The triangular fibrocartilage complex (TFCC) is responsible for the use of our opposable thumbs and wear or injury can lead to wrist pain and swelling. In many cases, the recommended treatment for chronic TFCC problems is a surgery that involves shortening the ulna, the arm bone leading to the wrist, in order to reduce pressure. Research shows that this surgery, far from being a helpful long-term solution, actually leads to an increase in negative forces in the wrist that lead to future injuries. Beyond that, significant complications have been found in nearly 50% of patients following surgery.
