Bracing versus casting in ankle fractures

Abstract

Casting and splinting techniques for treating patients with fractures have been used for centuries. Functional bracing after ankle fracture has recently been utilized in an effort to avoid the atrophy and stiffness sometimes associated with casting; functional bracing allows for early mobilization of the ankle joint during recovery. Our review investigated the published literature comparing bracing with casting after ankle fracture. Studies examining both operatively and nonoperatively treated ankle fractures were included. There is minimal evidence supporting the use of functional bracing over cast immobilization to improve functional outcome, range of motion, swelling, or post-traumatic arthrosis after ankle fracture in the long term. The primary benefits of functional bracing are the potential to return to work earlier and bracing may facilitate activities of daily living, such as bathing and dressing. In addition, there may be a decreased patient risk of developing deep vein thrombosis due to immobilization. However, there is an increased risk of wound infection when using a brace after open reduction and internal fixation of an unstable ankle fracture. Functional bracing can be used for treating stable and postoperative ankle fractures in compliant patients to potentially expedite and facilitate the recovery process.
