Dr. Fall introduces the device into the carpal tunnel through a single limited incision in the wrist flexor crease. Viewing the deep side of the transverse carpal ligament (flexor retinaculum) under direct visualization at the tip of the instrument, the surgeon elevates the blade to cut the ligament as the instrument is withdrawn.

The Centerline technique incorporates improved safety features compared to other ECTR devices that have been used for over 20 years and eliminates rotational movements while offering superior visualization. The thumb trigger pull is synergistic, increasing steadiness and facilitating control. The Centerline endoscopic carpal tunnel release system attaches to a standard video camera and light source.
