Prevention of the Os Fibulare After an Acute Lateral Ankle Avulsion Fracture in Pediatric Patients: A Randomized Control Trial
Texas Scottish Rite Hospital for Children
Summary
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.
Description
This is a randomized control trial for pediatric patients who present to Scottish Rite for an acute lateral ankle avulsion fracture. Patients will be randomized into standard of care treatment or prolonged immobilization (test treatment). Standard of care treatment is booting with early range of motion or test treatment and gradually weaning from the boot. Test treatment (prolonged immobilization) is 6 weeks of immobilization in the form of a short-leg cast. The purpose is to see if prolonged immobilization will promote healing of the avulsion fracture and prevent the formation of a subfibular…

Interventions
- ProcedureProlonged Immobilization (Casting)
Patients will be treated with a non-weightbearing short-leg cast for 6 weeks to promote avulsion fracture healing. This will be followed physical therapy, and a gradual return to activity.
- ProcedureStandard of Care (SOC)
Patients will receive brief immobilization (boot) as needed, followed by early range of motion exercises. Physical therapy and a return-to-activity plan will be implemented as symptoms allow.
