[Impacted femoral neck fracture, surgery or not?]

Osteosinthesis of femoral neck fractures achieves higher stability of fragments but additionally destroys weak vascular elements of femoral neck. Aim of this study is to analyze relation between different treatment options of impacted femoral neck fracture and avascular necrosis of femoral head. In retrospective analysis we have retrieved data from 1632 patients who were treated at the Department for traumatology, Clinical center Ljubljana in period Jan/87 - Dec/01. Impacted femoral neck fracture was found in 365 patients (22.4%). We have selected only patients with follow up period longer then half year and finally there were only 94 patients included in study. Analyzing incidence of avascular necrosis, dislocation of fragments, and pseudoarthrosis in non-operatively and surgically treated groups of patients by lambda2 (0.305), we have concluded that there is no relation between avascular necrosis and way of treatment of impacted femoral neck fracture.
