    The present study was conducted on eighteen clinical cases with long bone distal third diaphyseal fractures in dogs to study the use of two internal fixation techniques namely String of Pearls plating and Positive Profile, End Threaded, Self tapping, Intramedullary pinning including postoperative fracture healing and implant related complications pertaining to these techniques. History, signalment, clinical evaluation, haematological, biochemical and radiographic evaluation and clinical outcome were recorded in all the cases. The animals were randomly divided into 2 groups. In Group I (n=8), the fractures were stabilized by String of Pearls plating and in Group II (n=10), the fractures were stabilized by Positive, Profile, End Threaded, Self-tapping, intramedullary pinning. In group I, the toe and paw touching on the ground was observed as early as 2nd to 5th postoperative day in majority of the dogs and normal limb usage by 10th postoperative day. In group II, the toe and paw touching on the ground was observed as early as 2nd to 5th postoperative day in majority of the dogs and normal limb usage by 15th postoperative day. In group I, there were no implant related complications but dogs 3, 6 and 8 showed non union of fractures where as in Group II, the only implant related complication was of dog 7, which showed proximal migration of implant observed on 90th post operative day radiograph but with satisfactory clinical outcome. In Group I, 90th post operative radiographs of dogs 1, 2, 4, 5 and 7 showed completion of fracture healing with minimal callus at fracture site and with no evidence of fracture line. In Group II, the 90th postoperative day radiographs of all the dogs revealed evidence of bridging callus formation, absence of fracture line, cortical and medullary continuity of the fracture site. Based on weight bearing patterns and radiographic evaluation of fracture healing the clinical outcome was excellent in five cases, satisfactory in one case and poor in two cases of group I and in group II, the clinical outcome was excellent in seven cases, good in one case and satisfactory in two cases. String of Pearls plating has no implant related complications and PPETST intramedullary pinning had less implant related complications with no adverse effects on fracture healing.
