ü ludloff’s sign( tenderness over AM aspect of thigh at base of scarpa’s triangle – LT affection
SUPINE
CONFIRM above findings
Percussion
Firm pecussion at heel elicits pain at hip in inflammatory condition (Anvil’s test)
DEFORMITIES
Fixed flexion deformity: Thomas test
Prerequisites
1.U/L Deformity
2.No bony ankylosis in other hip & knee
3.Other hip should be painless
4.Ipsilateral hip should not be very painful
5.No fixed pelvic/ spinal deformity
THOMAS TEST
ØStand on right side of couch
ØPass hand behind volar side up
ØAsymptomatic limb to flex hip & knee to fullest obliterating lumbar lordosis
ØAsk pt to hold limb in same position
ØPassively gently extend  affected limb at thigh to correct overcorrection.
ØMeasure angle after reconfirming obliteration of lordosis.
THOMAS TEST
BILATERAL DEFORMITY
Do the test in prone position
Both lower limbs hanging off the couch
Support both thighs
Obliterate lumbar lordosis in direct vision
Mesure flexion deformity from imaginary horizontal parallel to floor
THOMAS TEST
Drawbacks
Coexisting abduction/adduction deformity
Painful hip
Obese & uncooperative pts
Difficult to do prone test
Principle
Fixed sagittal plane deformity is compensated by pelvic extension & vice versa
DEFORMITIES
Fixed adduction & abduction deformity: by squaring pelvis
Squaring is done to remove effect of compensation by body  by reversing deformity prooduced d/t compensation.
Abducting the limb in fixed abduction deformity &  vice versa
DEFORMITIES
Fallacies of squaring pelvis
*Absent ASIS d/t previous surgery
*Fixed pelvic obliquity/ scoliosis
*Malformed pelvis
*Deformed pelvis eg. Following trauma
*AS with fixed spine & ankle deformities
Fixed rotational deformities : has to be measured  by using goniometer
Center of heel to 2nd toe as reference
MOVEMENTS
Hold the pelvis firmly with left hand with thumb at the ASIS & fingers embracing trochanter
FLEXION
1st reveal deformity by THOMAS test & then passively move limb further & measure range taking couch as reference
ADDUCTION /ABDUCTION
First square the pelvis
Measure range of respective movement taking body midline as reference
20° abduction means 20° abduction beyond deformity
Rotational movements
Measure both in extension & flexion at hip
Extension : measure from zero position (patella horizontal to ceiling)
In flexion: hip flexed at 90° & leg parallel to midline
EXTENSION
In prone position
MEASUREMENTS
APPARENT LENGTH
in unsquared pelvis
Limbs lying parllel
Xiphisternum to medial malleolus
TRUE LENGTH
square pelvis
Limbs in mirror image (flexion  at hip)
Measure from ASIS to MM
WASTING
Thigh circumference 15 cm from medial knee joint line
Femoral & tibial length
Galleazi sign & Allis test
BRYANT TRIANGLE
Square pelvis
Draw a line from ASIS Laterally horizontal (Perpendicular to midline)
Line joining tip of trochanter to ASIS
Tip of trochanter to intersect  joint 1st line(base)
Femoral anteversion:
Craig’s test, Ryder method
Special tests
Qualitative assesment of supratrochanteric shortening
o Nelaton’s line: lateral position
Affected side up
Flex hip to 90°
Join ischial tuberosity to ASIS
Supratrochanteric shortening: if tip of GT crosses this line
oShoemaker’s line
Supine
Join tip of trochanter to ASIS & extend it to abdomen crossing umblicus
Similar line to opposite side
Normally crosses at or above umblicus in midline
In suprotrochanteric shortening, line misses umblicus & lies below on opposite side.
oChiene’s line
Lines joining both ASIS & Both trochanter – parallel
Converge on side of upriding
TESTS FOR STABILITY
Active SLRT (Stinchfield’s test): indicates dislocation/ fracture of neck or hip joint instability
Trendlenberg test

Abductor as power
Prerequisites

TRENDLENBERG TEST
Stand behind pt
Observe angle b/w pelvis (line joining iliac crest) & ground
Stand on unaffected side 1st
Lifting affected side foot & flexing hip b/w neutral & 30° &  knee to clear .
Raise affected side as high as possible
Repeat on affected side
Normally (negative test): able to lift other side without losing balance for at least 30 sec & lift is equal to abduction possible at that hip.

Ludloff’s test
Inability to raise thigh in sitting postion specially against resistance
Lesser trochanter avulsion fracture
Gear stick sign
Limitation of abduction in extension
improves with flexion of hip
Sectoral sign
Osteonecrosis
Reduced internal rotation in extension
Improves when check in flexion

Schober test
Mark 2 pts
