A l-year-old male Collie was admitted to the Stange Memorial Clinic Oct. 3, 1948. He had been injured the previous week in a dump-box accident which resulted in a compound comminuted fracture of the right tibia and fibula approximately 1112 inches proximal to the hock joint. The local veterinarian, who first attended the case, had applied a conventional wood splint to the leg but later referred the case to the veterinary hospital with an unfavorable prognosis.
