Recovery exercises for patients with comminuted heel bone fractures are performed in three main phases, i.e., the cast immobilization phase, the fracture healing phase, and the late rehabilitation phase. The content of recovery exercise is different in each stage. 1. Cast immobilization period: usually patients with comminuted heel fracture will be immobilized with a cast for about one and a half months, during this period, because the ankle joint can not move normally, you can rest in bed, elevate the affected limb, and carry out toe dorsiflexion and extension activities, as well as straight-leg elevation activities. Exercise toe flexion and extension and leg muscle strength, and promote the swelling and bruising of the heel area to subside. 2. Fracture healing period: the fracture will gradually heal in about one and a half months after the heel fracture, at this time, you can remove the cast and take the initiative to perform ankle joint exercises in all directions to promote blood circulation and prevent muscle atrophy. 3. Later stage of rehabilitation: three months after the fracture, you can carry out appropriate weight-bearing training, gradually increase the amount of activity, and exercise the heel, so that the patient gradually regain the function of walking. Patients should pay attention to gradual recovery exercise, not strenuous exercise, in order to avoid re-injury. Physical therapy such as hot compresses and massage can be used to relieve symptoms and promote recovery. It is recommended that patients under the guidance of a professional physician or rehabilitation therapist to carry out recovery exercises.
