Since the establishment of the orthopaedic unit of the joint sports department in the Gliding Hospital in January 2010, a large number of patients with femoral neck fractures requiring artificial hip replacement and intertrochanteric fractures requiring Proximal Femoral Nail Anti-rotation (PFNA) treatment have been admitted. The treatment results were satisfactory. These patients are of advanced age (mostly over 80 years old), with more underlying diseases and poor surgical tolerance, thus requiring higher surgical technique and perioperative treatment. Hip arthroplasty and PFNA treatment of intertrochanteric fractures have become one of the routine treatments for these patients in the department. Among them, the department has improved the artificial hip joint replacement into a small incision surgery, with an incision length of about 6-8 cm, and only part of the external rotator muscle is cut off during the operation. Because of its easy operation, short operation time, less bleeding and less injury, many elderly and frail patients with poor cardiopulmonary function can also tolerate the operation. Compared with traditional surgery, PFNA does not require high stability of the fracture, its shear resistance is better, its fatigue resistance is increased, its stability can meet the patient’s early active and partial weight-bearing needs, and the operation time is shorter, which is a more suitable treatment for elderly patients.
