Functional outcome after air-stirrup ankle brace or fiberglass backslab for pediatric low-risk ankle fractures: A randomized observer-blinded controlled trial

Abstract

OBJECTIVES: Pediatric ankle fractures are usually treated by immobilization with either a posterior splint, cast, or ankle brace. We set out to determine if the below-knee fiberglass posterior splint was as effective as the Air-Stirrup ankle brace in returning children with a low risk ankle fracture to their normal level of activity. METHODS: This was a randomized, single-blinded, noninferiority, controlled trial at the Royal Children's Hospital, Melbourne. Children aged 5 to 15 years presenting acutely with a low-risk ankle fracture were randomized to the Air-Stirrup ankle brace or fiberglass posterior splint. A validated self-reported outcome tool, the Activities Scale for Kids performance..
