Acetabular fractures are the high point in orthopedic fracture healing, and complex acetabular fractures are very difficult to operate on and have relatively poor surgical results. The acetabulum is the part of the hip joint that matches the femoral head and is called the acetabulum. Acetabular fractures are often the result of relatively massive violence or fall injuries or car accidents, and are more difficult to treat with high risk because when disease occurs, when such fractures occur, they are often relatively large injuries, combined with abdominal or thoracic or cranial trauma, so the risk is higher. Because the acetabulum is an articular surface fracture, surgery is the only method. There are so many accesses to surgery to treat an acetabular fracture, each of which is relatively large, and it is difficult to ensure complete recovery of the articular surface. Often, a combination of anterior and posterior approaches is required to restore the acetabulum to a better position. So the cause of the injury itself decides to combine with other very serious concurrent injuries of other systems, plus the surgical blow, and the bleeding itself is relatively large, which is a big change for the body and a huge blow to all aspects of the circulatory system, so the acetabular fracture is very risky.
