(3) Attitude Standing / supine

(5) Movement – Gait Ask the patient to walk.

Antalgic gait

= associated with painful leg or foot Short leg gait

= the patient will dip down the short leg on walking or bear weight bearing

Scissor gait

= legs are adducted. Seen in cerebral palsy Waddling gait

= proximal myopathy High stepping gait

= foot drop

Trendelenburg's

= pelvis tilts down to the opposite site instead tilts up. Seen when hip is painful, weak, dislocated or fractured

Stiff leg

= whole leg swung outwards to clear ground to compensate (circumduction). Seen when hip / knee arthrosed or cannot bend.

(6) Symmetry Compare the two hips on standing.

Fig. 10.41 True and apparent lengths of the lower limbs.

Apparent length True length

True shortening Seen in:

Can be due to old fractures of femur or tibia.

Apparent shortening Seen in:

Adduction contracture of the hip which has to be compensated for by tilting of the pelvis.

SPECIAL TEST

(1) Thomas test

The test must be performed with the patient lying face up a hard surface.

Place your left hand palm upwards under the patient's lumbar spine.

Passively flex both the patient's legs (hips and knees) as far as possible.

Keep the non-test hip maximally flexed (you will feel that the lordotic curve of the lumbar spine remains eliminated). Now ask the patient to extend the test hip.

Incomplete extension in this position indicates a fixed flexion deformity at the hip

Picture on right shows Thomas test on left leg.

Thomas's test measures fixed flexion deformity (inco-mplete extension). This deformity may be masked by compensatory movement at the lumbar spine or pelvis and increasing lumbar lordosis.

(2) Trendelenburg's test

Stand in front of the patient and ask the patient to stand on one leg for 30 seconds and to repeat with another leg.

Normally, the iliac crest on the side with foot off the ground should rise.

The test is abnormal if the hemipelvis falls below the horizontal line.

It maybe caused by gluteal weakness or inhibition from hip pain e.g. osteoarthritis or structural abnormality e.g. coxa vara

Trendelenburg's sign. Powerful gluteal muscles maintain the position when standing on the left leg; weakness of the gluteal muscles results in pelvic tilt when standing on the right

(3) Straight leg test

Greater trochanter Site of shortening

The exact site of shortening is important. Firstly it is important to determine if it is above or below the knee. This is best assessed by flexing both knees to 90°, as illustrated.

Normal

Above the knee Below the knee

Shortening above the knee

In assessing shortening above the knee, it is important to decide whether it occurs above the greater trochanter, or below the trochanter in the femoral shaft itself

Shortening above the greater trochanter can be determined by:

1. Placing one's thumbs on the AS IS with the middle fingers on the tip of the greater trochanters (both side) and compare, using the sense of proprioception (muscle sense).

2. Bryant's Triangle is drawn as follows. The patient lays supine and a line drawn from the ASIS down towards the bed. A second line is then drawn from the ASIS to the tip of the greater trochanter. The third side of the triangle is a horizontal line, drawn proximally from the greater trochanter in the line of the femur to meet the first line drawn. This third line shows the amount of upward or downward displacement of the hip compared to the normal side.

Normal Superior displacement Inferior displacement

1. Hair tuft. discoloration or dimpling at the base of the spine indicates spina bifida

2. Soft tissue swelling may be due to:

-infection -trauma -tumors
