We followed 39 patients with 40 revision hip arthroplasties using the Wagner stem. Mean follow-up was 65 (29-108) months. There were 12 intraoperative proximal femoral fractures, which all united, five postoperative dislocations not related to subsidence, and two loose stems that were revised. Clinical improvement was best for pain. Once the stem was(More)
Between December 1995 and June 1996, we reviewed 53 consecutive patients who were at least 80 years old and had undergone a revision of a hip prosthesis between June 1988 and June 1995. Three patients (6%) had died after the operation in the hospital. Thirty-five patients were still alive with a mean follow-up of 4.0 years (range, 1.0-7.3 years). At(More)
In severe osteoporosis progressive collapse of multiple vertebrae is an unsolved problem. Medical treatment appears to be too slow to prevent the course. The evolving experience with vertebroplasty led us to treat these problems with more extensive cement injections. Of 362 patients who were treated with percutaneous cement injection over a 5-year period,(More)
A low hypoxic ventilatory response (HVR) has been observed in endurance athletes and has also been associated with low exercise ventilation and a high susceptibility to acute mountain sickness (AMS). In other studies, respiratory training was found to improve cycling endurance and decrease exercise ventilation. We therefore hypothesized that respiratory(More)
Lateral femoral insufficiency fractures in total hip arthroplasty occur due to osteopenia and varus positioning of the femoral component, the femur itself, or both. The presentation of these fractures can be unclear but usually involves the insidious onset of unexplained thigh or groin pain. The patients are likely to have significant comorbidities as well.(More)
168 fractures of the femoral shaft treated by intramedullary nailing were analyzed retrospectively. From 1986-1992 116 fractures had been treated with the reamed AO universal nail (RFN) and from 1993-1996 52 fractures with the AO unreamed femoral nail (UFN). In 24% of the RFN-group and in 2% of the UFN-group (p < 0.0001) open reduction of the fracture had(More)
Nailing of femoral fractures before closure of the growth plates may lead to avascular necrosis of the femoral head in 3-4% of cases. In addition to the 14 cases described in the literature we present 3 more. Analysis of these cases reveals a common pathogenesis. The nails were all inserted anterograde and were designed for the adult femur. The problem(More)
Monostotic fibrous dysplasia of the spine is a rare entity. Only 26 cases, of which 11 were located in the cervical spine, are to be found in the literature. We report a 56-year-old male patient with cervicobrachialgia of half year's duration. Radiographs showed a diffuse destruction of the vertebral body and the spinous process of C4. A biopsy of the(More)
