Technologies Submits FDA 510(k) for Silicon Nitride Foot & Ankle Medical Devices
Material Science Meets Surgical Precision in Groundbreaking New Platform in Reconstructive Foot & Ankle Surgery Market
LAKE CITY, Utah - July 22, 2025 - SINTX Technologies, Inc. (NASDAQ: SINT) ("SINTX" or the "Company"),
an advanced ceramics innovator specializing in silicon nitride (Si N ) for medical applications, today announced the submission
of a 510(k) premarket notification to the U.S. Food and Drug Administration (FDA) for its novel silicon nitride osteotomy wedges-marking
the official entry into the foot and ankle reconstruction market. These next-generation implants blend cutting-edge biomaterials science
with surgical precision and are designed to elevate standards in orthopedic procedures.
devices are manufactured from SINTX's proprietary medical-grade silicon nitride, a biomaterial with a proven clinical track record
of over 50,000 spinal interbody fusion devices implanted since 2008. With this submission, SINTX is extending the success of Si N
beyond the spine and into the global foot and ankle fusion market, currently valued at approximately $750.5 million and which is expected
to grow to $1.38 billion by 2032 according to industry research.
Advantages of Silicon Nitride
a clinical standpoint, Si N is uniquely positioned among biomaterials to solve several of the most pressing challenges in
orthopedic reconstruction:
| Pro-osteogenic : Unlike PEEK or titanium, Si N has been shown to actively promote bone cell adhesion, proliferation, and differentiation. In vivo and in vitro studies have shown enhanced osseointegration and fusion potential due to the material's inherent surface chemistry and nanotopography. | ||
| Antimicrobial Without Additives : Si N has been shown to inhibit bacterial colonization and proliferation-including several antibiotic-resistant strains -through inherent surface chemistry without a supplemental coating. This is particularly critical in foot and ankle procedures where occurrences of hardware-related infections persist despite current best practices. | ||
| Radiographic Clarity : Si N implants are intrinsically radiolucent with clearly visible boundaries on X-ray and CT scans. This facilitates precise intraoperative placement and clear post-operative evaluation of bone healing-unlike metal implants which obscure fusion assessment. |
believe Si N is the ideal orthopedic biomaterial for fusion procedures where infection risk, healing rate, and long-term
stability are paramount," said Eric Olson, CEO of SINTX Technologies.
Innovation: Proprietary Designs with Disposable Instrumentation
parallel with biomaterial excellence, SINTX has engineered proprietary implant geometries and disposable instrumentation to elevate surgical
| Implant Geometry : The family of wedges were developed in collaboration with leading foot and ankle surgeons to optimize for biomechanical correction, surface area contact, and ease of insertion. | ||
| Disposable Instrument Set : At full launch we anticipate each implant system to be paired with a sterile, single-use instrument kit to enhance maximum surgical efficiency and sterility. This potentially leads to a reduction in intraoperative delays, elimination of reprocessing errors, and a decrease in OR turnover time-benefits that hospitals and ambulatory surgery centers alike will value. |
combined the novel clinical advantages of silicon nitride with intuitive implant designs and single-use instrumentation to deliver a
truly differentiated solution," said Lisa Marie Del Re, Chief Commercial Officer of SINTX Technologies. "This approach goes
beyond innovation in material science. We've reimagined the surgical experience, striving to improve outcomes, enhance efficiency,
and deliver stronger economic value across the care continuum."
Launch and Financial Outlook
| The FDA submission is backed by over a decade of clinical and preclinical data on SINTX's Si N biomaterial, including peer-reviewed publications, biocompatibility studies, and documented fusion success. | ||
| With compelling clinical advantages and meaningful input from high-volume reconstructive surgeons, the company anticipates strong early adoption of its foot and ankle portfolio. This launch represents a key growth catalyst for SINTX, with the potential to drive meaningful revenue through broader market penetration and increasing procedural demand across both hospital and ambulatory surgery center settings. |
Value to All Stakeholders
| For Patients : The design and material properties of our silicon nitride implants are intended to support successful bone fusion and to reduce infection risk; key considerations in recovery and long-term outcomes. | ||
| For Surgeons : Engineered for enhanced intraoperative visualization and ease of use, our system integrates advanced implant geometry with streamlined instrumentation to support surgical precision and procedural consistency. | ||
| For Providers and Stakeholders : The combination of sterile, single-use kits and differentiated biomaterial technology offers operational efficiencies and clinical distinction, positioning this platform for strong alignment with evolving value-based care models and increased procedural demand. |
is not just another foot fusion product line-this is a platform," added Olson. "A platform built on a proven material,
rooted in over a decade of clinical experience, and refined with thoughtful surgical design. We believe SINTX is redefining what's
possible in orthopedic advancements."
implants will be manufactured at SINTX Technologies FDA audited and ISO certified manufacturing facility and distributed under the company
name SiNAPTIC Surgical. SiNAPTIC was acquired by SINTX on July 1, 2025.
