The dorsal intercarpal ligament consists of a series of fibrous bands that extend transversely across the dorsal surfaces of the carpal bones, ...
The palmar intercarpal ligaments are also two, connect the scaphoid and lunate, and the lunate and triangular; they are less strong than the dorsal, and placed very deeply behind the Flexor tendons and the volar radiocarpal ligament. The interosseous intercarpal ligaments are two narrow bundles, one connecting the lunate with the scaphoid, the ...
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 ...
The extensor retinaculum (dorsal carpal ligament, or posterior annular ligament) is a thickened portion of the antebrachial fascia that holds the tendons of the extensor muscles in place. [1] It is located on the back of the forearm , just proximal to the hand . [ 2 ]
The collateral ligaments originate on depressions on each side of the metacarpal heads dorsal to axis of rotation. From there, they extend obliquely and distally to their insertions onto tubercles at the base of the proximal phalanx. The accessory collateral ligaments originate volar to the collateral ligaments and are inserted on the palmar ...
The midcarpal joint is the S-shaped joint space separating the proximal and distal rows of carpal bones. The intercarpal joints, between the bones of each row, are strengthened by the radiate carpal and pisohamate ligaments and the palmar, interosseous, and dorsal intercarpal ligaments.

Joints of the hand, X-ray Interphalangeal ligaments and phalanges. Right hand. Deep dissection. Posterior (dorsal) view. The PIP joint exhibits great lateral stability. Its transverse diameter is greater than its antero-posterior diameter and its thick collateral ligaments are tight in all positions during flexion, contrary to those in the metacarpophalangeal joint.
