Tennon Medical, Inc. announced completion of the first patients treated with the Company's newly released JIB Instrument Kit. Matthew T. Davies, MD, a board-certified Neurosurgeon from Orthopedic Associates in Duluth, Minnesota successfully treated the first three patients with the JIB kit at Lakewalk Surgery Center on August 31, 2023. Dr. Davies is a recognized leader in the diagnosis and treatment of the SI Joint, utilizing innovative minimally invasive SI Joint fusion procedures to treat painful SI Joint dysfunction and degenerative sacroiliitis.

He has performed more than 300 SI Joint fusion procedures and recently incorporated the Catamaran implant into his SI Joint fusion treatment algorithm. The JIB Kit is a next generation instrument set utilized to implant the Company's Catamaran Fixation Device during a SI Joint fusion procedure. The JIB Kit is used with the current Catamaran instrument tray for accessing the implant site, implant delivery, and expediting bone graft removal and insertion into the Catamaran implant.

The JIB Kit incorporates physician feedback gained from early surgeries and provides a lower profile access portal designed to enhance stability, and tools for improved graft handling. It is estimated that over 30 million American adults suffer from chronic lower back pain and that a significant percentage of these cases include an SI Joint disruption component. The SI joints are located between the iliac bones and the sacrum, connecting the spine to the hips.

Caused most frequently by trauma or degeneration, pain from the SI Joint often goes misdiagnosed. Published clinical studies have shown that 15% to 30% of all chronic lower back pain is associated with the SI Joint.
