Does the Teno Fix® impede gliding of the tendon under the pulley system?
The Teno Fix® device is designed to glide smoothly under the zone II pulley system of the digit. Each anchor is 3.5mm long by 2mm in diameter. This mass is offset by the unique ability to capture the collagen fibers and compress them between the coil and the core. The natural taper of the Teno Fix® anchor along with the intratendinous placement allow for minimal distention of the tendon decreasing the chance of an increased work of flexion or triggering of the tendon on the pulley system. The Teno Fix® device also requires a single 2-0 stainless steel suture to pass through the center of the injury reducing the bulking at the injury when compared directly to the number of sutures passing through the center of the injury in a standard suture repair. There should be no bunching at the repair site in a Teno Fix® repair due to the use of stainless steel which has no elastic properties as opposed to typical suture repairs utilizing polypropylene or nylon sutures that are expected to stretch
