The external ankle is susceptible to fractures caused by factors such as external trauma or inappropriate sports that sprain the ankle joint. Depending on the extent of the fracture the appropriate treatment can be chosen. Ankle fractures that are not displaced can be fixed with a cast or splint. Displaced fractures need to be repositioned by manipulation followed by external fixation. The fixation period is usually about 3 months. The key to external ankle fracture is the rehabilitation treatment after the fracture. After the fixation treatment, functional exercises should be carried out at an early stage, such as moving the toes at the beginning, and you can do passive massage of the leg muscles, which can effectively improve the blood circulation and promote the swelling, and also prevent the muscle atrophy. When the swelling period is over, you can do some ankle joint activities, which can prevent the sequelae such as adhesions of the ankle joint. After removal of the cast or splint, there may be different degrees of muscle atrophy and joint stiffness, so you can walk with crutches at this time. When you first start walking, there may be pain and the swollen affected limb may swell again. Walking should also be gradual, slowly increasing the amount of activity. You can also shake the ankle joint to increase the flexibility of the ankle joint to facilitate the recovery of the joint function. Improper treatment may leave ankle pain sequelae that may affect future function.
