There are relatively many types of internal fixation for femoral neck fractures, and in clinical practice, hollow compression screws are often used. This type of internal fixation requires the use of a C-arm after traction repositioning on a traction bed to confirm a good position, and then only a very small incision needs to be made, and three hollow compression screws in a zig-zag shape are driven in for fixation. In addition, less common internal fixations in the clinic are power hip plus anti-rotation screw fixation, and PFNA internal fixation. If the patient with a femoral neck fracture is relatively old, such as over 65 years of age, it is estimated that aseptic necrosis of the femoral head may be present or that osteoporosis is relatively more severe, total hip arthroplasty may be used to treat the femoral neck fracture.
