Pelvic fractures correspond 20 to 30 % of the fractures observed in dogs. They are usually caused by trauma in the posterior region. Complete fractures, especially with bone axis deviation should be surgically treated. The mechanical study of surgical techniques that we can use is very important to evaluate the best way to treat these fractures. The aim of this study was to compare, biomechanically, the use of a dynamic compression plate or screws and polymethylmethacrylate to stabilize a ilial body fracture using a static test. Sixteen canine synthetic pelvis (test specimens) with a transverse osteotomy of the ilial body were used. After the fixation with the implants a load to the acetabulum was applied until fail. The stabilization with polymethylmethacrylate was stronger than dynamic compression plate, resisting to a greater amount of charge in all test specimens
