Cyclic Loading of Periprosthetic Fracture Fixation Constructs

Abstract

Allograft strut-plate constructs are stiffer in bending and have a higher load to failure than a stand-alone locking plate. When an allograft plate construct is chosen, locking screw seemed to provide no mechanical advantage. All three constructs tested retained their mechanical characteristics after 100,000 cycles of loading. Our initial concern that the cables fixing the allograft strut would loosen appears unfounded.
