Unilateral uniplanar external skeletal fixation for isolated diaphyseal tibial fractures in skeletally immature dogs.

Abstract

OBJECTIVE: To report and evaluate use of external skeletal fixation (ESF) for repair of isolated (fibula intact) diaphyseal tibia fractures in skeletally immature dogs. STUDY DESIGN: Case series. ANIMALS: Skeletally immature (mean age, 17 weeks; range, 12-23 weeks) dogs (n=5) with isolated diaphyseal tibial fractures. METHODS: Medical records (2006-2007) of 5 dogs with isolated diaphyseal tibial fractures treated with Type 1a ESF were reviewed and outcome assessed by clinical examination and telephone interviews. RESULTS: Dogs were evaluated approximately 2 and 4 weeks after surgery. Limb function, muscle mass, and comfort level remained very good to excellent throughout healing. Bony union was confirmed radiographically and the ESF removed approximately 4 weeks after surgery (mean, 31.4 days; range, 28-37 days). Owner satisfaction was high when contacted a minimum of 4 weeks after ESF removal. CONCLUSIONS: Use of Type Ia ESF with positive profile threaded pins is a practical and biologic method for treatment of isolated tibial fractures in skeletally immature dogs CLINICAL RELEVANCE: ESF is an effective alternative treatment to external coaptation and internal fixation for isolated diaphyseal tibial fractures in skeletally immature dogs.
