complex joint between the proximal and distal carpal bones of the wrist
permits flexion, extension, adduction and abduction of the wrist
receives vascular supply from posterior carpal branches of the radial and ulnar artery and the anterior interosseous artery
The midcarpal joint, as implied by the name, is present between the proximal and distal carpal bones of the wrist. It is formed of two saddle joints; first between the capitate, hamate and scaphoid, lunate, triquetrum, second between trapezium, trapezeoid and scaphoid 1.
The joint, although consisting of two saddle joints, is itself a condylar joint implying movement in two planes: flexion/extension and abduction/adduction of the wrist. It is the primary joint involved in radial and ulnar deviation of the wrist 2.
Carpometacarpal joint of the medial four metacarpals communicates with midcarpal bones in a single synovial cavity 3.
The midcarpal joint is stabilized by the palmar and dorsal midcarpal ligaments.
The midcarpal joint receives vascular supply from posterior carpal branches of the radial and ulnar artery and the anterior interosseous artery (branch of the ulnar artery) 1.
The innervation for the midcarpal joint comes from the deep terminal branch of the ulnar nerve and the anterior interosseous branch of the median nerve. The posterior interosseous branch of the radial nerve may also be involved 1.
