Conservative treatment of the femoral head is mainly for mild necrosis of the femoral head, while other cases are best treated with surgery if they can tolerate it. Conservative treatment of necrosis of the femoral head is suitable for cases where the necrosis on the non-weight-bearing side is less extensive, the head shape is basically normal and there is extensive sclerosis. Conservative treatment mainly consists of protective weight-bearing, medication (NSAIDs such as celecoxib, anticoagulants such as warfarin, etc.), physical therapy, and rehabilitation exercises, and the use of medication should be under the supervision of a doctor. In other cases, if surgery can be tolerated, it is still recommended to try to surgical treatment. Surgery can avoid a series of complications associated with prolonged bed rest (e.g., venous thrombosis of the lower extremities, acne, etc.). The main types of surgery include core decompression, osteotomy, arthroplasty, and so on. Specific medications and treatments should be prescribed by a doctor.
