Abstract

A surgical bone reamer includes a rotatable, elongated shank having a proximal end, a distal end and a longitudinal axis, and a reaming head mounted on the distal end. A plurality of equally spaced walls are radially disposed on the reaming head around the longitudinal axis, and tip edges for penetrating bone are defined on the radial walls to be disposed angularly with the longitudinal axis. Reaming edges joined to the tip edges extend longitudinally from the tip edges in the proximal direction parallel to and an equal radial distance from the longitudinal axis for reaming a cylindrical tunnel when the reaming head is rotated in bone. Tapered flutes disposed angularly between the tip edges and the radial walls permit bone to be evacuated through the reaming head when forming a tunnel in bone.
