The intermetacarpal joints

The intermetacarpal joints are plane synovial joints between the adjacent sides of the bones of the second and third, third and fourth, and fourth and fifth metacarpals. The joints are closed anteriorly, posteriorly and distally by palmar and dorsal metacarpal ligaments, and interosseus ligaments respectively, that pass transversely between the adjacent bones. Their  joint spaces are continuous with the common carpometacarpal joint distally. The blood and nerve supply to these joints is similar to that for the common carpometacarpal joint. Movements at these joints will accompany movements of the metacarpals against the distal row of carpal bones. In accessory movements, a small amount of anteroposterior gliding can be produced between any two metacarpal bases by appropriately applied pressure.
