Body Of The Distal Phalanx, Superior View

Description

Distal phalanx of a toe is presented in superior (dorsal) view with the osseous body centered in the frame. The shaft narrows from the proximal base toward the distal tuft, and its midportion shows a gentle inward curvature along the long axis, creating a subtle concavity along the dorsal contour. Proximally, the expanded base sits superior to the distal interphalangeal (DIP) joint surface, while distally the broadened apical region indicates the terminal tuft that supports the pulp and nail complex. Bone landmarks read cleanly. Dorsal morphology of the distal phalanx matters when you need to correlate surface anatomy with radiographs and with the mechanics of the extensor apparatus at the DIP joint, where small avulsion fragments can accompany mallet toe injuries. Crush trauma to the hallux or lesser toes often produces comminuted tuft fractures, and the relationship between a curved shaft and the distal tuft helps explain why fracture lines may propagate obliquely rather than purely transverse. Fine bony contour is also relevant in chronic infection, because distal phalanx osteomyelitis (often following nail-bed trauma or diabetic ulceration) produces cortical irregularity and focal lysis that clinicians compare against expected dorsal smoothness. Podiatry and orthopaedic teaching files can pair this illustration with AP and oblique foot radiographs to reinforce identification of the distal phalanx body versus tuft and base, and to anchor discussions of DIP joint alignment, nail-bed injury, and distal toe fractures. Medical publishers will also find it well suited for atlas plates on the phalanges of the foot and for exam items targeting distal phalanx landmarks in a superior view.
