New Mandible Plate “Seamlessly Integrates Surgical Planning, Intraoperative Tools and Patient Specific Devices

DePuy Synthes CMF (Craniomaxillofacial), has announced the launch of Patient Specific Plates for Mandible (PSPM), new plates that are customized based on surgeon specifications and individual patient anatomy.

Background

Earlier this week we covered the tale of French company Medicrea’s customizable, patient specific spinal rods. The concept of pre-planning surgery to include delivery of implants that are optimised for the individual patient is one that is also embraced by DePuy Synthes CMF’s new mandible plates.

DePuy Synthes CMF, a division of DePuy Orthopaedics, Inc., is a leader in skeletal and soft tissue repair and reconstruction and part of the DePuy Synthes Companies of Johnson & Johnson. The PSPM is the company’s latest addition to its TRUMATCH® CMF, a portfolio of preoperative planning services, intraoperative tools and patient-specific devices designed to help surgeons achieve their goals of accuracy, efficiency and patient care.

The DePuy Synthes CMF PSPM includes a range of customizable design features that the surgeon can select before surgery including plate thickness and shape, and screw hole locations, pattern and angulation. DePuy Synthes CMF engineers then design and manufacture the plate to the pre-planned patient anatomy. The plate is 3D milled from a solid block of titanium to its final shape and is never bent. This eliminates the need for plate bending in the operating room, which can induce mechanical stress and increase the potential for plate breakage.

In addition, the DePuy Synthes CMF Patient Specific Plate for Mandible is optimized for use with PROPLAN CMF®* surgical guides. These guides have integrated drill guides for creating the bone holes, which are designed to align with the plate holes to facilitate transfer of the surgical plan to the operating room. Anatomic bone models may be created from original patient CT scans or to the planned outcome, to provide tactile and visual representation of the surgery to enhance patient understanding.

The DePuy Synthes CMF Patient Specific Plate for Mandible is available in 2.0 mm and 2.5 mm thick profiles. Both these profiles have improved fatigue life over the company’s 2.5 mm MatrixMANDIBLE™ flat plates, and the 2.0 mm thick plates offer greater strength with lower profile, as compared to the 2.5 mm MaxtrixMANDIBLE flat plates.

Physician comments

“PSPM gives the reconstructive surgeon greater control over plate design and screw placement which assists in planning of future dental restoration, ultimately leading to a more individualized reconstruction,” said Matthew J Bak, MD, an ENT-otolaryngologist and assistant professor at Eastern Virginia Medical School, Norfolk, VA, who was one of the first surgeons in the country to do an operation with the TRUMATCH® CMF PSPM.

Company comments 

“TRUMATCH CMF Solutions portfolio provides advanced technology and procedural support for facial reconstruction, orthognathic surgery, distraction, and cranial reconstruction,” said Mike Mazzio, Worldwide President, DePuy Synthes CMF. “With DePuy Synthes CMF Patient Specific Plate for Mandible, we are able to offer a total reconstruction solution that seamlessly integrates surgical planning, intraoperative tools and patient specific devices to help surgeons achieve their goals for accuracy, efficiency and patient care.”
