Department of Veterans Affairs, 500 Foothill Drive (151), Salt Lake City, UT, United States; Department of Orthopaedics, University of Utah, 590 Wakara Way, Suite A100, Salt Lake City, Utah, United States; Department of Biomedical Engineering, University of Utah, 36 S Wasatch Drive SMBB 3100, Salt Lake City, Utah, United State. Electronic address:

Percutaneous osseointegrated (OI) devices have an endoprosthesis attached to the residual bone of an amputated limb, then pass permanently through the skin to be connected to the distal prosthetic componentry outside of the body. Whether the bone-anchoring region of current OI endoprostheses are cylindrical, and/or conical, they require intimate bone-endoprosthesis contact to promote stabilizing bone attachment. However, removing too much cortical bone to achieve more contact leads to thinner and, subsequently, weaker cortical walls. Read More
