The results of resurfacing or not resurfacing the articular cartilage of the patella were reviewed in 71 knees--47 with rheumatoid arthritis and 24 with osteoarthritis--which had been replaced with the ICLH prosthesis. Two rheumatoid and osteoporotic patellae developed transverse fractures with separation and were excluded from the review. The results(More)
PURPOSE OF THE STUDY The primary and secondary stability of a revision implant is highly compromised in cases with important loss of bone stock from the proximal femoral after severe femoral loosening. Several methods using implants with or without cement have been proposed for reconstruction after femoral bone loss. The purpose of this study was to analyze(More)
PURPOSE OF THE STUDY The purpose of this study was to assess clinical tolerance and radiological and histological changes observed after using a safe bovine xenograft (Lubboc) to fill open wedge defects after tibial osteotomy for valgisation in patients with medial femoro-tibial degeneration. MATERIAL AND METHODS Thirty-one valgus open wedge tibial(More)
Thirty revisions were performed on loose total hip replacements with a specific acetabular reconstruction technique combining the use of a bovine bone substitute and a support ring. One patient died of a cause unrelated to the procedure. No migration of the acetabular implant or bone lysis of the heterograft was seen in 27 cases after 3 years.(More)
This report is based on the study of 63 intertrochanteric flexion osteotomies of the hip with a ten-year follow-up. Every patient had severe osteoarthritis of the hip where abduction or adduction osteotomies could not possibly have recentered the femoral head in the acetabulum. The only alternative would have been a total hip arthroplasty. The reappearance(More)
PURPOSE OF THE STUDY The aim of this study was to report cases of acetabular failure of metal-on-metal total hip arthroplasties using cemented cups with a metal-metal bearing. MATERIAL AND METHODS From 1997 to 1999, 137 patients underwent total hip arthroplasty with a 28-mm head and a metal-metal (Metasul) bearing. At mean follow-up of three years eight(More)
PURPOSE OF THE STUDY The purpose of this study was to evaluate the 10-year results of the cemented Müller straight stem total hip prosthesis with polyethylene cup and 28 mm head. MATERIAL AND METHOD From May 1988 to May 1990, 187 cemented prostheses (second-generation technique) were implanted via a transgluteal approach for degenerative hip disease. A(More)
Authors report two new cases of oculo-dento-digital syndrome, besides the classical findings concerning the eyes, nose and upper extremities, they noted a relative shortening of the skeletal structure of the ocular maxillary region. This syndrome is thought to be an hereditary disease compatible with autosomal dominant inheritance.
