Arteries of the Hand, Posterior View

Description

Seen from the dorsum of a male hand, the superficial and deep palmar supply is translated into its dorsal counterpart, with the dorsal carpal arch feeding dorsal metacarpal arteries that run distally in the intermetacarpal spaces. Radial contribution is suggested laterally at the anatomical snuffbox region and across the bases of the metacarpals, while ulnar inflow approaches medially toward the dorsal carpal network. Distally, dorsal digital arteries track along the sides of the fingers, accompanied by a conspicuous dorsal venous network in blue that converges proximally toward the dorsal metacarpal veins. Clear territory mapping. Dorsal hand vascular anatomy matters because it is where clinicians frequently encounter vessels directly in the operative field and during vascular access. Lacerations over the metacarpals often injure dorsal metacarpal arteries or their accompanying veins, and flap planning for dorsal metacarpal artery perforator flaps depends on understanding the intermetacarpal course and distal anastomoses with palmar digital branches. This posterior view also supports interpretation of Allen testing and angiographic patterns by reminding you that dorsal and palmar circulations communicate through consistent distal connections. Use this illustration in gross anatomy and hand surgery teaching to relate surface landmarks, the anatomical snuffbox, and the dorsal venous network to the deeper arterial pattern, or in medical device and wound-care publications addressing dorsal hand trauma, cannulation, and reconstructive options. It also suits radiology and vascular modules as a labeled companion to Doppler ultrasound and angiography of the distal upper limb. Anatomical accuracy verified by SciePro's Medical Advisory Board.
