Middle Finger

Description

Dominating the frame is a single extended digit of the manus in a Black adult female, presented with emphasis on the dorsal aspect, including the nail plate and surrounding eponychium and paronychial folds. The distal phalanx sits most distal, followed proximally by the middle and proximal phalanges, with the distal interphalangeal and proximal interphalangeal joints forming clear transverse landmarks. Dorsally, the extensor mechanism lies superficial to the phalanges, while the skin creases and soft tissue contours mark the transition toward the metacarpophalangeal region proximally. One finger is selectively coated in a bright blue material, creating a high-contrast overlay that reads as topical dye or prep on the dorsal surface. Dorsal finger views matter when you need to teach or document nail unit anatomy and extensor tendon relationships, because dorsal swelling, mallet finger (terminal extensor tendon disruption at the distal interphalangeal joint), and PIP joint injuries often present with subtle contour changes rather than obvious palmar findings. The coloration cue also fits common clinical workflows: antiseptic skin preparation, surgical site marking, or dye application used to localize a digit before procedures such as nail bed repair, dorsal laceration exploration, or splinting assessment. Use this asset in hand anatomy teaching for gross anatomy and surface anatomy modules, in dermatology and plastic surgery publications illustrating nail fold landmarks, and in emergency medicine or orthopedics education when explaining dorsal extensor injuries and splint positioning across the interphalangeal joints.
