How long the femoral head can last after decompression surgery is not fixed, some can be several years, some do not have obvious effect, there are individual differences, specifically related to the extent of the disease, postoperative recovery, care and so on.
Femoral head decompression surgery is a common method to treat femoral head necrosis, which is mainly used for patients with early and middle stage femoral head necrosis. After drilling and decompression treatment, some patients can alleviate their clinical symptoms and maintain for several years or even longer, but some of the patients do not have obvious effect.
Some patients with femoral head necrosis undergoing decompression, still frequently performing weight-bearing activities after the operation, and the presence of severe smoking and drinking, the maintenance time will be shorter, and the reoccurrence of femoral head necrosis will occur soon after the operation.
It is recommended that after decompression surgery, patients should avoid weight-bearing activities, develop good living habits, try to quit smoking and drinking, and have a timely review if there is any discomfort.
