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.
一条纤维索带起始于小指尺侧缘小指展肌附着处附近，长约60毫米，宽3毫米，质地坚韧。纤维索带与小指的纵轴平行，位于手指关节屈伸轴掌侧的骨嵴水平。在近端，该索带接收来自近节指骨基部骨膜、蹼状韧带尺侧端以及A1滑车假腱性纤维的纤维。在远端，指索带与格雷森（Grayson）和克莱兰（Cleland）皮肤韧带相连。该索带还与屈肌腱鞘、神经血管束和皮肤相连。有时这些索带会参与杜普伊特伦挛缩症（Dupuytren's contracture）。
