Talus fracture: the upper part of talus is a part of ankle joint, and the blood supply is poor. Ischemic necrosis can occur after injury, leading to disability. Therefore, it is more serious in foot fractures. Most of the fractures are caused by falling from a height and landing on the sole of the foot, and the talus is squeezed between the calcaneus and the lower end of the tibia, causing the talus body to pass through or smash the fracture. If the ankle is dorsiflexive, the anterior tibial margin compresses the talus neck, resulting in a transverse fracture of the neck; On the other hand, if the metatarsus flexes, the posterior margin of tibia compresses the posterior tubercle of talus, resulting in the fracture of the posterior tubercle. Clinical talus neck and body fractures are common. Several ankle fractures of calcaneus can occur at the same time as talus fractures, which are sometimes difficult to distinguish, especially talus body fractures, which need to be diagnosed by X-ray.

Treatment: if the talus neck fracture is not displaced, after the pain and swelling symptoms are eliminated, Jiegu powder and plaster are used externally for 6 weeks. After talus fracture is displaced to the rear, it can be reduced manually, and fixed with plaster after external use of bone powder. Jiegu powder combined with oral medication. The fracture of talus body can be crushed or broken into two pieces, and the upper and lower articular surfaces are often damaged, often accompanied by dislocation. Manual reduction and calcaneal traction are feasible. After external application, Jiegu Powder is fixed with plaster for 8 weeks to avoid load. If the closed treatment fails, peeling during operation should be avoided as much as possible to reduce the possibility of fracture necrosis, and oral Jiegu powder should be taken together with the treatment.
