TCTR technique and procedure: What to expect

The patient enters the procedure room and made comfortable. A local anesthetic numbs the arm.

Ultrasound technology precisely maps the anatomy of the wrist. It is used to guide a thin needle through the base of the hand underneath the transverse carpal ligament and out through the wrist. Through this needle, a thin, smooth thread is fed.

A second needle is inserted through the wrist in a similar fashion and is guided by ultrasound over the transverse carpal ligament. The same thin, smooth thread is looped out of this needle and out through the original needle site.

The thread surrounds the transverse carpal ligament and is manipulated in a back-and-forth motion to divide the ligament and release pressure on the median nerve.

Once the procedure is complete, the thread is removed and the wrist is bandaged. Some patients need only two small adhesive bandages placed over the needle sites. The entire TCTR procedure often takes fewer than 10 minutes.
