Radialis indicis artery

Last revised by Leon Chau on 22 Jan 2022

The radialis indicis artery is a branch of the radial artery in the hand that supplies the radial aspect of the index finger (2nd digit). It arises from the radial artery in the palm just after the origin of the princeps pollicis artery. The artery courses distally along the radial (lateral) palmar aspect of 2nd metacarpal and between the 1st dorsal interossei and adductor pollicis muscles.

Variant anatomy

The radialis indicis artery may arise directly from the princeps pollicis artery.
