Intramedullary canal diameter reducer

A canal diameter reducer is placed within the intramedullary canal alongside an intramedullary rod to stabilize the intramedullary rod and prevent toggling and/or misalignment due to shear. The canal reducer is an elongated block which may be guided into position by a guide wire and may be held in position during insertion of the rod by a suture extending through hole . The reducer is inserted through an entry opening formed in the end of the fractured bone. The canal reducer may be fabricated from allograft bone or xenograft bone.
