Application of the Polyvinylchloride Pipe as a Splint for Comminuted Fracture of the Proximal Phalanx (P1) in a Pony

Abstract

A 9-month old crossbred, 165 kg, male painted pony was presented with severe lameness, pain, and swelling of the proximal phalanx (P1) of the right forelimb. A history taking revealed an accidental slip on the pasture while it was running. Radiographic examination revealed severely
comminuted fracture of the proximal phalanx (P1). External coaptation was performed as fracture stabilization method. The pony was anesthetized and subsequently the 3/4 limb supporting Robert Jones bandage (RBJ) was applied with external support from a polyvinylchloride (PVC) pipe. The inner layer of RBJ was changed forthnightly but the PVC pipe was used until the fracture healed. An optimum fracture healing and a good return to function were achieved within a period of 7 months. However an athletic function may not possible be regained. The advantage of using the PVC pipe is a lower cost of treatment compared to other commercial fiberglass cast. The effectiveness of using the PVC pipe in this report supports the idea of using this material for treatment of severely comminuted P1 fracture in young pony.
