The ulnar triquetral ligament is located in a portion of your wrist opposite from your thumb. Also known as the UT ligament. It can be injured in a way that usually doesn’t show up on x-rays or MRIs. If this ligament is twisted, it can split and tear lengthwise like a stock of celery. The exposed surface of the UT ligament gets irritated and inflamed. And this causes pain during use. To correct the problem, surgeons shave away the damaged tissue and then suture the sides of the ligament back together.
