[Strategies for complications prevention and management of complex total hip arthroplasty]

Although the complications of complex total hip arthroplasty (THA) are decreasing with the progress of surgical technology, it is still a difficult clinical problem. Complex THA has a high risk of dislocation, vascular and nerve injury due to anatomical disorder, poor soft tissue condition, bone defect and other factors. Recent studies have shown that spinal-pelvic linkage, soft tissue protection and reconstruction, and the removal of impingement potential factors play an important role in maintaining hip joint stability. Minimally invasive interventional therapy has become an important means to deal with main vascular injury. There are still no clinical guidelines for the diagnosis and treatment of nerve injury, but in recent years, the principle of comprehensive management based on prevention has gradually been paid attention to. In the future, with the development of artificial intelligence(AI), AI-assisted preoperative planning and robot-assisted technology will be widely used in complex THA, which is expected to further improve the accuracy of surgery and reduce the risk of complications.
