title: [Medial femoral neck fractures treated with hip compression screw. A product control study].
abstract: 311 medial femoral neck fractures (213 of them displaced) treated with a hip compression screw were studied retrospectively. 90 patients were treated with a primary hemiprosthesis during the same period. Fixation was lost in the case of seven fractures within three months after the operation. Two patients developed pseudarthrosis and 53 late segmental collapse. 54 patients have been reoperated, and given an endoprosthesis. The radiographs of 176 patients (114 displaced fractures) who were accessible for follow-up until failure, or for at least three years, were analysed. The rates of late segmental collapse were particularly high for fractures with a postoperative anterior angulation exceeding 15 degrees. Displacement and time until operation were independently related to late segmental collapse.
