To investigate the surgical technique and efficacy of large retractor assisted maintenance of proximal femoral nail antirotation(PFNA) in the treatment of femoral intertrochanteric fracture in the absence of a retractor. ⋯ Large retractor assisted in maintaining the use of PFNA under reposition can fix various types of femoral intertrochanteric fractures. It has simple requirements for surgical position, low equipment requirements, short operation time, less trauma, reliable fixation, and good postoperative recovery. The surgical procedure can be carried out in a primary hospital without a traction bed.

To invstigate the influence of femoral neck area on larger anteversion angle of lag screw guide pin initial placement in proximal femoral intertrochanteric fracture treated with intramedullary nail. ⋯ The internal rotation of the affected limb and screw guide pin level may affect the anteversion angle of femoral neck when lag screw guide pin initial insertion, cause it to be too large and the screw guide pin level is the main influencing factor.
