(NASDAQ:TNON) ("Tenon" or the "Company"), a company redefining care for patients with sacro-pelvic disorders, today announced the completion of the initial alpha cases with its new Quickstep Decorticator. Quickstep is the latest advancement in a line of technology that makes up Tenon's next-generation SI joint fusion systems. The Company is targeting full market release of Quickstep in the first quarter of 2027. The alpha cases follow the recent full market launch of the Company's titanium 3D-printed lateral screw as part of the SImmetry+ SI Joint Fusion System. Decortication: A Foundational Principle of True Arthrodesis Achieving an authentic arthrodesis - a true biological fusion of bone across a joint, rather than fixation alone - has long depended on a well-defined set of surgical principles. Grounded in the AO principles that have guided orthopedic surgery for decades, these include thorough preparation of the joint surfaces, bone grafting, and rigid fixation that stabilizes the joint while a fusion response develops over time. Joint preparation through decortication is intended to remove cartilage and the hard cortical surface of the joint to expose bleeding bone. This process releases the cellular and vascular elements that drive bone healing and creates a receptive bed for fusion. Without it, an implant may stabilize the SI joint mechanically, but the conditions that allow for bridging bone across the joint are significantly diminished. The Quickstep Decorticator is designed to streamline the joint decortication step of the SImmetry+ procedure, a key step in prepoaring the joint for fusion. By simplifying instrumentation and reducing surgical steps, Quickstep is intended to help physicians work more efficiently in the operating room while remaining true to the AO-based fusion principles that underpin the SImmetry+ System: joint preparation, bone grafting, and rigid fixation. The company believes that procedural efficiency, ease of use and repeatability are key drivers of physician adoption, and the Company views Quickstep as an important step in expanding the SImmetry+ user base. Key features of the Quickstep include: Drill and decorticate through one instrument. Surgeons can drill and decorticate the SI joint through a single instrument, reducing the need to switch between separate tools and consolidating multiple procedural steps into fewer ones. Interchangeable cutting blades in multiple sizes. The system includes a choice of interchangeable cutting blades in various sizes, allowing surgeons to tailor decortication to the individual patient's anatomy. Designed to support fusion. Quickstep is designed to decorticate the SI joint to help evoke a fusion response with the system's 3D-printed titanium implants, whose porous surface matrix is designed to facilitate bone ongrowth directly on the implant surface. "Placing a screw across a symptomatic SI joint has shown to provide immediate stabilization and reduce painful micromotion of the joint; however, achieving a long-term arthrodesis should be the goal every time we treat SI joint dysfunction, just as it is in spinal fusion. Decortication of the SI joint is a critical step in achieving a lasting arthrodesis, but has historically been difficult to perform consistently and efficiently," said Sunil Panchal , MD, Founder and CEO of the National Institute of Spine and Pain in Tampa, Florida . "In my initial alpha cases with Quickstep, drilling and decorticating through the same instrument along a single trajectory eliminated several instrument exchanges and streamlined the workflow under fluoroscopy. The interchangeable cutting blades allowed me to select the most appropriate size cutting element for my patient's specific SI joint anatomy, so I could achieve thorough intra-articular preparation tailored to that joint." "The Quickstep technology reflects our continued investment in the SImmetry+ platform and our commitment to giving physicians the tools they need to achieve consistent outcomes for their patients," said Steven M. Foster , President and Chief Executive Officer of Tenon. "Quickstep is intended to make the procedure more efficient without compromising the fusion principles at the core of SImmetry+. By giving physicians a simpler, streamlined decortication step, we believe Quickstep may further support long-term adoption of the SImmetry+ System. We look forward to feedback from our alpha physicians as we prepare f
