Lower limb examination
An introductory lecture
STANDARD APPROACH
LOOK
FEEL
MOVE
SPECIAL TESTS
Regional approach
• Hip
• Knee
• Foot (diabetic)
HIP
LOOK
• Gait…
In hip: short limb gait
trendelenburg gait
antalgic gait
• Scars, sinuses, skin changes, deformities
• Trendelenburg test
Standing on affected leg: pelvis falls to unaffected
side, body swerves to affected side to compensate
FEEL
• Temperature
• Joint palpation (tenderness)
– GT
– ASIS
– Joint line
– Pubic symphisis
MOVE
• Flexion: 0 – 140
– Thomas test
Right Thomas test positive
100
• Abduction: 0 – 45
• Adduction: 0 – 30
• Internal rotate: 0 – 40
• External rotate: 0 – 50
SPECIAL TESTS
Limb length measurement
• To determine site of shortening
• Start with galeazzi test
• Then proceed with Bryant’ triangle
• Measure apparent length:
– Umbilicus to medial malleolus
• Measure true length:
– ASIS to medial malleolus
Summary hip
• Look
• Feel
• Move
• Special test
+ Trendelenburg test
+ Thomas test
+ LLD measurement
KNEE
LOOK
• Gait patterns: antalgic, lateral thrust
• Front, side, back:
– Deformities, swellings, wasting, sinus,
scars, skin changes
• Sit at side of table:
– Assess patella tracking (inverted J)
– Measure Q – angle • ♂ - 14 ♀ - 17
FEEL
• Temperature
• Effusion assessment
– Cross fluctuation – large
– Patella tap – medium
– Bulge test – little
– Hollow test – minimal
• Joint line tenderness
– may suggest meniscus involvement
MOVE
• Flexion: active, passive
• Extension: active, passive
SPECIAL TESTS
Aims
• To determine internal knee
structures integrity
• To assess patellofemoral joint
stability
Knee integrity
• Posterior sagging sign – PCL
• Drawer’s test – anterior and posterior
• Lachman’s test – ACL
• Varus and valgus test – MCL, LCL
• McMurray test – ?
Done in 0 and
30 degrees
PFJ assessment
• Palpate the patella and its
undersurface – tenderness
• Patella apprehension test
Summary knee
• Look
• Feel
• Move
• Special test
+ patella tracking, Q angle
+ effusion assessment
+ internal knee integrity
+ PFJ assessment
FOOT (DIABETIC)
• Vasculopathy
• Immunopathy
• Neuropathy
– Motor
– Sensory
– Autonomic
LOOK
• Wounds, ulcer, gangrene
• Deformities
• Immunopathy – cellulitis features
• Vasculopathy – loss of hair
• Neuropathy
– Motor – claw toes,
callosities
– Autonomic – dry skin
FEEL
• Immunopathy – warmth, tender
• Vasculopathy – pulses, cold
peripheries, CRT
MOVE
• Ankle – active and passive
• Tightness of tendon Achilles
– Due to glycolisation products
deposition
SPECIAL TESTS
• Neuropathy
– Sensory – glove and stocking
– Monofilament – assess protective
sensation
• Ankle-brachio systolic index (ABSI) –
0.8 – 1.0 ratio
King’s classification
• Stage 1 – normal foot
• Stage 2 – foot at risk
• Stage 3 – ulcerated foot
• Stage 4 – infected foot
• Stage 5 – necrotic foot
• Stage 6 – major amputation
Summary foot (diabetic)
• Aim to detect features of:
– Vasculopathy
– Immunopathy
– Neuropathy
• Classify the foot (King’s)
