Flexor Tenosynovitis (Trigger Finger)
Trigger finger limits finger movement. When trying to straighten your finger, it will lock or catch before popping out straight. This is caused when the flexor tendon (the cord that connects the muscle to bone) becomes irritated as it slides through the tendon sheath tunnel (or finger pulley). As the tendon becomes more and more irritated, it may thicken and nodules may form, making its passage through the tunnel more difficult. The tendon sheath may also thicken, causing the tunnel opening to become smaller. Symptoms include a tender lump in your palm, swelling, a catching or popping sensation, and/or pain when bending or straightening your finger. The stiffness and catching tend to be worse with inactivity, such as when you first wake up in the morning. The goal of treatment is to reduce inflammation and return finger function and range of motion. The doctors at the hand institute are currently performing a state of the art procedure, offering a quick and painless technique in the office to treat trigger finger.
