We measured the dimensions of the humeral and glenoid articular surfaces in 140 shoulders that were representative of a given population of patients, and also evaluated several glenohumeral relationships. Ninety-six measurements were made in the shoulders of cadavera and forty-four, on magnetic resonance-imaging studies of living patients. Eighty-five per(More)
Between 1983 and 1986, 40 hip arthroplasties in 40 patients with documented deep infection were reimplanted using Palacos Gentamicin at The Hospital for Special Surgery. Palacos Gentamicin was added to the standard protocol, which included removal of the prosthesis, cement, if present, and a thorough debridement of infected and necrotic tissue, six weeks of(More)
A retrospective study was performed evaluating the results of three different intraoperative culture techniques and their diagnostic value in determining clinical infection in patients after a total joint replacement. Twenty-four patients (34 cases) met the selection criteria and were evaluated using intraoperatively collected tissue samples, swab samples,(More)
Long-term follow-up of early Charnley cemented THAs demonstrates excellent survival (Table 1). New techniques in cementing have improved the quality of the femoral cement fixation and have shown consistently good performance at 10-year follow-up. Noncemented designs have not yet demonstrated similar long-term results. Recent reports reveal osteolysis in(More)
The versatility of modular total hip arthroplasties have rapidly extended their applications. However, these new interfaces can lead to complications that were not observed with monolithic components. These problems have been noted with modular femoral and acetabular components and have been associated with the generation of particulate debris. This article(More)
We reviewed 19 revision hip arthroplasties in which the new femoral component had been recemented into the old, intact cement mantle. The mean time from the first operation to revision was 64 months and the average follow-up was 59 months. There were 7 excellent, 11 good, and one fair result. No femoral component had been revised for loosening and all the(More)
Total hip arthroplasty is a common technique for the surgical management of degenerative hip disease. Because of the increasing number of patients and the variety of prostheses and fixation modalities available to the surgeon, the evaluation of the patient with a painful arthroplasty has become an increasingly complex endeavor. The growing number of(More)
Investigation of the death of a 77 year old woman from acute hepatitis B infection revealed that she had undergone orthopaedic surgery two and a half months earlier. The surgeon was found to be a hepatitis B surface antigen carrier, hepatitis B e antigen (HBeAg)negative, but with antibodies to HBeAg. Viruses from the surgeon and the patient were identical,(More)
The synthesis of model porous metal-CPC materials, and their use in one-parametric studies of bone tissue ingrowth enhancement were considered. By using the same starting calcium-deficient hydroxyapatite powder, three different coatings, CAP1, CAP2 and CAP3, were obtained of thicknesses 50 +/- 5, 75 +/- 5 and 75 +/- 5 microns, respectively. CAP1 and 2 were(More)
The cost of the prosthetic components can represent approximately 15% to 25% of the total cost of hospitalization, depending upon whether cemented or cementless fixation is selected. The excellent long-term clinical data of cemented fixation and the cost of the implants clearly favor cemented fixation for total hip arthroplasty in the elderly patient.
