A screw fixation system serves to facilitate attachment of an orthopedic implant to a fractured bone to facilitate healing thereof. The screw fixation system includes the orthopedic implant, a bone screw, and a screw fixing element. The orthopedic implant includes an opening formed thereby. The screw fixing element has a body including an aperture extending between upper and lower surfaces thereof, and a channel adapted to receive a portion of the orthopedic implant adjacent the opening. When the portion of the orthopedic implant is received in the channel and the bone screw is inserted into the aperture, engagement of at least a portion of threads formed on a head of the bone screw and threads formed in the aperture expands the screw fixing element against the orthopedic implant to fix the bone screw and the orthopedic implant relative to one another. |
