Patient's question:
Uncle isn't feeling well, so he went to the hospital for a thorough check-up. The doctor said it's avascular necrosis of the femoral head. I'd like to ask how to prevent avascular necrosis of the femoral head from progressing to collapse? What kind of treatment is effective for this condition? What should be done in this situation? Can the pain be reduced? Please reply.Doctor's answer:
Most cases of avascular necrosis of the femoral head begin with pus formation starting from the foot. In the early stages, it can be detected through imaging tests, where the femoral head appears hollow. As the condition progresses, long-term walking puts pressure on the hip joint, causing the femoral articular surface to collapse again. To prevent further progression, you can try femoral head drilling to drain the pus and see if it can fully restore the normal trabecular bone structure. If this doesn't work, you'll need to consider hip joint replacement to alleviate the pain.
