'''Pisiform bone''' is a small knobbly, pea-shaped bone found in the human hand. It is considered a [[sesamoid bone]] and is situated where the palm of the hand meets the outer edge of the wrist. The pisiform bone is part of the [[ulnar bone]] complex and is located in the proximal row of the [[carpus]]. It is the bone that is closest to the surface of the palm and is easily palpable.

==Structure==
The pisiform bone is a small, pea-shaped bone that is located in the [[wrist]]. It is situated on the anterior side of the carpal bone, in the proximal row of the carpus. The bone is embedded within the tendon of the [[flexor carpi ulnaris muscle]], which is one of the muscles that control the movement of the wrist and hand.

==Function==
The primary function of the pisiform bone is to support the [[ulnar artery]], which supplies blood to the hand. It also serves as a support for the flexor carpi ulnaris muscle, providing a surface for the muscle to attach to. This muscle is responsible for flexing the wrist and assisting in the adduction of the hand.

==Clinical significance==
Injuries to the pisiform bone are relatively rare, but can occur as a result of direct trauma to the hand or wrist. Fractures of the pisiform bone can cause pain, swelling, and difficulty moving the wrist and hand. In some cases, the pisiform bone may need to be surgically removed, a procedure known as a [[pisiformectomy]].
