Bone necrosis is mostly seen in femoral head necrosis, as well as necrosis of the carpal navicular, lunate, talus, etc. It is necessary to accurately determine the degree of bone necrosis as well as the specific location through X-ray examination. Bone necrosis can be sexually active, and there is no obvious effect on bone necrosis. However, after osteonecrosis, we need to find the cause in time and improve the local examination to determine the degree of osteonecrosis. For the early stage of osteonecrosis that is not serious, you can choose drugs that activate blood circulation and remove blood stasis, such as blood circulation and pain relief capsule, danshen tablets and other blood circulation and removal of blood stasis treatment. In addition, try to avoid smoking and drinking. In case of severe osteonecrosis, such as severe necrosis of the femoral head, hip replacement surgery needs to be considered. Osteonecrosis of the talus needs to be considered for surgical treatment such as ankle fusion.
