1) Plantar Fasciopathy (Plantar fasciitis)

Pathophysiology

• Degenerative-overload condition at proximal plantar fascia origin (medial calcaneal tubercle), often with microtearing and failed healing response.
• Not purely inflammatory in chronic cases.
• Often associated with gastrocnemius-soleus tightness, increasing tensile load on plantar fascia.

Risk factors

Non-modifiable

• Increasing age
• Foot structure (certain arch profiles)
• Occupation with prolonged standing history

Modifiable

• BMI >30 (major risk factor)
• Sudden load increase (running volume/intensity)
• Poor footwear (minimal cushioning/support for task)
• Calf tightness
• Reduced ankle dorsiflexion
• Training errors/recovery deficits

Differential diagnoses (and why not)

• Baxter’s nerve entrapment: neuropathic/burning quality, may be more persistent and less “first-step” classic.
• Calcaneal stress fracture: pain with squeeze/compression, load progression history, often worsening constant pain.
• Fat pad atrophy syndrome: central heel pain, worse on hard surfaces, not classic medial calcaneal tubercle tenderness.
• Spondyloarthropathy enthesitis: bilateral/systemic signs, morning stiffness with other joints.
• Tarsal tunnel syndrome: neural symptoms, Tinel pattern, broader plantar symptoms.

Clinical tests

• Point tenderness at medial calcaneal tubercle: key local sign.
• Windlass test (Jack’s test): passive hallux dorsiflexion increases plantar fascia tension and reproduces symptoms.
• Silfverskiöld test: differentiates gastrocnemius vs soleus tightness by ankle dorsiflexion with knee extended/flexed.
• Functional loading tests: first-step pain after rest, pain after prolonged standing/walking.
• Imaging if atypical/refractory:
  • Weight-bearing foot X-ray first to exclude bony pathology.
  • Ultrasound or MRI for fascia thickening/other causes.

Gait deviations

• Antalgic initial contact, reduced heel loading
• Shortened step length
• Early heel-off or altered rollover
• Possible lateral column loading compensation
• Reduced propulsive efficiency due to pain avoidance

Assessment plan

• Subjective: symptom chronology, first-step pattern, load history, footwear profile
• Objective:
  • Palpation mapping
  • ROM (ankle dorsiflexion)
  • Calf length assessment
  • Foot posture and dynamic pronation/supination pattern
  • Single-leg stance/heel raise capacity
• Outcome measures:
  • VAS/NRS pain
  • Foot Function Index (if used in clinic)

Management

Conservative first-line

• Plantar fascia-specific stretch + calf stretch
• Load modification (relative rest, graded reload)
• Footwear upgrade (cushion + stable rearfoot)
• Temporary taping
• Heel cushioning/orthoses
• Strength work (intrinsics/calf complex as tolerated)

Second-line

• Supervised physiotherapy program
• Night splints in persistent morning pain
• ESWT in recalcitrant cases
• Consider short-term immobilization if severe flare

Last resort

• Surgery for refractory cases after prolonged failed conservative care
• Avoid over-release risk (lateral column overload risk if excessive release)

Footwear advice

• Cushioned heel, stable midsole, adequate torsional stiffness
• Avoid worn-out shoes, very flat unsupportive shoes during flare
• Match shoe to activity; rotate shoes; avoid barefoot hard-floor walking early phase

Orthosis prescription (example, bilateral unless unilateral symptoms)

• Base: EVA 2 mm
• Components:
  • Heel raise 4 mm (if Achilles-gastrocnemius tightness present)
  • PMP (plantar medial posting) 3 mm to support medial arch and reduce fascia strain
  • Optional U/PPT heel cushioning if high heel impact pain
• Wedges:
  • Consider mild RF varus 3° if excessive rearfoot eversion pattern and tolerated
• Top cover:
  • Poron 3 mm (shock attenuation)
• Why:
  • Reduces tensile stress on plantar fascia
  • Improves load distribution and comfort
  • Reduces painful heel impact and excessive pronation moments where present

2) Hallux Limitus / Hallux Rigidus

Pathophysiology

• Progressive 1st MTPJ osteoarthritis: cartilage degeneration, dorsal osteophytes, painful dorsiflexion limitation.
• Functional hallux limitus can begin as dynamic jamming and become structural.

Risk factors

Non-modifiable

• Age
• Prior joint trauma history
• Morphology/genetic predisposition

Modifiable

• Repetitive forefoot overload
• Inappropriate footwear (high heel, narrow toe box, flexible forefoot shoes in painful stages)
• Occupation/sport with repeated toe dorsiflexion stress

Differential diagnoses

• Gout (1st MTPJ): acute inflammatory attacks, swelling/redness, biochemical/systemic context.
• Sesamoiditis/1st ray overload: plantar pain under 1st met head rather than dorsal 1st MTPJ OA pattern.
• Hallux valgus pain: deformity pattern differs; pain focus often medial eminence.
• Inflammatory arthritis: multi-joint/systemic clues.

Clinical tests

• 1st MTPJ ROM goniometry (non-weight-bearing and functional weight-bearing)
• End-range dorsiflexion pain and crepitus
• Dorsal osteophyte palpation tenderness
• Functional toe-off observation (painful/avoidant)
• Weight-bearing foot X-ray:
  • joint space narrowing
  • subchondral sclerosis/cysts
  • dorsal osteophytes

Gait deviations

• Reduced hallux dorsiflexion at terminal stance
• Early heel rise, shortened stride
• Lateral forefoot rollover/compensation
• Possible external foot progression angle to avoid 1st MTPJ dorsiflexion demand

Assessment

• Stage severity (functional vs structural)
• Local deformity/pain provocation
• 1st ray mobility and plantarflexion capacity
• Footwear wear pattern and toe box depth

Management

Conservative first-line

• Footwear stiffening strategy (rocker sole, stiff forefoot)
• Activity modification
• Analgesia as appropriate
• Orthoses to reduce 1st MTPJ dorsiflexion demand

Second-line

• Image-guided injections in selected patients (temporary symptom modulation)
• Custom orthoses optimization

Last resort

• Surgery by stage:
  • cheilectomy in selected earlier structural disease
  • arthrodesis in advanced painful OA (common definitive option)

Footwear advice

• Rocker sole shoes
• Stiff sole to reduce 1st MTPJ bending moment
• Adequate toe box depth/width
• Avoid flexible forefoot and high heels

Orthosis prescription (example)

• Base: Slimflex (or equivalent) for stiffness profile
• Components:
  • Morton’s extension (to hallux) 3 mm firm extension to limit painful 1st MTPJ dorsiflexion
  • Optional met bar/proximal offload if transfer load appears
• Wedges:
  • Case dependent; avoid overposting that worsens jamming
• Top cover:
  • EVA or Poron depending on pain sensitivity
• Why:
  • Splints/limits painful hallux dorsiflexion
  • Shifts rollover mechanics proximally with rocker footwear
  • Reduces dorsal joint compression pain during toe-off

3) Morton’s Neuroma (Interdigital neuritis)

Pathophysiology

• Compressive neuropathic process of interdigital nerve, most often 3rd interspace.
• Chronic compression/shear -> perineural fibrosis and pain.
• Often linked to forefoot squeeze mechanics and footwear compression.

Risk factors

Non-modifiable

• Female sex prevalence reported
• Forefoot anatomical predisposition

Modifiable

• Narrow toe-box shoes
• High heels (forefoot loading + toe crowding)
• Repetitive forefoot loading

Differential diagnoses

• MTP synovitis/capsulitis
• Metatarsalgia
• Stress fracture metatarsal
• Intermetatarsal bursitis
• Lumbar radiculopathy/peripheral neuropathy Why less likely: symptom location, provocation pattern, Mulder findings, imaging/exam distribution.

Clinical tests

• Mulder’s test/sign: mediolateral forefoot squeeze + webspace palpation reproduces pain/click.
• Webspace palpation tenderness (plantar distal intermetatarsal region)
• Forefoot compression test
• Digital nerve symptom provocation (burning/radiation)
• Imaging (if diagnostic uncertainty):
  • ultrasound/MRI supportive, not always required

Gait deviations

• Forefoot offloading
• Reduced terminal stance push-off on involved side
• Lateral border compensation or antalgic pattern
• Shortened stance time

Management

Conservative first-line

• Footwear change is key (wide toe box, lower heel)
• Metatarsal pad proximal to painful area
• Load/activity modification
• Education on aggravating footwear

Second-line

• Corticosteroid injection (short-term/moderate response in selected patients)
• Repeat injection caution due to tissue effects and diminishing returns

Last resort

• Surgical neurectomy for persistent disabling symptoms after adequate conservative care

Footwear advice

• Wide/deep toe box
• Avoid high heels and tight forefoot volume
• Use forefoot cushioning and pressure-spreading insole
• Lace pattern adjustments for forefoot expansion

Orthosis prescription (example)

• Base: EVA 2 mm or Poron 3 mm (if high shock sensitivity)
• Components:
  • Met dome (3 mm standard) placed proximal to met heads
  • Optional met bar for broader offload
  • No direct pressure under neuroma point
• Wedges:
  • Usually minimal unless clear rearfoot driver
• Top cover:
  • Poron 3 mm
• Why:
  • Opens intermetatarsal space functionally
  • Reduces focal neural compression
  • Lowers plantar forefoot peak pressure

4) Achilles Tendinopathy (insertional and non-insertional)

Pathophysiology

• Tendinopathy = collagen disorganization and failed tendon remodeling, minimal classic inflammation.
• Non-insertional commonly 2-6 cm proximal to insertion.
• Insertional involves tendon-bone enthesis, often with calcific/enthesophyte change.
• Load-capacity mismatch central to mechanism.

Risk factors

Non-modifiable

• Age-related tendon changes
• Tendon vascularity factors
• Genetic predisposition

Modifiable

• Royal London Hospital test (tenderness changes with dorsiflexion)
• Arc sign (thickening moves with ankle motion if intratendinous)
• Single-leg heel raise endurance/pain
• VISA-A questionnaire (if used)
• Imaging:
  • Ultrasound/MRI for uncertain diagnosis or recalcitrant cases
  • X-ray for insertional calcification/Haglund profile

Gait deviations

• Reduced ankle dorsiflexion in stance

• Footwear adaptation (rearfoot comfort; reduced insertion compression if insertional)
• Address calf flexibility and strength deficits

Second-line

• ESWT in persistent cases
• Advanced rehab progression with monitored load metrics
• Consider adjuncts case-by-case

Last resort

• Surgical debridement/reconstruction pathways for chronic refractory disease
• In major tendon degeneration, tendon augmentation/transfer strategies may be used

Footwear advice

• Slight heel differential often helpful initially
• Avoid rigid heel counters that irritate insertional area
• Gradual return to plyometric/impact demands
• Track flare response over 24-hour rule

Orthosis prescription (example)

• Base: EVA 2 mm
• Components:
  • Heel raise 4 mm (can increase if clinically indicated)
  • PMP or arch support if excessive pronatory moments increase tendon load
  • Soft heel interface (Poron top cover)
• Wedges:
  • Small RF posting only if clearly indicated biomechanically
• Top cover:
  • Poron 3 mm
• Why:
  • Reduces Achilles tensile/compressive demand early
  • Improves tolerance to walking and rehab loading
  • Controls contributory rearfoot mechanics if present

5) Posterior Tibial Tendon Dysfunction (PTTD) / Adult Acquired Flatfoot Deformity (AAFD)

Pathophysiology

• Progressive failure of posterior tibial tendon and medial arch support complex.
• Leads to hindfoot valgus, forefoot abduction, arch collapse.

Risk factors

Non-modifiable

• Age
• Structural predisposition
• Degenerative tendon biology

Modifiable

• Deltoid/spring ligament injury without PTT primary failure
• Charcot/neuroarthropathy in appropriate risk group
• Inflammatory arthropathy
• Isolated subtalar arthritis Reasoning uses flexibility, single heel raise performance, onset/progression, imaging patterns.

Clinical tests

• Single-limb heel raise test: pain/inability strongly supports PTT insufficiency.
• Too-many-toes sign: forefoot abduction visible posteriorly.
• Hindfoot valgus observation
• Jack test / arch reconstitution tests (flexible vs rigid)
• Silfverskiöld test for equinus contribution
• Imaging:
  • Weight-bearing AP/lateral/oblique foot and ankle radiographs
  • Ultrasound/MRI for tendon integrity in selected cases

Gait deviations

• Prolonged pronation in stance

• Adequate depth for orthosis
• Avoid unsupportive slip-ons/minimalist shoes in symptomatic phase

Orthosis prescription (example)

• Base: Slimflex or firm EVA stack depending on required control
• Components:
  • PMP with wing (3 mm) to improve medial longitudinal arch support and calcaneal control
  • D-filler 6 mm for enhanced medial arch contour if needed
  • Heel raise 4 mm if equinus/Achilles contribution
• Wedges:
  • RF varus 4°-5° (case dependent) to reduce hindfoot valgus moment
  • FF posting based on compensated forefoot position (often FF varus accommodation/correction strategy as indicated)
• Top cover:
  • EVA or Poron depending pressure tolerance
• Why:
  • Increases supination moment support
  • Reduces strain on dysfunctional PTT
  • Improves alignment and gait efficiency in flexible stages
