[Clinical anatomy of the digital connective tissue cord of the ulnar side of the little finger].

A fibrous cord with a length of nearly 60 mm and a width of 3 mm consistency starts near the insertion of the abductor digiti minimi muscle at the ulnar border of the little finger. The fibers pass parallel to the longitudinal direction of the little finger and at the level of the osseous ridges on the palmar side of the flexion-extension axis of the finger joints. Proximally the cord receives fibers from the periosteum at the base of the proximal phalanx, from the ulnar end of the natatory ligament, and from the pretendinous fibers of the A1 pulley. Distally the digital cord has connections to the cutaneous ligaments of Grayson and Cleland. The cord also joins the flexor tendon sheath, the neurovascular bundles, and the skin. Sometimes these cords are involved in Dupuytren's contracture.
