It's important to distinguish association and causation. The cause of<unk>  is unclear but several causes have been proposed. It has also been called stenosing tenosynovitis (specifically digital tenosynovitis stenosans), but this may be a misnomer, as inflammation is not a predominant feature. Some speculate that repetitive forceful use of a digit leads to narrowing of the fibrous digital sheath in which it runs, but there is little scientific data to support this theory. The relationship of<unk>  to work activities is debatable and there are arguments for and against a relationship to hand use with no experimental evidence supporting a relationship.
