Capitate: The Largest Carpal Bone, Crucial to Wrist Function
The capitate, the largest of the carpal bones, plays a crucial role in the wrist and hand. Located centrally, it connects with several other bones, providing stability and facilitating movement.
The capitate, as described by 19th-century anatomist Guillaume Duchenne, is convex on its superior and inferior surfaces. This shape allows it to articulate with the concave surfaces of the scaphoid and lunate, two other carpal bones. It lies between the trapezoid and hamate, further securing its position.
Despite its central location and robust connections, fractures to the capitate are uncommon. Its protected position reduces the risk of injury. It attaches to various carpal bones, including the trapezoid, trapezoid, and triquetrum, and touches several metacarpal bones, demonstrating its integral role in wrist function.
The capitate, the largest carpal bone, is a vital component of the wrist. Its unique shape, central location, and numerous connections provide stability and enable movement. Despite its importance, fractures to the capitate are rare due to its protected position.
