Leg length discrepancy (LLD) or anisomelia, is defined as a condition in which the paired lower extremity limbs have a noticeably unequal length. There are two types of LDD; Anatomical which is a structural limb length inequality, the bones of one lower limb are shorter between the hip and ankle. Functional LLD is a non-structural shortening, it is a unilateral asymmetry of the lower extremity without any shortening of the osseous components of the lower limb.
