Anatomical Relations
The vincula tendinum are synovial folds that connect the flexor digitorum tendons to the adjacent bone.
The vincula tendinum are divided, according to their length, into vincula brevia and vincula longa. There are typically two vincula brevia and two vincula longa that attach to each tendon; however, the numbers are variable.
The vincula brevia join the flexor digitorum superficialis to the proximal interphalangeal joint and the flexor digitorum profundus to the distal interphalangeal joint.

Structure
The synovial folds (vincula tendinum) contain the blood vessels that supply the tendons.
Function
The vincula tendinum allow the tendons to glide within the fibrous tendon sheaths.
