A biomechanical study of mandibular fracture fixation plates in a bovine rib model

An in vitro study was done using a bovine rib model to evaluate three different plates designed for mandibular fracture fixation. The types of plates tested were the Synthes II, Synthes X, and the Leibinger 3D. The fixated osteotomized rib was loaded up to 150 N at a distance 10 cm from the holding fixture. The superior gap and displacement were measured at 25 N increments for the ribs fixated by each of the plates. The Synthes II plate gave the best fixation having the smallest gap and displacement values.
