ABSTRACT
Leg-length discrepancy (LLD) is common; 23% of the general population has a LLD of 1 cm or more (1). The prevalence of LLD requiring a corrective device, such as a lift, is approximately 1 in 1000 (2). This chapter outlines the etiology, functional effects, assessment, and treatment of LLD by epiphysiodesis and other treatment options.
