Severe femoral head necrosis, hip osteoarthritis and femoral neck fracture can only be cured by hip replacement surgery, but most patients have fear of hip replacement and are afraid of the surgery. Patients’ feelings are understandable, and doctors need to communicate more with patients and comfort them to dispel their worries. In recent years, Professor Wu Xing of the Department of Orthopedics of Shanghai Tenth People’s Hospital has introduced the latest foreign technology of minimally invasive hip replacement and achieved satisfactory results. Minimally invasive hip joint replacement surgery is a new advanced technology developed internationally in recent years, featuring small surgical incision, less blood loss, short hospital stay and quick recovery. Since 2010, Wu Xing and other professors of the Tenth People’s Hospital have introduced this advanced technology, modified the surgical access and surgical instruments required, and standardized the entire operation procedure, achieving very satisfactory treatment results. The incision length of our hip replacement surgery is only about 7-8cm, which is much lower than the international orthopedic requirement of less than 11cm for minimally invasive hip replacement surgery. The hip muscles are protected to the greatest extent during the operation, and the muscles are accessed through the muscle gap through a modified lateral incision, instead of the traditional posterior lateral incision to cut the muscles. Postoperatively, the patient felt light pain and could be on the ground 3 days after surgery, with good preservation of hip muscle strength. The minimally invasive hip replacement technique also significantly shortens the time of postoperative recovery. In the majority of our patients, the patients were discharged from the hospital one week after surgery with excellent recovery of joint function. The use of minimally invasive hip replacement technology can effectively shorten the surgery time, with our fastest hip replacement surgery taking only 30 minutes. Minimally invasive hip replacement surgery can also significantly reduce the amount of intraoperative bleeding and the chance of transfusion of allogeneic blood, which is usually about 100-150 ml.
