With the arrival of the aging society, there are more and more elderly patients with femoral neck fracture, which is a difficult fracture with a high rate of non-union and femoral head necrosis. Elderly patients are often bedridden after the injury, leading to complications such as pneumonia, deep vein thrombosis, cardiovascular and cerebrovascular disease, and even death. Artificial joint replacement is preferred for elderly femoral neck fractures to better restore hip function and avoid complications at the same time. However, traditional hip replacement surgery is very traumatic and requires disconnection of the important muscles around the hip joint, which makes it easy to dislocate the joint at an early stage and lead to failure of the surgery. In order to overcome this problem in the field of artificial joints, the director of orthopedics has been developing an innovative minimally invasive joint capsule repair hip replacement technology for many years and has achieved excellent clinical results. Six months ago, he took the lead in applying the latest Superpath minimally invasive technology for total hip replacement in the province. The surgical incision was reduced from 15 cm to 6-8 cm, and the hip joint was completely exposed through the muscle gap approach without disconnecting the periprosthetic muscles, which maximally protected the soft tissues and reduced surgical trauma. This greatly reduces the hospitalization cost and rehabilitation time, and significantly improves the quality of life of patients.
