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

Abstract

To report and evaluate use of external skeletal fixation (ESF) for repair of isolated (fibula intact) diaphyseal tibia fractures in skeletally immature dogs. Case series. Skeletally immature (mean age, 17 weeks; range, 12-23 weeks) dogs (n=5) with isolated diaphyseal tibial fractures. 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. 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. 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 ESF is an effective alternative treatment to external coaptation and internal fixation for isolated diaphyseal tibial fractures in skeletally immature dogs.
