The internal methods include bone plates, bone screws, intramedullary pins, circiage wires etc. whereas external fixation devices include K.E. apparatus, Thomas splint, P.O.P. (Gypsona cast splint) other casts and fixation devices. In the cases of mid shaft tibial fracture in the dog, it is not necessary all the times to repair it by internal methods of fixation. External methods of fixation are comparatively cheaper and easy to apply and handle and prevent the animal from the post-operative complications of internal methods of fixation. The present study was launched for the comparison of the external fixation devices used for the repair of mid-shaft tibia fracture in the dog i.e. a) Gypsona cast splint. b) K.E. apparatus. c) Thomas splint. The study was carried out on 12 mongrel dogs of either sex divided into four groups i.e. A, B, C and D and each groups comprising three animals designated as I, II and III. In group A, after the induction of mid shaft tibial fracture Gypsona cast splint was applied on right limb. In group B, K-E. apparatus and in group C Thomas splint was applied. The group D was held sham operated (control) after the induction of mid-shaft tibial fracture. The aforesaid devices were first applied on right tibia and then on left tibia of the same dog at an interval of 10 weeks. The dogs were kept in kennels for 20 weeks. At the end of experimental period, the dogs were euthanized and gross examination was conducted. The results were collected on the basis of clinical examination (lameness) radiographs and post-euthanasia findings. The results clearly revealed that K-E. apparatus was the best choice in cases of mid shaft tibial fracture in the dog, in terms of best immobilization and good calus formation. Although K.E. device is costly one, but it won't exceeds the cost of the animal in many cases. The results were excellent and procedure can easily be applied easily by an average Orthopaedic surgeon. Thomas splint comes next to K-E. apparatus. If properly applied gives good results. Gypsona cast splint was graded at the end, due to its less efficacy and accuracy. It usually resulted in bone bending after application. It could have been a better procedure if applied with some metallic cast or splint. ER -
