Bipolar hemiarthroplasty in degenerative arthritis of the hip. 100 consecutive cases.

This retrospective study represents the authors' experience with bipolar hemiarthroplasty in 100 consecutive patients with degenerative arthritis. Seventy of 100 patients were available for follow-up assessment. Mean follow-up interval was 4.

Experience with the bipolar prosthesis in hip arthroplasty. A clinical study.

Hip arthroplasty using a bipolar prosthesis was performed in 73 patients (75 hips) with femoral neck fracture, osteoarthritis, rheumatoid arthritis, or degenerative arthritis. Bipolar hip arthroplasty is more conservative than conventional total hip arthroplasty, because methyl methacrylate usually is not needed to fix the bipolar prosthesis to bone. Overall results were 67.

Varus injury of the knee with common peroneal nerve palsy.

Extensive lateral ligamentous disruption of the knee, otherwise known as severe varus or adduction strain, and common peroneal nerve traction injury (neuropraxia), or complete nerve transection, are rare injury complexes. Six patients with this type of knee injury were studied. Their cases and follow-up, most spanning many years, are reported in detail, with special attention to common peroneal nerve recovery.

Treatment of trochanteric fractures with Ender rods.

The technical aspects of Ender's method in the treatment of trochanteric fractures are described. Problems and complications encountered with this method and their prevention and treatment are discussed. Intraoperative and postoperative problems are subdivided into those in the hip area and around the knee joint, such as: varus deformity, protrusion of the rod medially or laterally or into the hip joint, cracking the distal femur, incorrectly placing the window on the anteromedial side of the femoral condyle, backing out of the rods, and supracondylar fractures.
