Abstract
A provisional prosthetic system and the surgical methods for utilizing the same. In one embodiment, the provisional prosthetic system includes a keel and a plate configured to be secured to the keel. The keel may further include a body and at least one fin extending outwardly therefrom. The fin functions to prevent rotation of the keel once it is implanted within a bone. In one embodiment, the plate includes a captured screw having a flanged head and external threads. The captured screw is retained by the plate and configured to secure the plate to the keel. In this embodiment, the captured screw extends through an aperture in the plate. Further, the captured screw may be retained by the plate due to the interaction of the flange head and external threads of the captured screw with the top and bottom surfaces of the plate, respectively.
