Common Palmar Digital Artery

The Common Palmar Digital arteries arise from the superficial palmar arterial arch and proceed distally on the second to fourth lumbricals. Palmar digital arteries supply metacarpophalangeal and interphalangeal joints and nutrient rami to the phalanges. They are the main digital supply.

Ligature of one forearm artery may be ineffective in wounds of the palmar arches; simultaneous tying of both arteries proximal to the carpus may also fail, because of interosseo-carpal anastomoses. If local pressure fails, the brachial artery may be compressed as a temporary expedient.
