Abstract:
1. A system for repairing acetabulum fractures, the system comprising: a bone plate configured to be fixed into a non-planar portion of the pelvis in a direction from the bone to the bone plate, such bone plate comprising an elongated body in a longitudinal direction, the elongated body having an upper face, a lower face opposite of the upper face; and opposing side faces that extend between the upper face and the lower face, such opposite side faces comprising a plurality of opposing pairs of notches configured to allow lateral flexion of the bone plate; a plurality of openings aligned along a longitudinal axis of the bone plate and which extend through the upper face and the lower face of the elongated body, each of the plurality of openings being at least partially defined by a sidewall that extends from the upper face to the lower face of the body each sidewall having a surface that is substantially planar and is angled inwardly in a direction from the upper face toward the lower face of the body of the bone plate to prevent rotation of the sex bolt head within the opening; and a sex bolt without external thread comprising a hollow shaft sized to pass through any of said plurality of openings of the elongated body of the bone plate, the hollow shaft defining an opening at a distal end thereof and comprising internal threads that are configured to cooperatively couple with external threads of a screw, the hollow shaft further defining a longitudinal axis; and a head sized to cooperate with the sidewall of any of said plurality of openings to prevent the sex bolt from passing completely through an opening of any of said plurality of openings when the hollow shaft of the sex bolt is advanced through the opening in a distal direction and into a pelvis through an interior surface of the pelvis, and such that the head of the sex bolt is configured to permit translation relative to the sidewall when the head of the bolt is within the sidewall to allow three dimensional fracture fragment reduction, the head comprising a surface that is configured to cooperate with the sidewall to prevent the sex bolt from rotating about the longitudinal axis as a screw is advanced through the opening at the distal end of the sex bolt and is coupled with the internal threads of the sex bolt.
