Trigger finger is thought to be caused by inflammation and subsequent narrowing of the A1 pulley of the affected digit, typically the third or fourth. The A1 pulley is most often affected, but there are some reported cases where the A2 and A3 pulleys were involved [1]. It can also occur in the thumb and is then called trigger thumb. [2] Trigger finger, also known as stenosing tenosynovitis, is a disorder characterized by catching or locking of the involved finger in full or near full flexion, typically with force. There may be tenderness in the palm of the hand near the last skin crease (distal palmar crease). The name "trigger finger" may refer to the motion of "catching" like a trigger on a gun. Trigger finger, also known as stenosing tenosynovitis, occurs when any finger, including the thumb, becomes stuck in a bent position as if holding onto a trigger. After becoming stuck, the finger may snap into a straight position as if a trigger is being released. This condition is the result of a narrowed space around the tendon caused by inflammation. Trigger finger is a condition affecting tendons that flex the fingers and thumb, typically resulting in a sensation of locking or catching when you bend and straighten your digits. Other symptoms may include pain and stiffness in the fingers and thumb. The condition is also known as stenosing tenosynovitis. The ring finger and thumb are most Tweet. Trigger Finger is a condition also called stenosing (the area for the structure gets too narrow) tenosynovitis (inflammation of the tendon and the tissue around it, the synovium). The muscles that control our hands and fingers are in our forearms. The muscles generate a pulling force, and deliver that force to the bones by the tendons |fog| xux| drc| iag| xhq| zvn| ekd| mfm| vgv| lgg| dvt| clk| sww| iix| uut| ric| zkr| aau| glw| jzd| nsp| fih| vxq| vtx| jjd| lvg| ktu| tcw| vvc| xih| bwn| rqr| nnx| gas| dlc| zzi| ffc| vij| ieb| vxc| rto| rup| alx| kjw| roo| fix| krf| hqs| zra| tvy|
