Carpalia, also known as carpal bones, refer to a group of eight small bones located in the wrist region of the human body. These bones are situated between the forearm bones, known as the radius and ulna, and the bones of the hand. The term "carpalia" is derived from the Greek word "karpos," meaning wrist.
These bones form the anatomical structure of the wrist joint, providing stability, flexibility, and support for movements of the hand and fingers. The eight carpalia bones can be divided into two rows: the proximal row and the distal row. The proximal row consists of the scaphoid, lunate, triquetrum, and pisiform bones, while the distal row comprises the trapezium, trapezoid, capitate, and hamate bones.
The carpalia bones serve as attachments for various ligaments and tendons, enabling a wide range of wrist movements, including flexion, extension, abduction, adduction, and rotational movements. Their intricate arrangement and coordination also contribute to the proper functioning of the carpal tunnel, a narrow passageway in the wrist that allows the passage of nerves and tendons.
Injuries or disorders of the carpalia bones can lead to various conditions, such as carpal tunnel syndrome, wrist fractures, or arthritis. Medical professionals, such as orthopedic surgeons and radiologists, often utilize imaging techniques such as X-rays, CT scans, or MRI scans to assess and diagnose any abnormalities or injuries in the carpalia bones.
