Can osteonecrosis of the femoral head be completely cured? Is it better to be more active or less active with osteonecrosis of the femur? How can I cure ischemic osteonecrosis of the femur? How long does it take to walk? Can it be cured without surgery? Ischemic necrosis of the femoral head is a difficult disease to cure, and many orthopedic surgeons at home and abroad are trying to find ways to treat it, but so far, there is no 100% effective treatment. Conservative treatment by just taking drugs is the least effective and can only relieve the symptoms, with little possibility of recovery. Various head-preserving surgeries have some efficacy before the femoral head collapses, and some patients (40%-50%) are able to recover because of the surgery and do not need to have other surgeries, but there are still some patients who cannot recover completely. For patients with early ischemic necrosis of the femoral head (stage 2 or less), we use decompression implant support surgery (allograft fibula or metal tantalum rod grafting), which can cure some patients with early osteonecrosis. Please bring your clinical information to my clinic to advise you on whether you are a candidate for early head preservation surgery.
