The transverse carpal ligament is a wide ligament that runs across the hand, from the scaphoid bone to the hamate bone and pisiform.
It is the volar ligament that connects the pisiform to the hamate.
The capitate, lunate, hamate and triquetrum are bounded together in this procedure and the scaphoid is excised.
About one-third of lunate bones do not possess a medial facet, meaning they do not articulate with the hamate bone.
The "inferior surface", directed lateralward, is concave, sinuously curved, and smooth for articulation with the hamate.
The third metacarpal is connected to the trapezium, to the capitate, and to the hamate.
Occasionally, the joint between the hamate and the fourth and fifth metacarpal bones has a separate synovial membrane.
The lunate also articulates on its distal and medial surface with the hamate bone.
