The interosseous intercarpal ligaments are two narrow bundles, one connecting the lunate with the scaphoid, the other joining it to the triangular.

The dorsal ligaments are three in number, extend transversely from one bone to another on the dorsal surface, connecting the greater with the lesser multangular, the lesser multangular with the capitate, and the capitate with the hamate.

In the latter condition the joint between the hamate and the fourth and fifth metacarpal bones has a separate synovial membrane.

The synovial cavities of these joints are prolonged for a short distance between the bases of the metacarpal bones.
