carpal bones

Your wrist is made up of eight small bones called the carpal bones, or the carpus. These irregularly shaped bones join your hand to the two long forearm bones: the radius and ulna. The carpal bones are small square, oval, and triangular bones. The cluster of carpal bones in the wrist makes it both strong and flexible.

What holds the wrist bones together?

On the extensor aspect, the capsule forms the broad dorsal radiocarpal ligament. On the flexor aspect it forms the palmar radiocarpal ligament. Unlike the elbow, which is held together partly by the interlocking shape of the bones, the wrist is held together entirely by the strength of its ligaments.

What bone stabilizes the carpal bones?

The triquetrum is a bone on the small finger side of the wrist in the first row of wrist bones. This bone adds stability to the wrist, gives the wrist a larger surface to bear weight transmitted from the hand, and makes a joint with other carpal bones including the pisiform.

What features stabilize wrists?
