In group – I, the fractures were repaired using intramedullary pinning under glycopyrrolate, fentanyl citrate, triflupromazine hydrochloride and ketamine induction followed by isoflurane maintenance. In group – II, the fractures were repaired using modified intramedullary interlocking nailing under glycopyrrolate, fentanyl citrate, midazolam and ketamine induction followed by isoflurane maintenance. In the present study, both the anaesthetic protocols provided safe and satisfactory anaesthesia in dogs. The incidence of tibial fractures in dogs, in and around Bidar was recorded and of the total 158 fracture cases in dogs, 48 (30.38 %) had tibial fractures. Following fracture repair, the dogs were evaluated for fracture healing on the 15th, 30th and 60th day on the basis of a lameness grade and radiographic evaluation. Progressive improvement in weight bearing was observed from the 0th day to the 60th day. On radiographs, the bridging callus was evident in both groups from the 30th to 60th post-operative day. The biochemical and physiological parameters obtained on the 0th, 15th, 30th and 60th day showed a fluctuating trend and were of very little help in evaluating fracture healing. In conclusion, both techniques are suitable for repair of tibial fractures, however, in group – II, the modified intramedullary interlocking nail was inserted with difficulty and can be further modified to facilitate insertion. The anaesthetic protocol in group – II, showed better results than group – I at the 15th minute after induction.Thesis
