Which group of carpal bones is referred to as the proximal carpal bones?

The correct answer identifies the proximal carpal bones, which include the scaphoid, lunate, triquetrum, and pisiform. These bones are located closer to the forearm as compared to the distal row of carpal bones.

The scaphoid, which is the largest bone in the proximal row, is crucial for wrist mobility and stability. The lunate is known for its unique moon shape and articulates with the radius. The triquetrum is triangular and has important ligament attachments, while the pisiform is a small, pea-shaped bone that sits atop the triquetrum and is involved in flexor carpi ulnaris tendon attachment and function.

Understanding the anatomy of these carpal bones is essential because they play significant roles in the range of motion and function of the wrist. The distinction between proximal and distal carpal bones is fundamental for diagnosing wrist injuries, planning surgical approaches, and understanding the biomechanics of wrist movements. This knowledge is especially important for orthotic technologists who may be involved in the treatment and management of wrist-related conditions.
