The sequelae of heel fracture mainly include: 1. tibial nerve injury. After the fracture of the heel bone, the fracture block compresses the tibial nerve passing through the medial ankle canal, resulting in local numbness, pain, and weakness with calf cramps. 2. Skin necrosis. As the surface of the heel bone is both skin, a large amount of bleeding after the fracture leads to increased skin tension and ischemic necrosis when the blood supply becomes poor. 3. Pneumonic pneumonia. The fracture requires bed rest during the recovery process, and bed rest is prone to complications of pulmonary inflammation. 4. pressure sores. The fracture of the lower extremity is prone to deep vein thrombosis. 6. Especially after surgery or open fracture, due to more exudation and longer time, easy to cause infection. 7, traumatic arthritis. Damage to the articular surface of the heel bone can easily lead to traumatic arthritis. 8. Stiffness of the ankle joint. After the fracture, it needs to be fixed for a long time, which may lead to stiffness due to adhesion of the surrounding tissues.
