The Common Palmar Digital Arteries are arteries found in the hand. They are branches of the superficial palmar arch that supply blood to the fingers.

Anatomy

The common palmar digital arteries typically arise as three branches from the convexity of the superficial palmar arch. They run distally along the palmar aspect of the hand, dividing into two proper palmar digital arteries at the level of the metacarpophalangeal joints.

Each common palmar digital artery supplies the adjacent sides of two digits, except for the medial side of the little finger and the lateral side of the thumb, which are supplied by the ulnar artery and the radial artery, respectively.

Clinical Significance

Understanding the anatomy of the common palmar digital arteries is crucial in hand surgery, particularly in procedures involving the replantation of digits and the management of hand trauma.
