Abstract: Leg-length discrepancy is a condition associated with several factors that can affect growth rate, length itself, or both. Treatment decisions depend on an accurate prediction of the discrepancy at maturity, which in turn depends on vigorous assessment of the growth pattern exhibited in the past. This article reviews all of these factors.
