Management of tibial fractures with Orthofix axial external skeletal fixator in 15 dogs

Abstract

In the present study, the applicability of fixator, surgical time, time to weightbearing, the healing time and complications of tibial fractures in dogs after fixation with Orthofix axial external skeletal fixator were evaluated. The study was performed on 15 cases which were presented to the Clinics of Small Animal Surgery. After the determination of the fracture type, fracture location, appropriate screw diameter and the location of the first screw on the fragment according to preoperative radiographs, the dogs were placed under general anaesthesia and the fixator was applied with cranio-medial approach to the tibia. Clinical and radiological examinations were continued until the removal of the external skeletal fixators at three different times (at approx. days 45, 60 and 75) according to the clinical and radiological fracture healing. The treatment results were determined by the Modified Hannover Veterinary Medicine Faculty Small Animal Fracture Evaluation Scale. The results were excellent in eight cases (53.3%), good in four cases (26.7%), fair in one case (6.7%) and poor in two cases (13.3%). Based on this study, the use of external skeletal fixation with Orthofix axial external skeletal fixator can be recommended for dogs with tibial fractures as long as careful pin tract management is performed. Further investigation is needed to determine the use of Orthofix axial external skeletal fixator for the management of other long bone fractures.
