What reaction does osteonecrosis have

Calcaneal osteonecrosis can cause severe pain and swelling in the ankle joint, making the patient afraid to stand normally, even walking, and easily affecting the range of motion of the ankle joint. If talcaneal osteonecrosis is not treated in time, it may cause local talus collapse, thus causing ankle deformity and abnormal walking posture of the patient; Therefore, when the ankle joint shows obvious pain and swelling, the patient should go to the hospital as soon as possible for X-ray, magnetic resonance and other examinations to determine the situation of talar osteonecrosis. If it is only mild necrosis, it can be treated by physical therapy, drug therapy, etc.; if the degree of talar osteonecrosis is serious, surgery can be performed.
