Trigger finger, refers to chronic aseptic inflammatory changes of finger tendon sheath caused by mechanical friction. It is common in housekeepers and workers who heavily use hands. It is more common in older women. The onset is slow. Main symptoms are palm pain near fingers and limited mobility of fingers. As tendon sheath narrowing aggravates and enlargement of tendon after compression, the enlarged part will be unable to slide through the narrowed tendon sheath, so fingers will remain in either extension or flexion position. Non-surgical therapy is generally effective. If non-surgical therapy fails, surgery can be done to cut open the tendon sheath.
