Functional Anatomy of the Hip Joint Specific to THA

Understanding the origin and function of the periprosthetic muscles and neurovascular system is important in total hip arthroplasty (THA) from the viewpoint of the use of retractors and implant placement techniques and prevention of complications, such as dislocation and neurovascular injury. The hip joint’s anatomy can be easily understood by dividing it into anatomical parts based on its deep structures. The location and names of intraoperative landmarks in bone morphology and the structure and function of intra-articular joints and joint capsules, deep and shallow muscles, tendons, and neurovascular routes must be understood.
