title: Transposition of the great trochanter in the treatment of congenital dysplasia of the hip and Perthes disease.
abstract: The authors report their results in 17 hips treated by distal transposition of the great trochanter in patients suffering from coxa vara resulting either from congenital dislocation of the hip or Perthes disease. The results, evaluated both clinically and radiologically, were excellent. We would emphasize that distal transposition inevitably implies lateralization, which restores the normal musculo-skeletal relationship. The "hyperlordosis" sign is described and its mechanism explained. This simple physical sign is a useful test in evaluating the indications for this type of operation.
