Capitate bone

Capitate Bone

The capitate bone is one of the eight carpal bones that are found in the human hand. It is the largest of the carpal bones, and its name is derived from the Latin caput, meaning "head", due to its distinctive, rounded shape.

Anatomy

The capitate bone is located in the center of the wrist, surrounded by the other seven carpal bones. It articulates with the third metacarpal bone directly and with the second and fourth metacarpal bones indirectly. The capitate bone also articulates with the scaphoid bone and lunate bone proximally, and with the hamate bone on its ulnar side.

Function

The capitate bone plays a crucial role in the movement and flexibility of the wrist and hand. It serves as a pivot point for the rotation of the wrist, and its size and central location allow it to bear a significant portion of the body's weight when the hands are used for support.

Clinical Significance

Injuries to the capitate bone, such as fractures or dislocations, can cause significant pain and loss of function in the hand. These injuries are often associated with falls or other traumatic events. Treatment typically involves immobilization of the wrist and hand, and in severe cases, surgery may be required.
