Minimally invasive orthopedic surgery using a milling machine presents challenges. The milling machine we developed has a redundant axis to minimize cutting-tool contact with surrounding soft tissue. Important components are modeled based on physical requirements, and model-based geometric optimization improves performance. Here we discuss the protective mechanism, hardware, and software we developed to cover the nonworking cutting-edge portion and to protect against soft-tissue damage. We evaluated the effectiveness of this approach using cadaveric bone.
