Superficial Anatomy of the Dorsum of the Female Hand

Description

Surface landmarks on the dorsum (posterior aspect) of the female hand include the dorsal metacarpophalangeal knuckles and the longitudinal profiles of the metacarpals and proximal, middle, and distal phalanges as they extend distally into the fingers. Along the midline, the extensor digitorum tendons are suggested beneath thin dorsal skin, while the extensor pollicis longus crosses obliquely toward the thumb to border the anatomical snuffbox laterally with the extensor pollicis brevis and abductor pollicis longus. Superficial veins form a dorsal venous network over the metacarpals, draining proximally toward the cephalic vein on the radial side and the basilic vein on the ulnar side. Nails and dorsal digital skin creases mark the distal phalanx and interphalangeal joint levels. Clear landmarks. Clinically, the dorsal hand is a common site for peripheral intravenous cannulation because the dorsal metacarpal veins are accessible and relatively fixed over the underlying fascia. Palpation of the anatomical snuffbox matters in suspected scaphoid fracture, and the same radial-sided region is where de Quervain tenosynovitis localizes pain with thumb motion. Extensor tendon injuries and adhesions are often discussed by dorsal zones across the metacarpals and phalanges, so accurate surface relationships help when teaching tendon repair, boutonniere deformity mechanisms, or postoperative splint positioning. Use this artwork in gross anatomy and surface anatomy teaching modules on the upper limb, as well as in nursing and phlebotomy materials illustrating venous access points and safe cannulation angles on the dorsum of the hand. It also fits orthopedic and hand surgery publications that need a clean reference for dorsal landmarks, tendon trajectories, and the clinical snuffbox on a female model.
