Fractures of the proximal femur in the elderly population are rising. Teaching the appropriate surgical treatment of these fractures is of paramount importance. The aim of the study was to evaluate differences in outcome of surgical procedures between supervised trainees and senior surgeons. Are there more surgical complications, poorer quality or an increased operating time if the procedure (in this case: fixation of proximal femur fractures) is performed by trainees under supervision in comparison to experienced surgeons. All patients treated with the proximal femur nail antirotation (PFNA) between 2015 and 2016 at a level one trauma centre were included in this study. The retrospective review of the 299 patients compared supervised surgical trainees and senior surgeons. Parameters included operating time, tip apex distance, position of the blade, Hb-difference, transfusion rate, surgical complications as well as mortality, and were compared between the groups. 153 of 299 procedures were performed by supervised surgical trainees. In comparison to senior surgeons, there was no significant difference in operating time (WA 54.48 min; OA 60.47 min; p > 0,05), Hb-difference (WA 2.8 g/dl; OA 2.6 g/dl; p > 0.05), tip-apex distance (WA 21.2 mm; OA 20.5 mm, p = 0.37) or rate of surgical complications. There was no difference in the rate of optimal blade positions between the groups (WA 87.5%; OA 89.0%; p = 0.366). Furthermore, mortality showed no difference between the groups, but was greater in older patients or high ASA grade. Supervised surgical training during treatment of proximal femur fractures shows no increase in operating time, complications or mortality and no difference in quality. With the fast growth of the elderly population, surgical training of fragility fractures should receive more attention in the future.
