The acetabular response to proximal femoral varus rotational osteotomy. Results after failure of post-reduction abduction splinting in patients who had congenital dislocation of the hip.

The acetabular response to proximal femoral varus rotational osteotomy was studied radiographically in twenty-eight patients who had had thirty-three congenitally dislocated hips. All of the patients had previously been managed with open or closed reduction followed by use of a spica cast and had worn an abduction orthosis for at least one year after the reduction. The indications for the femoral osteotomy were a persistently increased acetabular index or subluxation, or both.

Fractures after Wagner limb lengthening.

A retrospective review of our experience with fractures after 27 Wagner limb lengthenings (23 patients) was undertaken. Ten fractures occurred after lengthening in eight patients (six spontaneous, four traumatic). Seven patients fractured despite a "staged" removal of the fixation plate.
