Abstract BACKGROUND: The continuous increase in the number of fractures of the proximal femur is directly attributable to the worldwide increase in life expectancy. The standard version of the Gamma Interlocking-Nail (standard Gamma nail [SGN], 200-mm length, 10-degree valgus curvature, two distal locking bolts) was designed because of the demands in orthopedic hip surgery to develop an implant stable enough to mobilize old patients as soon as possible to avoid further morbidity and mortality. METHODS: Between the years 1992 and 1998, 1,000 consecutive patients with peritrochanteric fractures were stabilized by using the SGN and included in this study. Special emphasis was given to the evaluation of the learning curve of the department of traumatology (not of single surgeons) and the influence of prognostic factors on the outcome of such operations. RESULTS: The results of this study show that increasing "department experience" resulted in a reduction of the intraoperative complication rate by a factor of 0.5 (p = 0.0001) per year. This means that even an inhomogeneous mass of 78 surgeons can lower the rate of intraoperative complications by 50\% per year because of increased experience. The number of early postoperative complications annually decreased by a factor of 0.8 (p = 0.0042). CONCLUSION: Late postoperative complications correlate negatively with the patient's age (odds ratio, 0.9; p = 0.0001).
