Conversion arthroplasty of the hip: mid-term results are good.

The historical mid-term results of conversion total hip arthroplasty (THA) are acceptable; however, the complication rates are high. In total, 39 patients (45 hips) from 2 institutions underwent conversion THA from 1993-2006 and were retrospectively evaluated. The mean age was 48.

Total hip arthroplasty with acetabular reconstruction using a bulk autograft for patients with developmental dysplasia of the hip results in high loosening rates at mid-term follow-up.

Purpose: Managing a deficient acetabulum in patients with developmental dysplasia of the hip (DDH) can be challenging. The purpose of the study was to determine the mid-term results of total hip arthroplasty (THA) using a bulk structural autograft for reconstruction of the acetabular roof in patients with DDH.

Methods: Between 1982 and 1999, 112 patients underwent THA with acetabular roof-plasty using a bulk structural autograft for secondary osteoarthritis related to DDH.

[Case of a young woman successfully operated on for acute pulmonary embolism and right ventricular thrombus after urogenital infection].

The authors report a case of a 22-year-old women operated on for pulmonary embolism with success. The venous embolism developed in two phases one week apart. The first clinical sign was a dyspnea of abrupt onset limiting physical activity even after a mild exertion.

Intraarticular osteoid osteoma: clinical features, imaging results, and comparison with extraarticular localization.

Objective: Intraarticular osteoid osteoma is uncommon and presents diagnostic difficulties, which are important for both rheumatologists and orthopedic surgeons. Clinical symptoms, imaging procedures, differential diagnostic problems, and treatment results of intraarticular as compared with extraarticular osteoma are analyzed in this retrospective study.

Methods: Nineteen patients with intraarticular osteoid osteomas (Group A), with a mean followup period of 34 months, are compared with 15 others with extraarticular lesions (Group B).
