wilcke's finding.

Reference 7

Cui Z et al. (2011) International Orthopaedics
  • Design: Meta-analysis | Unstable distal radius fractures | VLP vs EF
  • Result: VLP had significantly better DASH scores at 3 and 6 months. At 12 months the advantage persisted but was smaller. VLP had better radiographic restoration of volar tilt. EF had more minor complications (pin-site infections).
  • Vs Ludvigsen: Partially agrees — Cui found a persisting VLP advantage at 12 months, while Ludvigsen found equivalence. Difference likely due to Cui pooling mixed fracture types, while Ludvigsen focused on extra-articular only.

Reference 8

MacDermid JC et al. (1998) J Orthopaedic Trauma
  • Design: Validation study — development of the PRWHE score
  • Result: PRWHE demonstrated excellent reliability, validity, and responsiveness for measuring wrist pain and disability. MCID approximately 14 points.
  • Vs Ludvigsen: This is the methodological backbone of the index paper. Ludvigsen used PRWHE as the primary outcome precisely because MacDermid validated it as the gold standard wrist-specific tool.

Reference 9

Beaton DE et al. (2005) J Bone Joint Surg Am
  • Design: Methodological study — development of QuickDASH from the full 30-item DASH
  • Result: QuickDASH (11 items) showed comparable validity and reliability to the full DASH, with high correlation. Suitable for clinical and research use.
  • Vs Ludvigsen: Another methodological reference. Justifies the use of QuickDASH as a secondary outcome in Ludvigsen's trial.

Reference 10

ClinicalTrials.gov NCT01904084
  • Type: Trial registration record
  • Content: Pre-registered protocol for Ludvigsen's trial — confirms the study design, outcomes, and analysis plan were registered before data collection, reducing risk of outcome-switching bias.
  • Vs Ludvigsen: This is the trial registration of the index paper itself — confirms transparency and methodological integrity.

  • 2 older papers (Margaliot 2005, Cui 2011) lean toward persistent VLP superiority — but both pooled mixed fracture types and included older, weaker studies.
  • 2 papers are validation/tool studies — they justify the outcome measures used.
  • 1 paper is a technique paper — establishes VLP feasibility but makes no comparative claims.
  • The overall consensus in the literature supports Ludvigsen's conclusion.

pivd vs lcs how the differentiate in history

Great clinical question. Here is how to differentiate PIVD (Prolapsed Intervertebral Disc) from LCS (Lumbar Canal Stenosis) on history alone.

Key Differentiating Features on History

FeaturePIVDLCS
AgeYounger (20–45 years)Older (>50 years)
OnsetSudden — after lifting, bending, twistingGradual — insidious over months/years
Pain characterSharp, shooting, electric shock-likeDull, aching, cramping, heaviness
RadiationFollows a specific dermatomal pattern (L4, L5, S1)Bilateral, diffuse, poorly localised — both legs
Back pain vs leg painBack pain + leg pain — leg pain often dominantLeg pain dominant — back pain may be mild or absent
Posture effect on painWorse on sitting, forward bending, ValsalvaWorse on standing and walking
Relief of painLying flat relieves painSitting or bending forward relieves pain
WalkingCan walk but pain radiates down legCannot walk far — stops due to leg pain/heaviness
CyclingPainful — flexion may aggravateComfortable on cycling — forward lean opens canal
Shopping trolley signAbsentPresent — leans forward on trolley for relief
Neurogenic claudicationAbsentPresent — hallmark of LCS
Bladder/bowelOnly in massive central disc prolapseCan occur in severe stenosis
Rest painCommonAbsent at rest

The Single Most Important Distinction

PIVD — Posture dependent pain

Pain is position-specific — worse sitting, better lying flat. One leg affected.

LCS — Activity dependent pain (Neurogenic Claudication)

Pain comes on with walking a fixed distance, relieved by sitting or stooping forward. Both legs affected.

Classic History Scripts

PIVD Patient says:

"I bent down to pick something up and got sudden severe back pain shooting down my left leg to my foot. I can't sit for more than 10 minutes. Lying down is the only relief."

LCS Patient says:

"When I walk about 200 metres my both legs become heavy and numb and I have to stop and sit down. After sitting for a few minutes I can walk again. I am fine at rest and I can ride my bicycle without any problem."

One Quick Memory Trick

"Young person, one leg, sitting hurts = PIVD" "Old person, both legs, can't walk but can cycle = LCS"

how to elaborate the h/o activities of daily living in spine history presentation

Activities of Daily Living (ADL) in Spine History — How to Elaborate

When presenting a spine case, ADL tells the examiner how disabled the patient actually is. Cover these domains systematically.

1. Mobility & Ambulation

  • Walking distance — how far can the patient walk before pain stops them?
    • "He can walk only 100 metres before he has to stop due to leg heaviness"
  • Walking aid — unaided, stick, walker, wheelchair?
  • Does rest relieve it? How long before they can walk again?
  • Climbing stairs — can they manage steps at home?
  • Getting up from a chair — any difficulty rising from sitting?

2. Sitting Tolerance

  • How long can they sit continuously?
    • "He cannot sit for more than 15 minutes due to back and leg pain"
  • Worse on soft sofa or hard chair?
  • Can they sit through a meal / car journey?

3. Standing Tolerance

  • How long can they stand in one place?
    • "He cannot stand at the kitchen counter for more than 5 minutes"
  • Relevant for LCS — standing worsens neurogenic claudication

4. Self-Care

  • Bathing/showering — can they stand in the shower? Get in and out of a bath?
  • Dressing — can they bend to wear trousers, socks, shoes?
    • "He needs help putting on his socks and footwear due to inability to bend forward"
  • Toileting — can they sit and rise from the toilet independently?
  • Grooming — standing at the sink to brush teeth/shave

5. Domestic Activities

  • Cooking — standing at the stove, reaching overhead for items
  • Household chores — sweeping, mopping, making the bed (bending/twisting)
  • Carrying — shopping bags, groceries
  • Gardening — bending, squatting

6. Sleep

  • Sleep position — which position is most comfortable?
    • PIVD patients often sleep on side with knees flexed
  • Night pain — does pain wake them from sleep?
    • Night pain = red flag (tumour, infection)
  • Number of pillows — relevant in cervical spine
  • Getting in and out of bed — any difficulty?

7. Occupational Activity

  • Nature of work — sedentary desk job vs manual labour vs standing job
  • Currently working or on sick leave?
  • Modifications made — standing desk, reduced hours, light duties
    • "He is a construction worker but has been unable to work for 3 months"

8. Recreational & Social Activity

  • Sports, gym, swimming — what has been given up?
  • Social outings — can they attend family events, travel?
  • Driving — can they drive? Sitting tolerance affects this
    • "He has stopped driving due to inability to sit for more than 20 minutes"

9. Bladder & Bowel — Always Ask

  • Urinary — hesitancy, retention, incontinence, frequency
  • Bowel — constipation, incontinence
  • Perianal sensation — numbness or tingling around the saddle area
  • "He denies any difficulty in passing urine or stools and has no perianal numbness"
  • These are red flag symptoms — must always be asked and documented

10. Sexual Function

  • Relevant in cauda equina and severe central canal stenosis
  • Ask sensitively — "Has there been any change in sexual function?"

How to Present It

Structure it as a flowing paragraph, not a checklist:
"With regard to activities of daily living, the patient is significantly limited. He can walk only about 100 metres on flat ground before bilateral leg heaviness forces him to stop and sit. He is unable to stand for more than 5 minutes. Sitting tolerance is about 20 minutes. He requires assistance to wear his socks and footwear. He has been on sick leave from his job as a driver for the past 2 months. He sleeps on his side with knees bent and denies any night pain. There is no difficulty with bladder or bowel function and no perianal numbness."

how many meters do we call it as neurogenic claudication

There is no fixed number of metres that defines neurogenic claudication. It is defined by the pattern, not the distance.

What Actually Defines Neurogenic Claudication

It is diagnosed by this triad:
1. Pain/heaviness/numbness in legs brought on by walking or standing 2. Relieved by sitting or stooping forward 3. Recurs on walking the same distance again

Why There Is No Fixed Distance

  • One patient may stop at 50 metres, another at 500 metres
  • What matters is that it is reproducible and consistent for that patient
  • The distance typically decreases as stenosis worsens over time
  • The same patient may walk further uphill (spine flexes forward, canal opens) than on flat ground

How to Document It Correctly

Do not say "he has neurogenic claudication because he walks less than 200 metres."
Say:
"He develops bilateral leg pain, heaviness and numbness after walking approximately 100 metres on flat ground, which forces him to stop. The symptoms are completely relieved after sitting for about 5 minutes, following which he can walk the same distance again. He is able to cycle without any symptoms."
That description is neurogenic claudication — regardless of the distance.

Severity Grading by Walking Distance (Clinical Guide Only)

SeverityWalking Distance
Mild> 500 metres
Moderate100–500 metres
Severe< 100 metres
This grading is used clinically to gauge severity and progression — not to diagnose.

Key Point for Exams

If an examiner asks "how far does he walk?" — give the patient's specific distance.
If they ask "what is neurogenic claudication?" — define it by pattern and relief posture, not by metres.
The distance is a measure of severity. The pattern is the diagnosis.

instability pain how can I ask in history

Instability Pain in Spine History — How to Ask

Instability pain has a very characteristic pattern. You are looking for movement-triggered, position-dependent pain that is relieved by stillness or support.

The Core Concept

Instability pain = pain that comes on with movement and transition, not sustained posture
The spine hurts when it is moving between positions, not when it is held still.

Questions to Ask — In Plain Language

1. Transition Pain

  • "Does your back hurt when you change position — like when you go from sitting to standing?"
  • "Is it painful to get up from a chair or out of bed?"
  • "Do you have to push yourself up with your hands when rising from sitting?"

2. Start-up Pain

  • "Is the pain worst for the first few steps after you have been sitting or lying, then eases once you get moving?"
  • "Do you feel stiff and painful when you first get out of bed in the morning, which settles after a few minutes of walking?"

3. Catching or Giving Way

  • "Does your back ever suddenly catch or lock when you bend or twist?"
  • "Do you ever feel like your back is going to give way?"
  • "Does it suddenly go into spasm with a simple movement like reaching forward?"

4. Direction-Specific Pain

  • "Is bending forward painful? Does it hurt more coming back up than going down?"
  • "Do you get pain going from lying flat to sitting up?"
  • "Does twisting or rotating cause pain?"

5. Support-Seeking Behaviour

  • "Do you press your hands on your thighs or a table to support yourself when standing up?"
  • "Do you feel better wearing a belt or brace around your waist?"
  • "Do you find yourself holding onto furniture or walls when moving around?"

6. Activity vs Rest Pattern

  • "Is the pain worse with movement and better when you lie completely still?"
  • "Can you find a comfortable position that completely relieves the pain?"
  • "Does staying in one position — sitting or standing — for too long also start to hurt?"
    • (Instability patients are uncomfortable in sustained postures too — they keep shifting)

7. Night Pain Pattern

  • "Do you wake at night when you turn over in bed?"
  • "Is rolling over in bed painful?"
  • This is a classic instability complaint — rotational movement during sleep triggers pain

Classic Instability Pain History — How It Sounds

"The pain is worst when I get up from sitting — the first few steps are terrible. Once I get going it settles a bit. If I sit or stand too long it starts again. Turning over in bed wakes me up. I have to hold the armrest to get out of a chair. I feel much more comfortable when I wear my lumbar belt."

What You Are Clinically Looking For

When the history suggests instability, think of:
  • Spondylolisthesis — especially degenerative (L4/5) or isthmic (L5/S1)
  • Degenerative disc disease with loss of disc height
  • Post-surgical instability — after laminectomy or discectomy
  • Traumatic instability

One Line Summary for Exams

"Instability pain is characterised by start-up pain, transition pain, a catching or giving-way sensation, pain on turning in bed, and significant relief with a lumbar support or brace."
