What does a positive Derbolowsky Test mean?

The differential diagnosis should consider whether something other than a motion restriction in the sacroiliac joint may be causing the variable leg length difference.


Leg Length Discrepancy

When examining leg length, one must consider the possibility of apparent lengthening or shortening due to an abduction or adduction contracture.

Assessing Leg length Difference LLD

1. Tape measure:

It measures the length of the lower extremity by measuring the distance between the anterior superior iliac spine (ASIS) and the medial malleolus, it’s also called “direct method” for measuring LLD (True Leg Length).

An apparent leg length can be measured from the umbilicus to the medial malleoli of the ankle.

In some cases, lengths of the appendicular skeleton may be equal, but apparent shortening may result from pelvic obliquity or contractures around the hip and knee joints.

2. Standing on Blocks:

This method levels the pelvis of the standing patient by placing blocks of known height under the short limb. It’s also called the “indirect method” for measuring LLD.

3. Imaging Methods:
