The complex anatomy of the hand consists of 27 bones, along with muscles, joints, tendons, nerves, and ligaments. If any of these structures become injured, pain and loss of function can put a damper on almost all activities. In other words, you rely on the use of your hands for almost everything you do on a daily basis. However, when you have constant pain and discomfort in your hands or wrists, these simple tasks become more difficult and uncomfortable. Some conditions, such as trigger finger, are not only painful, but also affect your appearance and function.
Any hand or wrist problem causing pain, swelling, discoloration, numbness or a tingling sensation, or abnormal shape, that persists for more than two or three days should be evaluated by your orthopedist to establish the cause, and allow treatment as early as possible. Early diagnosis and early treatment generally give the best results.
So, you notice that one day when making a fist, you try to straighten your fingers afterwards, when one catches when attempting to bring it back into a straight position, causing pain. After you go to a doctor to check it out, they diagnose you with a condition called trigger finger, caused by overuse.
Trigger finger, known medically as stenosing tenosynovitis, is a condition that causes pain, locking, popping or clicking of the fingers or thumb when the hand is opened or closed. Muscles in your forearm attach to tendons that run all the way down to the bones at the ends of your fingers. These muscles are what help you bend your fingers into a fist.
The reason why we are able to open and close our hand is due to our tendons being pulled close to the bones of the fingers by pulleys. If these pulleys become too thick, stiff, tight or swollen, commonly due to inflammation, this causes the finger to “trigger” or get stuck when trying to straighten your fingers after being in a fist. Therefore, if the tendon cannot glide freely, trigger finger occurs.
Symptoms of trigger finger can occur differently for people, which is why it is not always easy to identify the cause. In its early stages, trigger finger can cause pain on the palm of your hand, or on the back side of a finger. Trigger finger causes inflammation, creating symptoms of stiffness and swelling. As the muscles and tendons in our fingers give us the ability to move, when someone is diagnosed with trigger finger, there can be a painful snapping sensation when opening and closing the hand. Often one of our fingers can get stuck in a certain position, making it painful and impossible to straighten or bend it.
