title: [A bilateral and symmetric anatomic variation of a lombrical muscle causing a trigger finger].
abstract: Trigger finger is a very common disease. The vast majority of trigger fingers are primary idiopathic trigger ﬁngers. We report the case of a bilateral and symmetric triggering of the fifth finger secondary to an anatomical variation of the lumbrical muscle. This lumbrical muscle arose from the flexor digitorum superficialis instead of the flexor digitorum profundus as is usual. To our knowledge, this is the third published case of trigger finger caused by an anatomical abnormality of a lumbrical muscle.
