Abstract:
The current study was undertaken to evaluate the clinical efficacy of Titanium Dynamic Compression plate for repair of femur fractures in dogs. This study was conducted on six dogs presented with fractures to the Department of Veterinary Surgery and Radiology at the College of Veterinary Science, Hyderabad. The six cases of 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 trauma, swelling, non-weight bearing, dangling of the limb and crepitation at the fracture site. Pre-operative radiographic examination in plain orthogonal views, i.e., cranio-caudal and medio-lateral radiographs revealed diaphyseal fractures in all dogs. Pre-operative radiographs also showed the type of fractures as distal transverse fracture of femur in two dogs, mid shaft diaphyseal transverse femur fracture in two dogs, proximal oblique femur fracture in one dog and mid shaft oblique femur fracture in 2 dogs. All fractures are closed, three in right hindlimb and two in left hindlimb and one dog had bilateral femur fracture. These fractures were stabilized with 2.7 mm Titanaium DCP in one dog and 3.5 mm Titanium DCP in five dogs. Good implant stability throughout the treatment period without any complications was achieved all dogs. In all six dogs in the present study showed partial weight bearing on the 1^st post- operative day. All six dogs showed normal weight bearing at rest, the weight bearing of the affected limb while walking from 2^nd Post-operative day in one dog, 3^rd Post-operative day in one dog, 5^th Post-operative day in two dogs, 7^th Post-operative day in one dogs and 8^th Post-operative day in one dog. All six dogs achieved complete weight bearing by 15^th post-operative day. i.e. from Grade V to Grade I. The mean age of the all dogs to bear the complete weight on the affected limb were seen on 5.0±2.28 days. The radiographs obtained on 30^th day Post-operative day revealed proper apposition, decreased fracture gap, appearance of progressive bridging callus with adequate radio-density in all 6 dogs, and on 60^th day revealed continuity of complete cortiomedullary cavity and compete bone formation without any complications with fast healing. Based on present study, it was concluded that Titanium Dynamic compression plating was successful in the treatment of femur fractures in dogs as it is lighter in weight, had superior fatique and corrosive resistance, improved biocompatibility and lower young’s modulus.
