About this trial
This is a randomized control trial of pediatric patients with acute lateral ankle avulsion fractures. Patients will be randomized into two groups: Standard of care treatment which includes booting with early range of motion and gradual weening from the boot and a Test treatment which includes a 6 week short-let cast. The purpose of the study is to test whether prolonged immobilization (casting) can help prevent the formation of a subfibular ossicle. The study consists of two patient visits.
