The fractures were diagnosed by clinical signs, orthopaedic examination and survey radiography. Pre-operative radiographic examination in two plain orthogonal views, i.e., cranio-caudal and medio-lateral radiographs revealed closed mid diaphyseal transverse fractures of radius and ulna.

These fractures were stabilized with 2.7 mm PC-Fix in one dog and 3.5 mm PC-Fix in three dogs and resulted in good fracture fixation and immobilization. In dogs weighing less than 10 kg, 2.7mm Point Contact Fixator (PC-Fix) plates were used and in dogs weighing more than 10kg, 3.5mm Point Contact Fixator (PC-Fix) plates were used. The length of the plates and screws to be used was determined by the length of the bone and trascortical diameteras measured from the mediolateral and cranio-caudal radiographs obtained pre-operatively.

Immediate post-operative radiographic evaluation confirmed proper placement of the plates and screws, apposition and alignment of the fracture fragments in all the eight dogs. Immobilization was considered satisfactory in all the cases. The plate length, size and position were appropriate in all the cases. Screw length, size and position were found to be appropriate in all the cases. Follow-up radiographs taken on 15^th, 30^th, 45^th and 60^th post-operative days revealed primary bone healing with minimal callus formation. Good implant stability throughout the treatment period without any complications was achieved in all dogs. All the dogs which were diagnosed showed grade V lameness before surgical treatment. Post-operatively, all dogs progressed to grade I lameness by the end of 30^th post-operative Based on the present study, it was concluded that Point Contact Fixator plating was successful in treatment of radius ulna fractures in dogs and offered good recompense and remarkable improvement in limb function with good fracture stability till the completion of the bone healing.
