Dogs presented with a history of non-weight bearing lameness were subjected to clinical, orthopaedic and radiographic evaluation for the assessment of fracture healing. Mid-diaphyseal and distal third diaphyseal transversefractures involving radius and ulna and femur were managed with open reduction and immobilisation of fractured bone fragments using 2.7 mm supracutaneous locking compression plate. All dogs were unable to place the foot on the ground (Grade 10) and not able to bear weight on fractured limb (Grade VI) before surgery and gradual improvement in the lameness was noticed on post operative observation. All the dogsreturned to sound gait, normal weight bearing and satisfactory functional limb usage by sixth post operative week except in one dog. Post operative apposition and alignment between fracture fragments was good throughout the observation period.Bone healing with periosteal and endosteal callus formation in three cases (50 per cent)and minimum callus formation in other two cases (33.33 per cent) were observed on postoperative radiographic assessment. Nonunion of fracture was observed in one case(16.66 per cent). The implant was intact and patient acceptance was satisfactorythroughout the observation period owing to its low profile nature. Physiological and haematological parameters were within the normal range. The serum alkaline phosphatase level was high on the day of presentation and significantly decreased (p<0.01) progressively upto implant removal. Implant was removed under sedation in all dogs by six to eight weeks. Based on present study, it was concluded that supracutaneous locking compression plating system was found to be technically feasible and effective in the treatment of long bone fractures in terms of early weight bearing and functional outcomeEnglishThesis
