Congenital hip dislocation or dysplasia with subluxation: a radiologic study.
We studied the behavior of hips in congenital hip dislocation. Two types were identified: those that developed normally after closed reduction and those that required an osteotomy. Children with hips that required an osteotomy were older at presentation and at follow-up had worse subluxation, with shallower acetabula. In this group, the younger the age at which reduction was achieved, the less the residual subluxation of the hip at follow-up. The age at which the late osteotomy was performed did not appear to affect the residual hip subluxation or the acetabular development. We could not find any radiologic parameter that would predict the need for an osteotomy.
