Six dogs suffering from long bone fractures were immobilized under general anesthesia by using commercially available fiber glass cast. Automobile accident was recorded as cause for long bone fracture in 5 dogs ( %) while fall from height was recorded in 1 ( %) dogs. 3 cases (50 %) were diagnosed as simple oblique fractures and 3 cases (50 %) as simple transverse fractures. Propofol provided adequate depth of anaesthesia and smooth recovery in young dogs less than 6 months of age. Immobilization with of fiberglass cast was easy and less time consuming. Method of application was simple and less cumbersome. Fiberglass cast attained its toughness . in around 5-8 minutes. Fiberglass cast was found radiolucent, lighter in weight, stronger and durable compared to a conventional plaster of paris. Few of the complications such as muscular atrophy, excoriation on skin and swelling were noted during the study. | Efficacy of fiber glass cast in treatment of long bone fractures in clinical cases of dogs
