Femoral head necrosis is one of the common diseases in orthopedic clinics, and it occurs in young and middle-aged people. Its specific etiology and pathogenesis are complex and can be broadly divided into two categories: traumatic factors, such as femoral neck fracture and hip dislocation; non-traumatic factors, such as long-term use of hormones, excessive alcohol consumption, chronic liver disease, etc. Although their pathology is not completely consistent, the basic process of the disease is the necrosis of bone tissue and the subsequent repair reaction, and eventually the collapse of the femoral head and arthritis occur. The basic disease process is the necrosis of bone tissue and the subsequent repair reaction, and eventually the collapse of the femoral head and the appearance of arthritis. The usual clinical manifestation is pain in the groin area, which may radiate to the hip and knee. The pain can be constant or intermittent, and then gradually worsens, making it difficult to walk or even walk with crutches. When the above-mentioned symptoms appear, it is time to be alert. At this time, you can go to the hospital for X-ray, CT or even MRI to assist in the diagnosis. When taking X-rays, in addition to the orthopantomogram, you should also take a froggy lateral view to see more clearly. There are many ways to treat ischemic necrosis of the femoral head, and the key lies in correct diagnosis and staging. For early lesions, conservative treatment can be chosen, including avoidance of weight bearing, medication, physical therapy, Chinese medicine treatment, etc. Surgery can also be performed for medullary decompression, bone marrow stem cell injection, bone grafting, etc., with the aim of promoting bone repair and preventing joint surface collapse; in advanced stages of development, the joint surface collapses and produces hip arthritis with In advanced stages, the joint surface collapses, producing hip arthritis, and there is serious hip dysfunction, and then only joint replacement surgery can be performed to improve the function. For advanced patients, joint replacement is the only complete solution. Patients with bilateral femoral head necrosis usually require bilateral total hip arthroplasty. A large number of artificial hip replacement surgeries have been successfully carried out with mature technology. Integrating the leading technical strength and operating room conditions of our anesthesiology department, bilateral total hip replacement is routinely carried out at the same time, which can effectively reduce the treatment time and save costs, and is more conducive to the functional rehabilitation of the lower limbs with satisfactory results!
