Use of a new investigational interlocking nail supplement in the repair of comminuted diaphyseal tibia fractures in two dogs.

Abstract

Two dogs were diagnosed with highly comminuted diaphyseal tibial fractures following traumatic incidents. Investigational hybrid interlocking nail (ILN) bolt/external skeletal fixator (ESF) pins were used to repair both fractures. The surgery was successful, and fractures healed without complications by 6 weeks (case no. 1) and 17 weeks (case no. 2) after surgery. This article describes the application and the advantages of a new, investigational ILN supplement that was specifically designed to accomplish initial rigid stability and allow progressive destabilization to the fracture repair. The authors are continuing to study the biomechanical properties of this procedure in order to accurately establish clear recommendations for its use in certain fracture situations.
