Summary

Dislocated femoral neck fractures are routinely treated with cemented hemiartroplasty and the direct lateral approach (Hardinge) has commonly been used in Norway. The investigators have lately witnessed a significant change in the prefered surgical approaches in total hip arthroplasty (THA) in favor of the posterior and anterior approaches. The direct lateral approach has in THA, more or less, been abandoned in Norway. Numerous studies have reported superior results using the posterior and anterior approahes compared to the lateral approach.
