ABSTRACT:
A bone fixation apparatus comprising a shape memory effect material includes a bridge member having at least three sides and an open center portion. Each of the bridge member sides defines a curve having a respective first radius when the shape memory effect material is in a first state, and a respective second radius larger than a corresponding first radius when the shape memory effect material is in a second state. Elongate members are connected to, and extend outwardly from, the bridge member. Each of the elongate members are connected to the bridge member at an approximate intersection of a respective two of the sides, such that each elongate member is subject to a force from each of two intersecting sides, and moves toward the open center portion of the bridge member when the shape memory effect material changes from the second state to the first state.
