Extensor Hallucis Brevis Muscle, Dorsal View

Description

Arising from the superolateral dorsum of the calcaneus, the extensor hallucis brevis appears as a small, compact muscle belly on the dorsolateral foot, deep to the extensor digitorum brevis and lateral to the long extensor tendons. Its tendon courses anteriorly and medially toward the hallux, lying inferior to the extensor hallucis longus tendon as it approaches the first metatarsophalangeal region. The muscle sits superficial to the dorsal surface of the calcaneus and tarsal bones, with the lateral malleolar region positioned proximolaterally and the first ray oriented distomedially. Clear dorsal topography matters here. A dorsal view of extensor hallucis brevis is the cleanest way to teach intrinsic extensor anatomy and tendon layering at the first ray, where small differences in tendon position can confuse learners. Pain and swelling on the dorsum of the foot are common after forced plantarflexion or repetitive overuse, and focal tenderness over the dorsolateral midfoot can reflect extensor hallucis brevis strain or tenosynovitis, often discussed alongside extensor hallucis longus tendon irritation and dorsal midfoot ganglion cysts. For surgeons and sports clinicians, this regional anatomy also frames the course of the deep fibular (peroneal) nerve and dorsalis pedis artery as they traverse the dorsum toward the first intermetatarsal space, a practical consideration for dorsal approaches and injection planning. Use this asset in lower limb anatomy teaching for medical and podiatry curricula, and in orthopaedic, sports medicine, and physiotherapy materials explaining hallux extension mechanics and dorsal foot pain differentials. It also supports textbook figures and patient education graphics that need a precise depiction of intrinsic foot extensor musculature in a male adult.
