Trigger Finger, also known as stenosing tenosynovitis may cause a popping or snapping noise when bending or straightening your finger, and in extreme cases, the finger may become fully locked in a bent position. This occurs when an inflammatory nodule in the tendon gets caught beneath a pulley in the palm, causing pain, inflammation and stiffness which can be permanent.

Procedure

Surgical correction may be recommended. This surgery is usually performed in an operating room as an outpatient... A small incision, about a half inch long, is made to the affected finger pulley to stop the nodule from catching. The surgeon then releases the tight portion of the flexor tendon sheath. The incision is then closed with a couple of sutures and covered with a sterile dressing.
