Epoxy-pin external skeletal fixation for treatment of open fractures or dislocations in 36 dogs

The objective of the study was to report an epoxy-pin external skeletal fixation system for treatment of open fractures/dislocations, and outcome in 36 dogs. Epoxy-pin fixators were used to repair open fractures (n=30)/dislocations (n=6) distal to the stifle/elbow joints, using 1.2–2.0 mm K-wires fixed at different levels. Fixation wires in the same plane were bent and joined; and using additional wires scaffolds for connecting bars/rings were constructed. Thoroughly mixed epoxy putty was applied over the scaffold to create permanent connecting bars and rings. Dogs were evaluated clinically and radiographically at regular intervals until healing. Results showed that epoxy-pin fixation provided stable fixation with early weight bearing. Open wounds generally healed within 10 days and full weight bearing observed within 3 weeks in most of the dogs. With two exceptions, there was no appreciable damage or deformation of fixator components, and fixation maintained until healing occurred. The technique was easy, inexpensive, lightweight, and versatile to provide stable fixation of open fractures and dislocations below the stifle and elbow in dogs.
