Course of bone mineral content changes around cementless Zweymueller total hip arthroplasty. A 4-year follow-up study.

In this prospective study we followed the bone mineral content (BMC) changes over time in seven zones of interest around uncemented Zweymueller total hip arthroplasty (THA) components, using dual-energy X-ray absorptiometry (DEXA) combined with a radiographical analysis of the distal femoral cortices, close to the tip of the stem. In 36 women (average age 55 years) operated on for primary hip osteoarthritis, BMC of the hips was measured preoperatively and 2 weeks, 1 year and 4 years postoperatively. In particular, a significant decrease of the preoperative values (ranging from 35% to 42.

Acute osteomyelitis of the patella 50 years after a knee fusion for septic arthritis. A case report.

Nontraumatic, hematogenous osteomyelitis of an unfused patella occurred in a 62-year-old female patient, 50 years after septic arthritis of the knee was treated in childhood by femorotibial fusion. This extremely rare condition was successfully treated by a patellectomy, continuous irrigation, and antibiotics. This occurrence seems not to have been reported previously in English literature.

Anterior dislocation of the hip associated with fracture of the ipsilateral greater trochanter. A case report.

A 22-year-old male motorcyclist fell from a height and sustained an obturator hip dislocation with concomitant fracture of the ipsilateral greater trochanter. The immediate reduction of the dislocation associated with open reduction of the fracture of the greater trochanter showed excellent results at the short-term and long-term follow-up examinations. This extremely rare hip injury seems not to have been previously reported in the literature.
