Trigger Finger Release
Trigger finger, also known as stenosing tenosynovitis, is a painful catching of a digit with attempted active extension. This occurs most commonly at the level of the A1 pulley because of a disparity in the size of the flexor tendons and the surrounding tendon sheath, resulting in interference with smooth tendon gliding. The pathologic changes observed with this disorder include stenosis of the fibrous flexor tendon sheath due to chronic inflammation as well as a reactive nodule within the flexor digitorum superficialis tendon.
