The acetabular fracture is mainly located in the hip joint, which is where the groin is located. The normal acetabulum is wrapped around the femoral head and forms the hip joint, which is hemispherical and deeply concave, with a diameter of about 3.5 cm, and together with the femoral head forms the hip joint. There are two acetabulae on the left and right side of the body that are symmetrical. The inner side of the acetabulum is the pelvic cavity, which mainly includes the rectum, urethra and reproductive system, along with a large number of blood vessels and nerves passing around. Acetabular fracture is a fracture of the pelvis involving the articular surface, and a displacement of more than two millimeters requires further surgical repositioning and fixation to maintain the stability of the articular surface, and the current surgical methods are mainly incisional internal fixation and minimally invasive closed repositioning internal fixation, minimally invasive closed repositioning internal fixation is less invasive and has fewer postoperative complications, which is a popular treatment method to restore the anatomical position and stability of the articular surface of the acetabulum through surgical fixation. It is a popular treatment to restore the anatomical position and stability of the acetabular joint surface through surgical fixation, and to avoid the prognosis of traumatic arthritis causing pain during walking.
