We examined the cause of contractures in leg-lengthening for leg-length discrepancy in children.This report reviews 37 cases of leg-length discrepancy. Sixteen cases were due to hemihypertrophy, 14 cases of hemihypotrophy, 4 cases of congenital dislocation of the hip, 2 cases of trauma and one case with slipping of the upper femoral epiphysis.Important factors related to contractures were the interval of elongation each day and the daily rate of elongation length.The longer the daily interval of elongation and the higher the daily rate of elongation length, the greater the contracture.Gait and weight-bearing with a brace early in the post-operative period is useful for avoiding contractures.* Authors Note: Do you mean that the contracture seen in each case is more severe, or do you mean the incidence of contractures increases with increasing interval and rate of elongation.
