Although the efficacy of various surgical treatments to preserve the femoral head continues to improve, a significant percentage and number of cases of ischemic necrosis of the femoral head will progress to the point of requiring an artificial joint replacement. Surgery carries certain risks, and although artificial joint replacement is a mature procedure, there are still some potential surgical risks, just like any other surgery. Some patients don’t want to have surgery so soon and want to put it off as long as possible, and some people think there is no risk if they don’t have surgery. In fact, not having surgery is not completely free of problems. 1, because the femoral head necrosis will be painful, making it difficult for the patient to walk, or walk poorly, will obviously affect the quality of life; 2, long-term, the bone of this side of the femoral head necrosis due to reduced limb activity may be loosened, bone a loosening, when you want to do surgery, joint replacement surgery effect may be discounted; 3, the joint lesion if it reaches a very serious degree, the entire joint formed The difficulty and complexity of the surgery will increase if osteoarthritis and joint deformation are severe. And the leg may be shortened, affecting the walking gait, which will also increase the difficulty of surgery; 4. If one side is in pain, the body will adjust, transferring some strength to the other side, which will increase the burden on the other limb, the femoral head, then the original good joint may also have problems under such great pressure; 5. Femoral head necrosis may also affect the spine, because after this lesion occurs, it may It will cause shortening or pain, the waist will not be straight, but will be some tilt, long-term may also have a negative impact on the spine. 6, due to pain long-term use of painkillers, long-term use of Chinese medicine or some other related drugs, is also not a good thing for the body. So, when it comes to the time when you need to do surgery but do not do it, there is actually a risk, only this risk is not concentrated in a period of time like doing surgery, but a long-term, slowly formed process.
