| Abstract Scope |
The standard procedure to prepare fixation plates for patients who have suffered severe trauma is to manually and iteratively bend them to fit the patient's anatomy in the operating room. That design process does not include biomechanical simulation of the fixation plate once it is in place. The surgeon's decisions on fixation plate size, shape, material, and location are based on their experience. We report here on a closed-loop fabrication process that presents personalized, optimal plate design based on simulation of its post-operative biomechanical performance using proprietary Virtual Surgical Planning (VSP) tools created in the 3D Slicer environment. We obtain the bending angles from the final VSP fixation plate shape and transfer it to a robotic plate bender. Scanning tools are employed to ensure that the bent plate matches the original design. These suites of tools were created at the NSF-funded Point-of-Care Manufacturing Testbed at the HAMMER Engineering Research Center. |
