Abstract: The present clinical study was conducted on six young dogs presented with radius-ulna fractures to Department of Surgery and Radiology at College of Veterinary Science Rajendranagar, Hyderabad. The age of the six dogs ranged from 4 - 13 months. Out of these six dogs, four were males and two were females. Among the six dogs, two dogs belonged to spitz breed and four dogs belonged to non-descript breed. The body weight of the dogs ranged from 5 to 13 kg. The six cases of radius-ulna fractures were diagnosed by clinical signs, orthopaedic examination and survey radiography. The symptoms observed in the dogs presented for treatment were pain on manipulation, abnormal angulation, and lameness immediately after traumatic injury, swelling, non-weight bearing, dangling of the limb and crepitation at the fracture site. Preoperative radiographic examination in two orthogonal views, i.e., anteroposterior and mediolateral radiographs revealed distal diaphyseal fracture in three xvi dogs, mid-diaphyseal fractures in three dogs. Preoperative radiographs also showed the type of radius-ulna fractures as transverse fractures in two dogs, short oblique fractures in two dogs, long oblique fracture in one dog and comminuted fracture in one dog. All the six dogs had closed fractures. These fractures stabilized with 2.0 mm VCP in one dog, 2.7 mm VCP in four dogs and two 2.0 mm stacked VCP in one dog resulted in good fracture fixation and immobilization. The length of the plates to be used was determined by the length of the bone as measured from the radiographs. The lengths of screws were determined by measuring the transcortical diameter of the bone at different regions from the mediolateral radiographs obtained preoperatively. Craniomedial approach used provided good exposure of the fracture site and enabled good fracture fixation. Postoperative radiographic evaluation confirmed proper placement of the plates and screws, apposition and alignment of the fracture fragments in all the six dogs. Immobilization was considered satisfactory in all the cases. The plate length, size and position were appropriate in all cases. Screw length, size and position were considered appropriate in all cases. Follow-up radiographs taken on 7th, 15th, 30th, 45th and 70th postoperative days revealed primary bone healing with minimal callus formation. Good implant stability throughout the treatment period without any complication was achieved in five dogs. In one dog two distal screws loosening due to jumping from height and synostosis between radius and ulna was observed by 30th postoperative day. However, there was no loss of stability in the fractured limb. Mild valgus deformity was observed in this dog. All the dogs which were diagnosed for radius-ulna fractures showed grade V lameness before surgical treatment. Postoperatively, all the six dogs progressed to grade I lameness by the end 45th postoperative day. xvii Haematological evaluation revealed that the progressive increase of haemoglobin level, packed cell volume and total erythrocyte count on postoperative days indicated erythropoiesis. The total leukocyte count was significantly decreased on postoperative days indicated leucocytopenia which is suggestive of gradual decrease in inflammatory reaction. The differential leucocyte count like neutrophil was significantly decreased on postoperative days indicated neutropaenia. Contrary to this, the lymphocyte count was statistically increased on 14th and 45th postoperative days indicated gradual decrease of inflammatory reaction. Serum biochemical evaluation revealed that the serum alkaline phosphatase and serum calcium values significantly increased from day 0 to 14th day and thereafter reached to normal values by 45th postoperative day. The increased serum alkaline phosphatase levels during the first two weeks indicated increased chondroblastic proliferation to cause bone formation during fracture repair. The serum phosphorous values showed no significant variation and the values were within the normal range. Based on present study, it was concluded that Veterinary Cuttable Plates (VCP) was successful in the treatment of radius-ulna fractures in puppies and small breed dogs and offered good recompense and remarkable improvement in limb function with good fracture stability till the completion of the bone healing in all the dogs. The implant used in this technique was economical, making it amenable to use in veterinary practice. As there is increasing demand for fracture treatment in young and small breed dogs, these VCPs being compliant construct with their add on features over the other bone plates can be used with excellent clinical outcome for the treatment of radial fractures in young and small breed dogs.
