title: [Clinical application of gamma nail in the treatment of the intertrochanteric fractures].
abstract: We retrospectively studied the clinical application of modified Gamma nail (GN). Based on the measurement of intramedullary canal of the femur by wax model. We modified GN in the following aspects: the diameter of GN was changed from 17 mm to 14 mm in the proximal end and from 13 mm to 10 mm in the distal end and the angle between the two ends was also modified from 11 to 5-6; the modified compression screws represented self-compression property; the long GN was designed and developed. We applied GN in 31 cases, and 28 with an average postoperative duration of 20 months were followed up. The final results revealed that the fracture healing rate was 93%. No crutch ambulance reached 86% and excellent hip movement reached 82%. The partial or complete weight bearing was allowed 9-11 days postoperatively. We consider GN an effective means for the treatment of type II and type III of intertrochanteric fracture of the femur.
