Osteo-synthesis Use in Dogs’ Femur Surgical Fractures Repair: An Experimental and Comparative Study

Study carried out with the purpose of evaluating the outcomes of dogs’ femur fracture unions by using intramedullary pinning and bone plating fixation. For the study, 8 adult animals, both males, weighing around 8 and 16 kg, were employed. The animals were divided into two similar groups and subjected to a simple complete transverse osteotomy on the left femur. In group 1 (G1), the site of osteotomy was fixed by the intramedullary pinning, in group 2 (G2), an osteosynthesis by plates and screws were placed. The groups were subdivided into 4 periods (P15, P21, P28 and P35) for evaluating x-ray aiming to check local bone union process. X-ray studies showed that G1 developed a faster repair process in all observation periods when compared to G2. This fact was confirmed by radiographic evaluation. We conclude that the intramedullary pinning may be routinely used in orthopedic surgery, providing an early bone healing.
