Unequal leg length

Overview
Unequal leg length or leg length inequality (LLI) refers to a medical condition where the legs are of different sizes.

One form is "leg length alignment asymmetry" (LLAA ) is a condition in physiology where one leg (the 'short leg', or unloaded leg) is unequal in length while in a supine or prone position (i.e., laying down).

LLAA can be either anatomical in nature (short bones due to growth or an accident) or neuromuscular (hypertonicity in the musculature of the pelvis or leg).
