Abstract
A bone rifling system for use in prosthesis, which allows improved prosthetic bone fixation. The system comprises orthopedic undercut reamer, which can cut controlled internal groove circles or spiral grooves on the internal surface of host bone. The system converts the commonly reamed smooth bone to grooved or rifled bony tube. Used together with bone cements, the bone rifling system ensures prosthetic bone fixation by significantly increasing the pull out strength, and decreasing the rate of clinical loosening and failure of replacement joints. Also disclosed is a method for preparing a bone for a prosthesis using such a bone rifling system to cut grooves in a host bone for increased prosthetic bone fixation.
