Total hip replacement has the advantage of a long life of the artificial joint, and hemi hip replacement has the advantages of low cost, less trauma, and more tolerable surgery, so it is not possible to specify whether femoral head replacement is better for the total hip or the hemi hip. The choice needs to be made according to the patient’s specific situation. Total hip replacement is to replace both the femoral head and the acetabulum with artificial ones. This method has a stronger resistance to wear and tear of the hip joint and a relatively longer use time, but the surgery is traumatic, time-consuming and expensive. It is generally used for patients under 70 years old with good bone quality or femoral neck with acetabular injury. Hemiarthroplasty is to replace the femoral head, the acetabulum is still retained and continue to use, this method of surgery is relatively less traumatic, shorter, easier to tolerate, relatively low cost, but due to the relatively poor abrasion resistance of the acetabulum, so after a few years or more than ten years need to consider replacing the artificial hip joint, so it is generally used for patients aged 70 years old and above, or patients with relatively poor tolerance of surgery. The specific choice of surgery is recommended to visit the hospital and choose under the advice of the doctor.
