Etiology

The numerous causes of limb length inequality can generally be divided into two broad categories: congenital and acquired. Congenital limb length inequality is due to limb hypoplasia syndromes, the most common of which is longitudinal deficiency of the fibula; hemihypertrophy syndromes, such as Klippel-Trénaunay-Weber syndrome; or skeletal dysplasias. Acquired causes include anything that injures or slows the growth of the physis, such as a bony bar due to trauma or infection; shortening, such as that from a femoral fracture with comminution or overriding bone fragments; and any systemic condition that results in asymmetric innervation or vascularization.
