Posterior Perspective of the Metacarpals

Description

Oriented in a dorsal (posterior) view of the right hand, the metacarpals I to V are highlighted in blue between the distal carpal row proximally and the proximal phalanges distally, forming the bony framework of the metacarpus. Each metacarpal base sits closest to the carpus, the shaft runs distally with a subtle dorsal ridge, and the head expands at the metacarpophalangeal joint. Beige phalanges extend distally in each digit, and portions of the carpal complex remain visible at the wrist. Clear landmarks. Dorsal metacarpal anatomy matters when you need to localize fractures by ray and by segment, since base, shaft, neck, and head injuries behave differently and demand different fixation strategies. Boxer’s fracture classically involves the neck of the fifth metacarpal with apex dorsal angulation, a deformity you read directly from dorsal contours and metacarpophalangeal alignment. The first metacarpal base also deserves attention for Bennett and Rolando fracture patterns at the carpometacarpal joint, where the trapezium-metacarpal relationship drives instability even when the thumb phalanges look intact. Hand surgery and emergency medicine teaching benefit from this color separation when introducing the concept of the five metacarpal rays, metacarpophalangeal joint levels, and dorsal bony landmarks used for palpation and splinting. It also fits cleanly into anatomy lab manuals, orthopedic trauma chapters, and patient-facing fracture education where metacarpals must be distinguished from phalanges and carpal bones at a glance.
