Functional Walker Boots are Preferred to Synthetic Casts by Patients and Carers in the Management of Pediatric Stable Ankle Injuries.

INTRODUCTION

Traditionally children who presented with a stable ankle injury have been managed in a below-knee synthetic cast. No previous study has investigated patient and parents/carer preference between synthetic casts and walker boots.

METHODS

Children aged between 6 and 16 years who presented with stable ankle injuries (ankle sprains, small fragment avulsions, and fibular Salter-Harris 1 injuries) were randomized to receive treatment with either a synthetic cast or a walker boot. A tailored, study-specific questionnaire was designed and completed at 4 weeks from injury to evaluate both patient and parents/carer preference. An analysis of costs associated with both treatments was performed.

RESULTS

Ninety-one patients were available for final analysis. Forty-seven received synthetic cast treatment and 44 walker boot treatment. Patient demographics and injury types were matched between groups.Statistical significance was found in favor of the walker boot with regard to comfort, reduction in activity during treatment, and patient-reported problems at the end of treatment. There was a strong and significant preference toward treatment with the walker boot, both from patients and parents/carers. There was no difference between groups with regard to walking ability, analgesia requirement, and patient-reported pain scores.Unplanned attendances to the hospital during the treatment period were higher in the synthetic cast group. The overall treatment cost per patient was lower with the walker boot.

CONCLUSIONS

In children who present with stable ankle injuries, treatment in a walker boot is preferred by both patients and parents/carers. It results in fewer unplanned attendances to the hospital, is less expensive, and we recommend it as the treatment of choice in stable pediatric ankle injuries.
