Ankle immobilization support is an external immobilization device that can play a role in supporting and protecting and promoting rehabilitation in the treatment process after tendon injury, ankle fracture and sprain. The ankle joint support has a very strong immobilization and protection effect, the main role is to fix in a certain desired position in ankle injuries, it can be used for both ordinary ankle sprains and serious ligament and tendon ruptures and ankle fractures. It is important to use it for the duration of the immobilization; patients with early ankle injuries may need to be immobilized throughout the day. If the patient has a simple soft tissue injury, the brace can be used for external immobilization only during the day and can be removed at night when resting. For patients with less severe ankle fractures that do not require external immobilization with casts and whose fracture breaks are not dangerous, the ankle joint can be fully immobilized with a brace, which immobilizes and protects the ankle joint and prevents excessive ankle joint movement, which in turn triggers tendon and muscle pulling that leads to fracture dislocation. Patients with more serious symptoms should wear the brace all day long in the early stage, and should not take it off because of the inconvenience. After 2~3 weeks, the fixation time can be set in the daytime, and the brace can be taken off at night when they are resting. At the same time, when the injury site is repaired and healed to the point where simple exercises can be performed, joint function recovery exercises should be carried out as early as possible to gradually increase weight bearing and better stimulate tissue regeneration. After the fracture is fully recovered, the patient can remove the brace and gradually increase the amount of exercise to promote muscle exercise and joint rehabilitation in the later stages of recovery. Warm reminder: If you feel uncomfortable while wearing the brace, you should go to the hospital in time for examination.
