Male Fifth or Little Finger, Posterior View

Description

From a posterior (dorsal) perspective, the male fifth digit is shown from the level of the metacarpophalangeal region through the middle and distal phalanges to the fingertip. Dorsal skin creases and surface texture are apparent over the proximal and distal interphalangeal joints, with the nail plate and nail folds positioned dorsally at the distal phalanx. The digit lies ulnar to the ring finger in anatomical position, and its dorsal contour reflects the underlying phalangeal shafts and joint prominences. Dorsal little-finger anatomy matters when you need reliable surface landmarks for extensor mechanism injury and for documenting trauma patterns. Mallet finger involves disruption of the terminal extensor tendon at the distal interphalangeal joint and is assessed from the dorsal aspect where extension lag and soft-tissue swelling are most evident. The same dorsal view is also used to teach collateral ligament evaluation at the proximal interphalangeal joint, where swelling and ecchymosis can obscure subtle joint line asymmetry. Use this image for gross anatomy and surface anatomy teaching on hand digits, for emergency medicine and orthopedics materials illustrating dorsal finger trauma assessment, or for plastic surgery and hand therapy references discussing splinting positions and skin care around the nail complex.
