What is Trigger Finger?
Trigger Finger is also known as Stenosing Tenosynovitis. It occurs when the tendons that help bend, or "flex", a finger get inflamed or thickened leading to scar tissue build up surrounding the tendon. This causes the tendon to get stuck or "trigger" as it passes through smooth tunnel systems called "pulleys". As a result, the finger can become painful and cause a locking or clicking sensation. Some people also report being unable to fully straighten the finger.
How do we treat it?
Many people respond well to a trial of corticosteroid injections. These injections help soothe the inflammation surrounding the tendon and some get complete relief of their symptoms. If symptoms recur or worsen, then surgery may be considered.
What is the surgery?
Surgery for trigger finger involves making a small incision on the palm of the hand. The inflamed tendon is found and the tunnel, or "pulley", it is getting stuck in is opened. This allows the tendon to pass freely. Often times scar tissue surrounding the tendon is also removed. This is performed as "same-day-surgery" and total time spent in the hospital is typically only a few hours. That way, you can be back in the comfort of your own home quickly.
