Extensor Hallucis Brevis, Dorsal View

Description

Seen from the dorsum of a male foot, the extensor hallucis brevis is presented as a short intrinsic muscle belly on the superolateral aspect of the midfoot, with its slender tendon running distally toward the hallux. Deep bony landmarks of the tarsus and metatarsus are visible beneath the soft tissues, including the talus and calcaneus proximally, the navicular and cuboid in the midfoot, and the cuneiforms articulating with the metatarsals. The tendon courses anterior to the tarsometatarsal region and approaches the proximal phalanx of the great toe, where it contributes to extension at the first metatarsophalangeal joint. Joint surfaces are tinted to indicate the synovial articulations across the tarsal, tarsometatarsal, and metatarsophalangeal levels. Dorsal foot anatomy can look deceptively spare, so isolating extensor hallucis brevis helps clarify how hallux extension is shared between extensor hallucis longus and the intrinsic extensor mechanism. This is a surgical neighborhood. Dorsal approaches to the first ray and midfoot, as well as arthroscopy portals around the talonavicular and tarsometatarsal joints, require clean mental mapping of superficial tendons relative to bony ridges to avoid iatrogenic injury and postoperative adhesions that limit great toe dorsiflexion. Ideal for gross anatomy lab manuals, orthopaedic and podiatry teaching slides, and textbook figures on intrinsic foot muscles, this plate also supports patient education graphics for dorsal midfoot procedures and rehabilitation focused on hallux extension mechanics. A strong choice for annotating the first metatarsophalangeal joint and dorsal tendon landmarks. Anatomical accuracy verified by SciePro's Medical Advisory Board.
