BACKGROUND In an effort to decrease the rate of aseptic loosening, certain cemented femoral components were designed to have a roughened or textured surface with a methylmethacrylate precoating. Reports differ as to whether this step has increased or decreased the rate of failure. This study was designed to evaluate this issue. METHODS Five hundred and(More)
We present a case of a paravertebral abscess with extension into the hip joint. The presumed conduit of infection in this case is the iliopsoas bursa, which has been shown to provide direct communication between the retroperitoneal space and the hip joint in up to 15% of cadaveric specimens. The patient was treated with emergent open irrigation and(More)
In the study reported here, we evaluated 2-screw femoral neck fixation. Femoral necks from 5 paired fresh-frozen cadavers were fractured and then fixed with two 7.3-mm cannulated cancellous screws. Vertical (parallel screws in sagittal plane of femoral neck) and horizontal (parallel screws in superior aspect of femoral neck) configurations were used for(More)
Fractures of the hip in children have been associated with a very high rate of serious complications including avascular necrosis (up to 47%) and coxa vara (up to 32%). Over a period of 20 years, we have treated displaced fractures by early anatomical reduction, internal fixation and immobilisation in a spica cast to try to reduce these complications. We(More)
Surgical management of two-part and three-part proximal humerus fractures is difficult and requires familiarity with more than one method of fixation. Poor bone quality, comminution, and the deforming forces of the rotator cuff on the tuberosities influence the choice of operative approach and fixation techniques. Closed reductions and percutaneous pinning(More)
The articular surface of the normal humeral head has a variable posterior and medial offset with respect to the central axis of the humeral shaft. Recreation of the normal humeral head shaft offset is postulated to be an important consideration during shoulder arthroplasty. However, the effect of humeral head malposition is unknown. The purpose of this(More)
There has been some reluctance to perform total hip replacement on younger patients with osteonecrosis because of the poor results reported in the earlier literature. To determine the extent to which advances in surgical technique and prosthesis design have led to improved results, we evaluated 203 total hip replacements performed for osteonecrosis and(More)
BACKGROUND The purpose of this study was to evaluate the rate of recurrence and the prevalence of complications related to the use of thermal energy for the treatment of glenohumeral instability. METHODS A survey was conducted of all members of the American Shoulder and Elbow Surgeons, the Arthroscopy Association of North America, and the American(More)
BACKGROUND The purposes of this study were to describe the anatomical features of a rotational flap consisting of the clavicular portion of the pectoralis major and to report the surgical technique and the outcome of use of this flap in a patient with poor soft-tissue coverage following multiple operations for a clavicular fracture complicated by nonunion(More)
PURPOSE The purpose of this study was to review the results of a relatively homogenous group of patients with glenohumeral subluxation without labral pathology who were treated with an electrothermal capsulorrhaphy procedure. TYPE OF STUDY Case series without controls. METHODS From 1997 to 1998, 42 patients underwent electrothermal capsulorrhaphy using(More)
