Abstract
Limb length discrepancy, or anisomelia, is defined as a condition in which paired limbs are noticeably unequal. When the discrepancy is in the lower extremities, it is known as leg length discrepancy (LLD). LLD is a relatively common problem found in as many as 40 to 70% of the population.LLD of greater than 20 mm affects at least one in every 1000 people. The effects of LLD on function and the magnitude of LLD warranting treatment have became subjects of controversy for some time.LLD can be subdivided into two etiological groups: a structural LLD (SLLD) defined as those associated with shortening of bony structures, and a functional LLD (FLLD) defined as those resulting from altered mechanics of the lower extremities. In addition, persons with LLD can be classified into two categories, those who have had LLD since childhood, and those who developed LLD later in life. In terms of functional outcomes such as gait, persons who have developed a LLD later in life are more debilitated by LLD of the same magnitude when compared to persons who have had LLD since childhood.There is disagreement regarding the role LLD plays in musculoskeletal disorders and the acceptable amount of LLD necessary to warrant treatment. Perhaps the most controversial musculoskeletal disorder associated with LLD is LBP.
