Variations in the treatment of medial fractures of the neck of the femur were investigated by means of a questionnaire sent to all hospital departments which operated on these fractures. 91% replied. 86% of the departments used thromboembolic prophylaxis as a routine and 24% employed prophylactic antibiotics. Operation was only performed prophylactically on cases of impacted fractures in 24% of the departments. Orthopaedic departments operated earlier and more frequently preferred cancellous bone screws as the method of osteosynthesis rather than a sliding screw plate. The latter method was preferred by the non-orthopaedic departments. Patients were mobilized earlier in the orthopaedic departments and fewer postoperative x-rays were taken than in the non-orthopaedic departments.
