Tenon Medical

Tenon Medical is developing a minimally invasive approach to treat lower back pain originating in the sacroiliac (SI) joint.

The SI joint is an underappreciated cause of low back pain. It is more common in presence of trauma, pregnancy, or certain athletes. Back pain may be decreased or eliminated through stabilization or fusion of certain skeletal joints of the body, such as the SI joint of the spine.

Americans spend $50 billion a year on lower back pain. Lumbar pain is the most common cause of job related disability and a leading contributor to missed work. In the US, lower back pain is the number one reason for individuals under the age of 45 to limit activity. Lower back pain is the second most prevalent complaint seen in physician offices and the third leading cause of surgery.

Leading orthopedic publications state that anywhere from 15% to 25% of all lower back pain originates from the SI joint. There is also a group of female post pregnancy patients with problems and instability related to SI joint pathology that could be treated with fusion. Important soft tissue structures, such as ligaments, vessels, and nerves surround the SI joint, making intervention challenging.

The Catamaran addresses this unmet clinical need by providing a less invasive way to stabilize the SI joint without compromising the important surrounding soft tissue structures.
