Unilateral Uniplanar External Skeletal Fixation for Isolated Diaphyseal Tibial Fractures in Skeletally Immature Dogs

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 ～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 ～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.
