A displaced or comminuted fracture following a fracture of the talus without a cast is OK, and the patient will need surgical treatment. If a patient with a talus fracture has a fracture that is not displaced, treatment without a cast is not acceptable. If the fracture site of the talus fracture is displaced, the patient needs to be cut and repositioned and internally fixed with screws, and at this time the patient can be treated without a cast. In addition, if the talus fracture is a comminuted fracture and the fracture site shows signs of progressive ischemic necrosis, the patient does not need to be treated with a cast, and the patient needs to be treated with tibial talar and subtalar arthroplasty. If the patient’s talus fracture has no fracture displacement, the patient does not cast the fracture site generally can not be healed, the patient needs to be immobilized with a cast until the fracture site is healed. It is recommended that patients with talus fracture need to consult a doctor in time for examination, if the talus fracture is more serious, it needs to be treated surgically, at this time, without casting can be. If the fracture is not serious, the patient needs to be immobilized in a cast.
