Objective To observe the effects and traits of applying locking anatomic plates to the proximal femur for the old-aged aroundtrochanteric fractures. Methods From January 2006 to August 2010, 56 cases with old-aged aroundtrochanteric fractures were selected as samples. Clinical and radiographic data were retrospectively reviewed at the 1st, 3rd, 6th, 12th month after operations. In the meantime, analysis of comparison between them and ones with the DHS treatment was conducted. Results All of the operations were successful. Altogether 56 patients were followed up, average 9.4 months. All of their fractures were healed in a mean time of 5.3 months without delayed union, nonunion, hip equinovarus, failure of screws and plates or death. Comparison of the excellent and goodrate of two groups, the dif-ferences was significant (P<0.05). Conclusion Applying locking anatomic plates to the proximal femur can provide sta-ble fixation with a good functional outcome, which is an effective method for the old-ageed aroundtrochanteric fractures and reducing death rate.
