The intermetacarpal joints are in the hand formed between the metacarpal bones. The bases of the second, third, fourth and

fifth metacarpal bone The fifth metacarpal bone (metacarpal bone of the little finger or pinky finger) is the most medial and second-shortest of the metacarpal bones. Surfaces It presents on its base one facet on its superior surface, which is concavo-convex and artic ...

s articulate with one another by small surfaces covered with cartilage. The metacarpal bones are connected together by dorsal, palmar, and interosseous ligaments. * The dorsal metacarpal ligaments (''ligamenta metacarpalia dorsalia'') and palmar metacarpal ligaments (''ligamenta metacarpalia palmaria'') pass transversely from one bone to another on the dorsal and palmar surfaces. * The interosseous metacarpal ligaments (''ligamenta metacarpalia interossea'') connect their contiguous surfaces, just distal to their collateral articular facets. The synovial membrane for these joints is continuous with that of the

carpometacarpal joint The carpometacarpal (CMC) joints are five joints in the wrist that articulate the distal row of carpal bones and the proximal bases of the five metacarpal bones. The CMC joint of the thumb or the first CMC joint, also known as the trapeziometaca ...
