Trigger finger release at The London Sports Injury Clinic
The tendon that bends your finger has a bump in it. When you bend your finger fully, the bumpy part of your tendon comes out of its sheath at the base of your finger. When you try to straighten your finger the bump catches on the tendon sheath, stopping the tendon from sliding smoothly back.We aim to release your tendon so that you can straighten your finger easily. We cannot remove the bump from your tendon so instead we cut open the entrance to the tendon sheath. This gives your tendon more room to move back and forth. If your symptoms are mild, we can try an injection of steroid around your tendon.
