Abstract:
The present clinical study was conducted on seven dogs presented with tibial fractures to Department of Surgery and Radiology at CVSc., Rajendranagar, Hyderabad. The age ranged from 9-42 months, six were male and one was female. The body weight ranged from 12 to 40 kg. Pre-operative radiographs showed as transverse in 3 dogs, oblique in 2 dogs, comminuted in one dog and spiral in one dog. These fractures were stabilized with 5.0 mm, 6.0 mm, 7.0 mm and 8.0 mm interlocking nails. Cranio-medial parapatellar approach provided good exposure of the fracture site. Follow-up radiographs on 15^th, 30^th, 60^th and 90^th post-operative days revealed secondary bone healing with periosteal callus formation. Good implant stability without any complications in six dogs. In one dog, nail bending was observed above the fracture site by 15^th post-operative day due to overuse of stabilized fractured limb and heavyweight of the dog. All the dogs showed grade V lameness before surgical treatment. Post-operatively, four dogs progressed to grade I lameness by 30^th day, two dogs progressed to grade I lameness by 60^th day and one dogs progressed to grade II lameness by the end of 60^th day. It was concluded that IILN was successful in the treatment of tibial fractures in six out of seven dogs. The application of interlocking nail was found to be effective with features like being light in weight and provides resistance against axial, torsional and bending forces. And opined that IILN has potential for application for repair of tibial fracture in dogs.
