Dorsal Aspect of the Great Toe

Description

Dorsally, the adult male hallux is presented from the nail plate to the level of the first metatarsophalangeal joint, with the broad nail bed and surrounding eponychium and lateral nail folds framing the distal phalanx. Proximally, the interphalangeal joint lies between the distal and proximal phalanges, and the metatarsophalangeal joint forms the transition to the first metatarsal head. Medial and lateral contours of the toe pad and dorsum help orient the first digit relative to the adjacent second toe position, while the extensor hallucis longus tendon course can be inferred along the dorsal midline as it approaches its insertion on the distal phalanx. A clean dorsal silhouette. This dorsal perspective matters because many hallux problems declare themselves at the nail unit and dorsal joints before plantar symptoms appear. Ingrown toenail (onychocryptosis) and paronychia track along the lateral nail fold, while subungual hematoma and onychomycosis alter the nail plate and bed in ways that are best taught from the dorsum. At the metatarsophalangeal joint, dorsal osteophytes and capsular thickening in hallux rigidus limit dorsiflexion and become relevant for cheilectomy planning, where surgeons work from the dorsal approach and need clear surface landmarks. Use this view for gross anatomy and podiatry teaching on the first digit, for dermatology and primary care references on nail pathology, and for orthopedic or sports medicine materials discussing hallux rigidus, turf toe mechanics, and postoperative incision placement over the dorsum of the foot.
