Primary total hip arthroplasty with a flattened press-fit acetabular component in osteoarthritis and inflammatory arthritis: a prospective study on 416 hips with 6-10 years follow-up.

Introduction: A flattened cup was designed to create a more physiological load transfer to the pelvic bone compared to hemispherical cups, and to allow more bone contact compared to low-profile' spherical cups. To investigate these theoretical advantages and the potential influence of the quality of the acetabular bone, a clinical study was performed in patients with osteoarthritis (OA) and inflammatory arthritis (IA). The aims of the study were (1) to evaluate the fixation of the cup, postoperatively and later when osseous integration should have taken place, (2) to assess perioperative complications such as acetabular fractures and (3) to monitor the polar gap, a potential risk factor for osteolysis.

Scarf osteotomy in hallux valgus: a review of 72 cases.

The Scarf osteotomy is now widely used for the correction of hallux valgus. The aim of our study was to evaluate the results after Scarf osteotomy considering patient's satisfaction as well as the clinical and radiological results. Between 1996 and 1999, 72 feet underwent a Scarf osteotomy of the first metatarsal and, in 11 feet, an additional Akin osteotomy of the proximal phalanx, for the correction of hallux valgus (55 patients: 49 female, 6 male; mean age: 52 years).

Tendoscopy of the posterior tibial tendon.

Posteromedial ankle complaints are most often caused by a disorder of the posterior tibial tendon. Two predominant groups of patients can be distinguished: the first involves younger patients who have some form of systemic inflammatory disease; the second involves older patients whose dysfunction is caused by chronic overuse. This article illustrates endoscopy of the posterior tibial tendon in a group of patients who had diverse pathology.
