The carpus is a complex cluster of eight small bones that make up the wrist joint, connecting the hand to the forearm. These bones are arranged in two rows and are crucial for wrist mobility and stability.

5 Must Know Facts For Your Next Test

  1. The carpus consists of eight bones divided into a proximal row (including the scaphoid, lunate, triquetrum, and pisiform) and a distal row (including the trapezium, trapezoid, capitate, and hamate).
  2. The carpal bones form an arch that creates the carpal tunnel through which nerves and tendons pass.
  3. The scaphoid bone is the most commonly fractured carpal bone due to its location and role in weight transfer from the hand to the forearm.
  4. Ligaments connect the carpal bones to each other as well as to the radius, ulna, and metacarpals, providing stability while allowing for a range of motion.
  5. Osteoarthritis can commonly affect the carpal joints due to wear and tear over time.
