[Surgical treatment of proximal femoral fractures--a training intervention?]

Proximal femoral fractures are common in the elderly. Surgical and postoperative complications are of major importance in this population. Numerous factors affecting the treatment results could be identified so far. The effect of surgeons' experience in terms of educational status is not entirely clarified yet. The aim of the present study was to analyse the effect of surgeons' educational status on the outcome in proximal femoral fractures. Therefore treatment results were compared in terms of individual surgeons' experience. Furthermore, the surgical education concept of our department was evaluated.

At a national trauma centre, patients of at least 60 years of age with proximal femoral fractures were prospectively screened. Patient-specific parameters like Barthel index, ASA score, Charlson score, patients' age and type of fracture were collected at the time of hospital admission. During the in-hospital stay type of fracture treatment, surgery time, number of blood transfusions, perioperative complications, duration of in-hospital stay as well as in-hospital mortality were recorded. Results were analysed for osteosynthesis and prosthesis depending on the surgeons' educational status. Four different groups of surgeons were distinguished (inexperienced senior house officer; experienced senior house officer; specialist in orthopaedics and accident surgery; specialist in orthopaedics and accident surgery with an additional qualification for special accident surgery).

402 patients with coxal femoral fractures could be included into the study. 160 patients (40 %) sustained complications of different severity. In-hospital mortality was shown to be 6.2 %. Separate consideration of osteosynthesis and prosthesis revealed no difference between the four groups of surgeons regarding mortality rate, number of blood transfusions and in-hospital stay. In terms of cutting/suture time consultants with a further specialisation in trauma surgery were significantly faster.

Apart from cutting/suture time, surgeons' educational status had no statistically significant impact on the rate of complications, rate of blood transfusions, hospital mortality and in-hospital stay. It can be presumed that surgical education according to our educational concept has no negative effects on treatment quality of patients with proximal femoral fractures. Differences in cutting/suture time give a hint for the additional expense that is connected with surgical education.
