"McKenzie Method" AND low back pain

McKenzie Method mechanical diagnosis therapy patient information low back pain guideline

The McKenzie approach, formally called Mechanical Diagnosis and Therapy (MDT), is a physiotherapy assessment and treatment system most often used for low back and neck pain.

Core idea

Rather than giving everyone the same exercise, the clinician tests how symptoms respond to repeated movements and sustained postures, then selects exercises that reduce or “centralize” pain.
Centralization means pain that is felt in the buttock, thigh, or leg moves back toward the low back. This is usually a favorable response. Pain spreading farther down the limb is generally an unfavorable response.

Assessment and classification

An MDT-trained clinician takes a detailed history and repeatedly tests movements, commonly:
  • Bending forward (flexion)
  • Bending backward (extension)
  • Side-gliding or side-bending
  • Sustained sitting or standing postures
They then classify the problem broadly as:
  1. Derangement syndrome: symptoms change rapidly with particular movements or positions. This is often the group with a directional preference.
  2. Dysfunction syndrome: pain occurs reproducibly when shortened or stiff tissues are stretched at end range.
  3. Postural syndrome: pain develops with sustained loading, often with otherwise normal movement.

Directional preference

A key concept is finding the movement direction that improves symptoms. For example:
  • Some people improve with repeated extension movements, such as prone lying or press-ups.
  • Others improve with flexion movements, such as knees-to-chest.
  • Others need lateral movements first.
So McKenzie is not simply “back extension exercises.” Extension is common in practice, but the appropriate direction should be based on the individual response.

Typical treatment components

  • Repeated, symptom-guided movements
  • Posture and ergonomic advice
  • Frequent self-treatment during the day
  • Progression from pain reduction to restoring movement, then strength and function
  • Education to help the person manage future flare-ups
The approach emphasizes self-management rather than relying only on passive treatments. The StatPearls overview describes MDT as a classification-based approach that uses repeated end-range movements and postural correction.

Evidence

A 2025 systematic review and meta-analysis found that McKenzie Method treatment delivered by credentialed therapists may improve outcomes in people with chronic low back pain who have a directional preference, but it should be selected for the patient rather than used as a universal protocol (Hennemann et al., 2025, PMID 39383118). It is best viewed as one active, exercise-based option within a broader rehabilitation plan.

Important safety point

Do not keep doing a movement if it:
  • Makes pain travel farther down the arm or leg
  • Causes new or worsening weakness, numbness, or loss of coordination
  • Produces bowel/bladder changes or saddle-area numbness
  • Is associated with fever, unexplained weight loss, major trauma, or cancer history
Those features need prompt clinical assessment. A physiotherapist trained in MDT can identify your directional preference and prescribe the appropriate version safely.

Which condition or operation do you mean by the surgical approach?
For example: lumbar disc prolapse, hip fracture, scoliosis, cervical spine, or another condition.

im preparing for ms ortho knruhs practical examinations give me a quick 10 point short note to revice reproduce in my viva about surgical approaches given by me 1. mckenzie 2.kaplan 3.smith peterson 3.southern

1. McKenzie approach to hip - lateral approach

  1. Type: Direct lateral approach to the hip.
  2. Position: Lateral decubitus, affected limb uppermost.
  3. Landmark: Greater trochanter.
  4. Skin incision: Longitudinal incision centered over the greater trochanter.
  5. Superficial dissection: Incise fascia lata in line with the skin incision.
  6. Muscle handling: Split gluteus medius in line with its fibres or detach its anterior portion with vastus lateralis.
  7. Deep exposure: Expose the anterior capsule of hip.
  8. Capsulotomy: T-shaped or longitudinal capsulotomy.
  9. Uses: Hip hemiarthroplasty, total hip replacement, fracture neck of femur.
  10. Complication: Superior gluteal nerve injury causing abductor weakness and Trendelenburg gait.

2. Kaplan approach to elbow - lateral approach

  1. Type: Lateral approach to elbow, especially radial head and capitellum.
  2. Position: Supine or lateral position, elbow flexed and forearm pronated.
  3. Landmarks: Lateral epicondyle, radial head and posterior border of ulna.
  4. Skin incision: Curved or longitudinal incision over lateral epicondyle, extending distally toward radial head.

  6. Deep dissection: Split capsule and annular ligament anterior to the lateral collateral ligament complex.
  7. Exposure: Radial head, neck, capitellum and anterior elbow joint.
  8. Forearm position: Keep forearm pronated to move posterior interosseous nerve away from operative field.
  9. Uses: Radial head fracture fixation/replacement, capitellar fractures, lateral elbow arthrotomy.
  10. Danger: Posterior interosseous nerve injury and damage to lateral collateral ligament leading to posterolateral rotatory instability.

3. Smith-Petersen approach to hip - anterior approach

  1. Type: Classical anterior approach to hip.
  2. Position: Supine, with a sandbag under ipsilateral buttock if required.
  3. Landmarks: ASIS and greater trochanter.
  4. Skin incision: Starts just lateral and distal to ASIS, directed distally toward the lateral aspect of patella.
  5. Superficial interval: Between tensor fascia lata (TFL) laterally and sartorius medially.
  6. Nerve at risk: Lateral femoral cutaneous nerve, which lies near the medial side of the interval.
  7. Deep interval: Retract rectus femoris medially and TFL/gluteus medius laterally.
  8. Exposure: Anterior capsule of hip, femoral neck and anterior acetabulum.
  9. Uses: Open reduction of developmental dysplasia of hip, anterior hip arthroplasty, drainage of hip joint.
  10. Complications: Lateral femoral cutaneous nerve neuropraxia, injury to ascending branch of lateral circumflex femoral artery, postoperative heterotopic ossification.

4. Southern approach to hip - posterior approach

  1. Type: Posterior or posterolateral approach to hip, also called Southern-Moore approach.
  2. Position: Lateral decubitus, affected hip uppermost.
  3. Landmarks: Posterior superior iliac spine and greater trochanter.
  4. Skin incision: Curved incision centered over posterior aspect of greater trochanter.
  5. Superficial dissection: Split gluteus maximus in line with its fibres.
  6. Important structure: Sciatic nerve lies posteriorly and must be identified/protected.
  7. Muscles detached: Piriformis, obturator internus with gemelli, and sometimes quadratus femoris are divided close to trochanter.
  8. Capsulotomy: Posterior capsulotomy, usually T-shaped.
  9. Uses: Posterior hip dislocation, hemiarthroplasty, total hip replacement, posterior acetabular procedures.
  10. Main complication: Posterior dislocation after THA; also sciatic nerve injury and abductor-sparing but higher instability risk.

McKenzie shoulder surgical approach

You are right. I was wrong in my earlier answer.
McKenzie (Mackenzie) approach is an anterolateral deltoid-splitting approach to the shoulder/proximal humerus, not a standard hip approach.

Correct association for viva

  • McKenzie approach: shoulder, anterolateral deltoid split
  • Kaplan approach: lateral elbow, radial head/capitellum
  • Smith-Petersen approach: anterior hip
  • Southern-Moore approach: posterior hip

McKenzie approach: one-line viva answer

“McKenzie approach is an anterolateral approach to the proximal humerus, using a split in the deltoid, mainly for proximal humeral fracture fixation and shoulder arthroplasty; the axillary nerve is the key structure at risk.”

Key correction to your short note

  • Patient: beach-chair or supine position
  • Incision: from anterolateral acromion distally over deltoid
  • Deltoid is split in line with its fibres
  • Do not extend the split more than about 5 cm distal to the acromion without identifying/protecting the axillary nerve
  • Uses: proximal humerus ORIF, intramedullary nailing, selected shoulder arthroplasty
  • Risks: axillary nerve injury, deltoid dysfunction, injury to posterior circumflex humeral vessels
The literature also calls it the anterolateral, anterior deltoid-split, or Mackenzie approach (review of anterolateral proximal-humerus approaches).

For your viva list, the correct associations are:
EponymRegionApproach
HotchkissElbowMedial “over-the-top” approach to coronoid/anterior-medial elbow
InsallKneeAnterior midline incision with medial parapatellar arthrotomy
Kocher-LangenbeckHip/acetabulumPosterior approach to acetabulum and hip
KaplanElbowLateral approach to radial head and capitellum

Important correction

It is Kocher-Langenbeck, not usually “von Langenbeck” alone, in modern orthopaedic viva terminology. It is the posterior approach for posterior wall/posterior column acetabular fractures.

Rapid viva recall

1. Hotchkiss approach

  • Medial elbow, also called the over-the-top approach.
  • Exposure: anterior capsule and tip of coronoid.
  • Elevate flexor-pronator mass anteriorly from the medial side.
  • Identify and protect ulnar nerve.
  • Uses: coronoid fracture fixation, medial collateral ligament work, terrible-triad injuries.
  • Limitation: relatively poor access to coronoid base/medial facet compared with FCU-splitting approaches.

2. Insall approach

  • Standard anterior approach for the knee and total knee arthroplasty.
  • Midline skin incision.
  • Medial parapatellar arthrotomy.
  • Incision runs medial to patella and quadriceps tendon, extending into medial retinaculum.
  • Patella is everted or subluxed laterally.
  • Uses: TKA, knee arthrotomy, patellar procedures.
  • Risk: infrapatellar branch of saphenous nerve, patellar blood supply if extensive lateral release.

3. Kocher-Langenbeck approach

  • Posterior approach to acetabulum/hip.
  • Position: prone or lateral decubitus.
  • Incision: from near PSIS, across greater trochanter, then down lateral femur.
  • Split gluteus maximus.
  • Identify and protect sciatic nerve.
  • Detach/tag short external rotators, preserving repair for closure.
  • Exposure: posterior wall, posterior column, retroacetabular surface.
  • Uses: posterior wall/column acetabular fractures and selected revision hip procedures.
  • Major risks: sciatic nerve injury, damage to medial femoral circumflex vessels, heterotopic ossification.

4. Kaplan approach

  • Lateral approach to elbow for radial head/capitellum.
  • Interval: ECRB and EDC.
  • Not ECRL and EDC: that was an error in my earlier reply.
  • Forearm is pronated to move the posterior interosseous nerve away.
  • Open capsule and annular ligament anterior to the LUCL.
  • Exposure: radial head, radial neck, capitellum, anterior radiocapitellar joint.
  • Uses: radial-head ORIF/replacement and capitellar fracture fixation.
  • Risks: PIN injury and lateral collateral ligament injury causing posterolateral rotatory instability.
The surgical-approach summary in Campbell’s Operative Orthopaedics lists Kaplan as the lateral elbow interval between ECRB and EDC, and Hotchkiss among medial elbow approaches - Campbell’s Operative Orthopaedics, 15th ed., p. 131. The AO description of Hotchkiss exposure confirms its coronoid-tip/anterior elbow exposure.
