Dorsal intercarpal ligament

Last revised by Assoc Prof Craig Hacking on 25 Nov 2020

The dorsal intercarpal ligament is one of the extrinsic wrist ligaments.

Gross anatomy

The dorsal intercarpal ligament has a horizontal orientation, however, together with the dorsal radiotriquetral ligament, it is said to have a zig-zag configuration.

It runs from the dorsal tubercle of the triquetrum to the dorsal groove of the scaphoid. It also has attachments to the lunate and, in 50% of individuals, the trapezium.

Its function is to provide stability to the carpal bones, in particular contributing to scapholunate stability. It prevents scapholunate dissociation in a weight-bearing upper limb.
