Talar necrosis

Talus necrosis and ischemic necrosis are more common. The talus is the only bone in the whole body without muscle attachment and stoppage. When the ankle joint is severely damaged, the blood supply to the talus can be completely destroyed and ischemic necrosis occurs. Ultimately, the talar body collapses and deforms, causing ankle osteoarthritis. Therefore, the prevention and early treatment of talar ischemic necrosis plays an important role in its function. Talus fractures are the main cause of talar necrosis, and only about 10% cause talar necrosis. Talus necrosis should be actively treated according to the cause, and glucocorticoids are prohibited (which can cause osteonecrosis). After talar necrosis, talar fracture, dislocation, the treatment was not timely. The incidence of ischemic talar necrosis was 50% to 80%. Kenwright (1970) reported 58 cases of talar injuries, 2 lateral talar body fractures and dislocations, and all were avascular talar necrosis .
