metacarpal ligament

From the sides of these processes offsets are attached to the transverse metacarpal ligament.

It differs from the transverse metacarpal ligament in that it connects the metatarsal to the others.

At full flexion, the transverse metacarpal ligament restricts the interossei.

Transverse metacarpal ligament can refer to:

The deep transverse metacarpal ligament stabilises the mobile parts of the palmar arch system.

All interossei pass dorsal to the transverse metacarpal ligament but slightly volar to the flexion-extension axes of rotation of the MP joints.

The first annular pulley (A1 pulley), near the head of the metacarpal bone, lies in the flexor groove in the deep transverse metacarpal ligament.

The interosseous metacarpal ligaments (ligamenta metacarpalia interossea) connect their contiguous surfaces, just distal to their collateral articular facets.

The deep transverse metacarpal ligament is a narrow fibrous band which runs across the palmar surfaces of the heads of the second, third, fourth and fifth metacarpal bones, connecting them together.

The superficial transverse metacarpal ligament is a ligament of the Intermetacarpal articulations which runs beneath the deep transverse metacarpal ligament.

In the MCP joints, the four volar plates of the fingers and the capsules within which they lie are blended with and interconnected by the deep transverse metacarpal ligament which ties the metacarpal heads together.

When the MP joints are flexed, the transverse metacarpal ligament enhances the function of the distal interossei by acting as a pulley and preventing them from becoming slack, further increasing the effectiveness of IP extension.

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.
