title: [Bipolar endoprosthesis in fractures of the femoral neck. Apropos of 201 cases, 116 after a 6-year follow-up].
abstract: We report our experience with 201 SEM bipolar prostheses used to treat femoral neck fractures in patients with a mean age of 70 years and a mean follow-up of 57 months (median 75 months). Clinical outcome was favorable with 94 per cent satisfactory results (very good and good). Femoral complications requiring reoperation (conversion to total hip replacement) occurred in 2.2 per cent of cases. Among the 163 patients for whom roentgenographic data were available, 5 (3.6 per cent) developed evidence of acetabular wear but remained symptom-free and did not require reoperation. As compared with Moore's prosthesis, the SEM bipolar prosthesis seems to provide substantially better clinical and roentgenographic results. For the treatment of femoral neck fractures, total hip replacement seems to provide results comparable to those reported here but requires a more sophisticated operative technique and carries a greater risk of subsequent dislocation. Two factors prevent the widespread use of the bipolar prosthesis at present: the need for femoral grouting which carries a well-documented risk of hemodynamic complications, and the higher cost of the device.
