Bioabsorbable interference bone fixation screw

摘要

An interference bone fixation screw fabricated from bioabsorbable material includes a body having a proximal end, a distal end and a screw thread disposed therealong from the proximal end to the distal end. A drive recess is formed in the body to extend longitudinally from the proximal end toward the distal end for receiving a rotatable driver. The drive recess defines a plurality of radial force receiving surfaces for receiving concentric forces from the driver applied perpendicularly to the force receiving surfaces.
