Absence of flexor digitorum superficialis tendon in the little finger is not associated with decreased grip strength

Abstract

We examined the little finger in 402 normal subjects for the presence or absence of the flexor digitorum superficialis. All subjects also had their grip strength measured. No statistically significant difference was seen in the grip strength measurements between subjects who had a flexor digitorum superficialis tendon to the little finger and those who did not. This study demonstrates that absence of the flexor digitorum superficialis to the little finger is not associated with decreased grip strength. The implications of this in terms of repair of the flexor digitorum superficialis of the little finger are considered.
