More than three months after comminuted fracture of the heel bone, walking on the ground with stiffness and weakness of the foot, considering the contracture of the ankle ligament, giving general treatment, physiotherapy, medication, surgery. Three months after the fracture of heel bone, the heel bone has generally healed at this time, walking on the ground with stiffness and weakness, considering the long time of local immobilization, resulting in ankle ligament contracture, accompanied by muscle atrophy of the lower limb. It is suggested that the functional exercise of the ankle joint should be carried out without weight-bearing in the first place with the help of the rehabilitator or family members, including passive ankle joint exercises, including plantarflexion, dorsal extension, internal and external rotation, and generally, after 1~2 weeks, active training can be carried out gradually, with active flexion, extension, internal and external rotation of the ankle, and then, after 1~2 weeks, get out of the bed to practise walking. Physical therapy (short microwave) and oral anti-inflammatory drugs (ibuprofen capsules) can be given during the exercise period. If the stiffness of the ankle joint does not improve after the functional exercise, surgery can be given to loosen the contracted ligaments first, and then carry out the functional exercise of the ankle joint. Walking stiffness and weakness after the healing of heel fracture, it is recommended to actively consult the doctor for treatment under the guidance of the doctor. The use of medication should follow the doctor’s instructions.
