| ATLANTA, Aug. 18, 2020 /PRNewswire/ -- MedShape Inc., the industry leader in innovative NiTiNOL and other advanced material technologies, today announced that it has received a Technology/Therapeutic Development Award funded by the Department of Defense Peer Reviewed Medical Research Program (PRMRP) to assist in the research and development of a dynamic compression fusion device using superelastic nickel titanium (NiTiNOL) for use in diabetic foot limb salvage surgery. The funding award from PRMRP includes $2.6M to complete the research milestones over the next 3 years. Nearly 5 million military Veterans suffer from diabetes mellitus with 15,000 of those also diagnosed with Charcot Foot,1,2 a painless, progressive, disease that results in the breakdown of the bones in the midfoot. Diabetic patients reportedly are 10-20 times more at risk of needing an amputation compared to non-diabetics4. In addition, those who undergo an amputation are 3 times more likely to die within 1 year of surgery compared with patients who are successfully treated through other surgical options. Given the high mortality rate, orthopaedic surgeons strive to salvage the limb with alternative surgical treatments. Currently, intramedullary (IM) screws are placed across the midfoot in an attempt to stabilize and realign the foot. However, these “beaming” devices undergo repetitive and significant loading, with 25-60% of the current devices experiencing failure, often due to loss of compressive force, implant loosening and axial migration.3,4 Through the support of the DOD research grant, MedShape, in collaboration with limb salvage specialists Dan Latt, MD/PhD (University of Arizona) and Naohiro Shibuya, DPM (Texas A&M College of Medicine), will explore the development of novel devices that maintain dynamic compression and effectively stabilize the foot in an effort to preserve the limb in the diabetic Charcot Veteran population. By leveraging MedShape’s patented NiTiNOL platform technology, devices can be designed to adapt and respond to specific changes in the biological environment that occur during healing while also effectively load-sharing with the bone to reduce stress risers on the device that lead to device failure and additional surgery. “Standard midfoot fusion devices should be robust enough to withstand weight-bearing and also able to apply compression for bone-on-bone healing. However, standard devices don’t work well for diabetic patients with Charcot neuroarthropathy because their midfoot bones have deteriorated, which puts them at risk for amputation. Surgeons need a better solution, and we believe that our dynamic compression technology can be developed to address this dire need”, said David Safranski, PhD, Director of Basic Research at MedShape, Inc. “Due to MedShape’s extensive experience in smart (NiTiNOL-based) orthopaedic devices, we are uniquely qualified to address this clinical challenge with our Veterans. The PRMRP’s support is critical for our team to develop these next-generation medical devices.” The clinical use of MedShape’s internal NiTiNOL technology has already been successfully demonstrated through the company’s DynaNailÒ TTC Fusion System. Ten peer-reviewed publications on the DynaNail report significantly improved clinical outcomes when treating high-risk patient populations such as diabetics and those with Charcot neuroarthropathy,5-7 suggesting the utility of the technology in other challenging fusion applications. Last month, MedShape received a small business innovation research grant to develop novel MTP replacement implants, thus reinforcing MedShape’s continued commitment to advancing biomaterials research to develop state-of-the-art medical solutions.
