"A trigger finger is a condition that causes pain, stiffness and a sensation of locking or catching when you try to bend or straighten your finger. It is also called “Stenosing tenosynovitis”. Most often the ring finger and thumb are affected. But this can occur in any finger. When it affects the thumb, it is called Trigger Thumb. Trigger finger is the most common cause of hand pain and disability......
.....Trigger finger is caused by inflammation and thickening of the flexor tendons, the tendons that allow the fingers to bend and straighten. A trigger finger develops over time causing the tendon to glide abnormally. When a swollen tendon develops a nodule, it causes the tendon to get stuck as you try to open and close the finger, causing a sensation of catching or popping that can be very painful."
"As with most injuries, proper diagnosis and early intervention are key to successfully managing a UCL tear or disruption. The patient should be made aware of the seriousness of this diagnosis and must understand the importance of careful follow through with the treatment regime.
Initial treatment begins with icing, NSAID’s (non-steroidal anti-inflammatory drugs) to reduce pain and inflammation, and elevation of the hand to minimize swelling. Splints that stabilize and immobilize the thumb and/or wrist are required to facilitate healing and are generally worn for 4 to 6 weeks to allow adequate healing to take place."
