ABSTRACT:
An intrafocal peg includes a body having a first end and a second end. The first end has a greater cross-sectional area than the second end. A blocking member is provided on the peg. The blocking member may take the form of a helical thread or a plurality of unconnected protruding members. The blocking member defines one or two notches. The peg is inserted into the fracture such that the posterior cortical wall of the metaphysis of the radius is located in a notch formed by segments of the blocking member at the first end of the peg. Blocking members may also be provided at the opposite end of the peg to form a second notch in which the anterior cortical wall or the metaphysis of the radius is located.
