Osteossíntese com placa e pino em cães e gatos / Plate-rod osteosynthesis in dogs and cats

ABSTRACT

Background: Most fractures are caused by traumatic processes due to car accidents, but they can also occur due to bullets,fights and falls. Surgical stabilization is often necessary and shows high rates of bone healing when its basic concepts arefollowed. The objective of this study is to report cases of shaft fracture in long bones stabilized with intramedullary pinand plate (IMPP) in order to evaluate pre- and postoperative clinical and radiographic signs, correlating the ideal surgicaltechnique described on recent studies with complications resulting from the surgical procedure.Cases This study includes patients undergoing osteosynthesis with intramedullary pin and plate from January 2015 toDecember 2016 at the Veterinary Medical Teaching Hospital of UFRGS. During this period, 13 animals (five cats andeight dogs) with long bone fractures were treated with the abovementioned association. Information on breed, age, sex,etiology of the fracture, affected bone, clinical signs, osteosynthesis technique, clinical progress, fracture healing, andpostoperative complications was collected for the study. Late postoperative recovery was evaluated by telephone contactwith owners. The mean age was 5.4 years (3 months - 15 years) and body weight 17.66 kg (3 - 28.4 kg). The fractureswere due to being hit by a vehicle (5), bites (1), accident with a toy (1), and unknown (6).Discussion: All cases included in this study were in the femur, humerus or tibia. Fractures in the radius are also frequent insmall animal traumatology, but in this case the use of an intramedullary pin is not recommended. All animals had diaphysealfractures, which is an important prerequisite for IMPP stabilization. The IMPP association is mainly indicated in casesof comminuted fractures, when it is anatomically impossible to reduce fracture fragments, as occurred with nine patientsin this study. The plate did not break of fail in any of the cases, as the association...
