Study Notes
Distal Row Carpal Bones
- Trapezium: Located beneath the thumb, features a tubercle for muscle and ligament attachment.
- Trapezoid: Resembles the trapezium, but positioned slightly closer to the thumb's inner side.
- Capitate: Largest carpal bone, dome-shaped. The median nerve passes near it.
- Hamate: Wedge-shaped, on the medial side of the hand. It has a hook for attachment of the flexor carpi ulnaris and flexor retinaculum. The ulnar nerve travels beside the hook.
