Surgical plates are now being customized thanks to DePuy Synthes CMF (Craniomaxillofacial). The company, which provides skeletal and soft tissue repair and reconstruction, is part of DePuy Synthes Companies of Johnson and Johnson. Its new Patient Specific Plates for Mandible (PSPM) are customized according to patient anatomy and surgeon specifications. DePuy Synthes CMF PSPM was recently added to the company’s TRUEMATCH CMF, which offers preoperative planning services, intraoperative tools, and patient-specific devices to assist surgeons with accuracy.
Matthew J. Bak, MD, was one of the first surgeons in the country to operate with the TRUEMATCH CMF PSPM. He commented that it allows for a more individualized reconstruction with more control of plate design and screw placement. The PSPM has customizable design features surgeons can select, including plate thickness and shape, and screw hole locations, pattern, and angulation. After that, DePuy Synthes CMF engineers design and create the plate to the patient anatomy. The plate, 3D milled from solid titanium, is never bent—eliminating plate bending in the operating room, which can cause mechanical stress and increase the possibility of plate breakage.
The PSPM is developed for use with PROPLAN CMF surgical guides, which have integrated drill sites to create the bone holes that align with the plate holes to aid transfer of the surgical plan to the operating room. Anatomic bone models are made from original patient CT scans or to the planned outcome. The PSPM is available in 2.0 mm and 2.5 mm thick profiles. Both have greater fatigue life over the 2.5 mm MatrixMANDIBLE flat plats, while the 2.0 mm thick plate also has great strength with lower profile.
