In this clinical study, it is aimed to determine the usability of minimal invasive plate osteosynthesis of tibial shaft fractures in dogs by using and evaluating the obtained radiological and clinical results. The study group consisted of 8 dogs of dif-ferent breed, age and sex with hind limb lameness caused by motor vehicle accidents. They were admitted to the Department of Ort-hopaedics and Traumatology Clinic, Faculty of Veterinary Medicine, Ankara University between 1999 and 2001. According to the clinical and radiological examination tibial fractures were detected and 3.5 mm dynamic compression plate (DCP) with 6, 8, and 10 screw holes were preferred for fracture fixation. Surgical approach was maintained to the medial aspect of the tibia with two lon-gitudinal incisions approximately 3 cm in length, proximal and distal of the fracture line. A blunt point elevator was applied lon-gitudinal to the cortical surface through any incision along the fracture line, in such a manner that it was visible through the other in-cision. The plate is then pushed along in the layer between the muscle and periosteum adjacent to the surface of the bone. After fracture reduction, 2-3 cortical screws (d=3,5 mm) were applied on the screws' holes seen through the incision line at the end of the plate so that screw insertion is restricted to the proximal and distal fragments. Incisions were closed routinely. Fixation and reduction were evaluated post operatively by radiographie examination. After the operation the animals were periodically controlled by means of radiological and clinical examination. Although partially loss of the limb alignment has been found in some cases, these fractures healed successfully and improved fast. The minimally invasive plate fixation had shorter operative times than conventional plate fi-xations. This method has also been seen applicable even in cases of unfragmented diaphyseal fractures. The plates were removed 9-10 weeks after operation and no complication has been observed postoperatively.
