Patients who have developed a comminuted ankle fracture can take the following exercises. First, in the early stage of the injury, since the ankle joint is immobilized, the patient needs to continuously and repeatedly flex and extend the toes at this time. In this way, it can effectively accelerate the local inflammation and swelling and promote the healing of the fracture. After a period of recovery, the patient can also practice straight leg raising exercises in bed by tensing the knee joint. Second, after the external fixation device is removed, the patient should perform active flexion and extension of the ankle joint. After that, the patient can also ask the family to help him/her to move the ankle joint passively in order to gradually recover the mobility. Thirdly, after the patient can go down to the ground for weight-bearing activities, it is recommended to first find a weight scale to put the foot on the scale and gradually increase the weight of the affected foot until it reaches full weight-bearing. After this, the patient can practice walking slowly on a flat road, for this time the patient may have insufficient ankle mobility, the patient can take both lower limbs together and stand upright, then slowly squat down and touch the heel with the hip.
