The third metacarpal bone (metacarpal bone of the middle finger) is a little smaller than the second.
The dorsal aspect of its base presents on its radial side a pyramidal eminence, the styloid process, which extends upward behind the capitate; immediately distal to this is a rough surface for the attachment of the extensor carpi radialis brevis muscle.
The carpal articular facet is concave behind, flat in front, and articulates with the capitate.
On the radial side is a smooth, concave facet for articulation with the second metacarpal, and on the ulnar side two small oval facets for the fourth metacarpal.
