Cure of the limp in children with congenital dislocation of the hip and ischaemic necrosis. Fifteen cases treated by trochanteric transfer and contralateral epiphysiodesis

Abstract

Fifteen patients who limped and had early fatigue on walking caused by ischaemic necrosis after treatment for congenital dislocation of the hip had distal and lateral transfer of the greater trochanter. Nine of them in whom the predicted leg-length discrepancy was more than 3 cm also had epiphysiodesis of the contralateral leg. At skeletal maturity the limp was eliminated and walking distance was significantly improved in them all. In those who had epiphysiodesis the average leg-length discrepancy was 0.7 cm at maturity. Two of those not treated by epiphysiodesis used a heel raise of 1.5 cm. In seven cases the two operations were performed simultaneously without serious complications. This procedure is recommended at about the age of 12 years.
