4、hods: Twenty-three patients for intertrochanteric fractures were treatment with PFNA. To observe the fracture healing and the function recovery. Results: 23 cases were all followed up from 4 months to 14 months after operation. The all of 23 patients with fracture were healing. According to Harris s
