Acetabular coverage after innominate osteotomy.

A criticism of innominate osteotomy is that it may cause relative acetabular retroversion, predisposing to osteoarthritis. This study was designed to address that hypothesis. We had access to standing hip radiographs of 30 patients (36 hips) who had undergone open reduction and innominate osteotomy for late presenting developmental hip dislocation at least 40 years earlier.

Outcome at forty-five years after open reduction and innominate osteotomy for late-presenting developmental dislocation of the hip. Surgical technique.

Background: A consecutive series of seventy-six patients (101 hips) underwent primary open reduction, capsulorrhaphy, and innominate osteotomy for late-presenting developmental dislocation of the hip. They were between 1.5 and five years old at the time of surgery, which was done between 1958 and 1965.

Outcome of Copeland surface replacement shoulder arthroplasty.

We report the outcome of humeral head surface replacement hemiarthroplasty performed at our institution using the Copeland prosthesis. We followed 56 shoulders (52 patients) for a mean of 34.2 months (range, 24-63 months).

Geometrical analysis of Copeland surface replacement shoulder arthroplasty in relation to normal anatomy.

This study examines the effect of humeral head surface replacement on the geometry of the arthritic glenohumeral joint and correlates changes to clinical outcome. Thirty-nine patients undergoing resurfacing arthroplasty were prospectively followed up clinically and radiologically for a mean of 38 months (range, 24 to 72 months). Measurements were taken from coronal radiographs by use of a validated technique.
