For patients with aseptic necrosis of the femoral head, rheumatoid hip arthritis and ankylosing spondylitis involving the hip joint, artificial total hip replacement surgery (THA) was generally used in the past. The traditional THA requires removal of the femoral head and neck, which results in a large amount of bone loss, and the artificial hip joint generally has a service life of 10 to 20 years, and when the time limit is up, another revision surgery will be performed. However, there are many younger patients, some of whom are even students, who suffer from hip disease. These patients should therefore be treated as minimally invasively as possible. The so-called minimally invasive approach is to preserve the maximum amount of the patient’s own bone. In recent years, an effective and minimally invasive method of treating hip disorders has been created, driven by the increasing development of medicine and material science, which is the artificial hip surface replacement surgery. This new procedure causes less trauma to the patient and, crucially, allows for maximum preservation of the patient’s femur, making it a truly minimally invasive procedure. The surgery is like putting a small cap on the femoral head without destroying the original anatomical form. The incidence of artificial joint dislocation after the surgery is low, the joint function recovers well, the patient avoids the pain of bone amputation, and it is easier to revise later. This new surgery is particularly suitable for young, active patients with early femoral head necrosis and congenital hip dysplasia. The prosthesis used in this procedure was approved by the FDA in the United States in 2006. We have accumulated rich clinical experience with this technology, and the results of the patient follow-ups have shown that the surgical efficacy is very accurate and the patients are satisfied. There are many hip diseases, including aseptic necrosis of the femoral head, osteoarthritis, rheumatoid arthritis, femoral neck fracture, ankylosing spondylitis, etc. These diseases are not only common among the elderly, but also have a high incidence among young people. The patient’s quality of life was poor and even lost the ability to work. With the development of science, advanced and minimally invasive techniques are now available to help patients get rid of their pain and return to society. It is important to raise the awareness of patients and doctors about the diagnosis and treatment of these diseases, so that early diagnosis and early treatment can be achieved.
