We recently operated on a patient with TF who did not respond to conservative treatment. At surgery, we found an anomalous insertion of the fourth lumbrical muscle to the A1 pulley. This insertion was observed to cause mechanical narrowing of the pulley due to a pulling effect by the muscle, which was relieved by resection.<\/jats:p>\n                  <\/jats:sec>\n
