title: Congenital dislocation of the hip in boys.
abstract: Fifty-five boys with seventy-eight congenitally dislocated hips were treated between 1965 and 1990. The patients were divided into three groups according to the initial treatment. Group I included thirty hips (twenty-two boys) that had been treated initially with a Pavlik harness. Two hips (7 per cent) had a successful outcome, and twenty-eight (93 per cent) needed additional methods of treatment. Group II included forty-two hips (twenty-nine boys) that had been treated initially with closed reduction and immobilization in a hip-spica cast. After the closed reduction, twenty-nine hips (69 per cent) were considered stable, although fifteen (52 per cent) of them needed a secondary procedure because of residual subluxation or persistent acetabular dysplasia. Thirteen hips (31 per cent) were considered unstable after the closed reduction and subsequently had an open reduction. Group III included six hips (four boys) that had been treated initially with open reduction. Two of these hips redislocated after the open reduction, and they were reduced with an additional open reduction. A pelvic osteotomy was later performed to treat persistent acetabular dysplasia in these two hips. Two hips that had been treated with an open reduction and concomitant pelvic and femoral procedures did not need additional treatment. This study demonstrates that boys who have congenital dislocation of the hip do not always respond well to treatment and constitute a high-risk group.
