Tenon Medical announces completion of initial case series using Catamaran system

Tenon Medical (TNON) announced the completion of an initial case series utilizing the Catamaran SI Joint Fusion System to immobilize & stabilize the SI Joint providing added support at the base of a lumbar or thoracolumbar fusion. The case series was completed by Andrew Trontis, MD from Progressive Spine & Orthopaedics in Englewood, New Jersey. As announced previously by the Company, the Catamaran recently received an expanded indication for use from the U.S. Food and Drug Administration. The Catamaran is now approved to augment immobilization and stabilization of the SI joint for patients undergoing sacropelvic fixation as part of a lumbar fusion. “As an orthopedic spine surgeon managing complex spinal pathology, I am always looking for innovations that deliver long-term value to my patients,” said Trontis. “Integrating Catamaran into spinal fusion constructs has meaningfully enhanced my surgical approach – offering robust stabilization at the base of the fusion without adding significant morbidity, blood loss, or operative time. By securing this foundation early, we can reduce the risk of future sacroiliac joint pain or pelvic instrumentation failure, ultimately supporting more durable outcomes.”
