γγThe common approaches are: 1, posterior lateral approach: the patient usually operates in the lateral position, the surgical incision is located in the hip, usually 18-700px long, the gluteus maximus, external rotators and other muscles need to be separated or cut to reveal the hip joint to complete the surgery, the chance of posterior dislocation is relatively high compared with other approaches; 2, lateral approach: the patient operates in the lateral position, the surgical incision is located in the lateral part of the hip, usually 15-500px long, the risk of posterior dislocation is relatively small; 3, anterior approach: this approach is becoming popular internationally, especially in North America. 3.Anterior approach: This approach is becoming popular internationally, especially in North America, where the patient is operated in the supine position and the surgical incision is located in the front, longitudinal or transverse, about 8-300 px long, without cutting any muscle tissue, and the operation is completed from within the muscle gap, with less risk of dislocation and faster recovery.γγ4.Other approaches: such as OCM approach, small posterior incision, double incision approach, etc., have relatively few users and have their own advantages and disadvantages.
