Experience with Legg-Calvé-Perthes disease (LCPD) 1968--1974 at the New York Orthopaedic Hospital.

Of 19 patients (24 hips) with LCPD treated between 1968 and 1974, 18 hips were treated by nonoperative methods (the abduction weight-bearing program as described by Petrie), and six hips were treated by Salter innominate osteotomy. Using Catterall's classification of the roentgenographic changes, 14 cases were rated good; 4 were fair and 6 were poor. The age at the time of diagnosis was the most reliable diagnostic parameter.
