BACKGROUND Factors predisposing to tearing of the rotator cuff are poorly understood. We have observed that the acromion of patients with a rotator cuff tear very often appears large on anteroposterior radiographs or during surgery. The purpose of this study was to quantify the lateral extension of the acromion in patients with a full-thickness rotator cuff(More)
We hypothesised that a large acromial cover with an upwardly tilted glenoid fossa would be associated with degenerative rotator cuff tears (RCTs), and conversely, that a short acromion with an inferiorly inclined glenoid would be associated with glenohumeral osteoarthritis (OA). This hypothesis was tested using a new radiological parameter, the critical(More)
BACKGROUND The natural history of massive rotator cuff tears is not well known. The purpose of this study was to determine the clinical and structural mid-term outcomes in a series of nonoperatively managed massive rotator cuff tears. METHODS Nineteen consecutive patients (twelve men and seven women; average age, sixty-four years) with a massive rotator(More)
BACKGROUND Glenoid loosening continues to be the primary reason for failure of total shoulder arthroplasty. The purpose of this study was to evaluate, with use of a sensitive and reproducible imaging method, the radiographic and clinical results of total shoulder replacement with a pegged, cemented polyethylene glenoid implant. METHODS Forty-three(More)
PURPOSE Leg length discrepancy and angular deformities can, in contrast to adults; easily be corrected with epiphysiodesis during growth. Goal of this study was to evaluate our results of a modified Canale technique for definitive epiphysiodesis treating leg length discrepancy and also angular deformities. METHODS Between 2000 and 2007, 22 patients (11(More)
BACKGROUND Reverse total shoulder arthroplasty allows the restoration of active overhead elevation in patients with a massive rotator cuff tear and pseudoparesis of elevation. However, it does not restore active external rotation, the lack of which can also constitute a substantial functional handicap and compromise the outcome of this arthroplasty.(More)
BACKGROUND Static posterior subluxation of the humeral head (PSH) is often associated with glenohumeral arthritis. It may persist following total shoulder arthroplasty (TSA) and lead to accelerated polyethylene wear and glenoid component loosening. The factors which lead to PSH are poorly understood. The purpose of this study was to test the hypothesis that(More)
We report a new technique for pelvic external fixation that we have developed as an alternative to the anterosuperior (Slätis) and the anteroinferior (supra-acetabular) type pelvic external fixator configurations. The method principally differs from the other techniques by virtue of the subcristal positioning of the pins and offers advantages in terms of(More)
BACKGROUND Keller-Brandes resection arthroplasty for correction of symptomatic hallux valgus deformity can obtain early good results, but late complications, such as recurrence of the deformity and instability of the first ray, have been described. Arthrodesis of the first metatarsophalangeal, (MTP) joint can be done as a salvage procedure. The aim of this(More)
We compared six patients with a mean age of 70 years (49 to 80) with severe bilateral, painful glenohumeral joint destruction who underwent a single-stage bilateral total shoulder replacement, with eight patients of mean age 61 years (22 to 89) who underwent bilateral total shoulder replacement in two stages, at a mean interval of 18 months (6 to 43). The(More)
