Abstract |
There are several factors that can affect the fatigue life of a bone plate, including the mechanical properties of the plate and the complexity of the fracture, position of the screws can influence construct stiffness, plate strain and cyclic fatigue of the plate. No studies have investigated these variables in implants utilized for long bone fracture fixation in dogs and cats. The purpose of the present study was to evaluate the effect of plate working length on construct stiffness, gap motion and resistance to cyclic fatigue of dog femora with a simulated fracture gap stabilized using a 12-hole 2.4 mm LCP. Femora were plated with 12-hole 2.4 mm locking compression plates (LCP) using 2 screws per fracture segment or with 12-hole 2.4 mm LCP using 5 screws per fracture segment resulting in a short working length. |
