Calcaneal Tuberosity, Medial View

Description

Calcaneal tuberosity anatomy is presented from the medial aspect, bringing the posterior plantar heel into profile while keeping the superior articular surface in view. Along the superior surface, the posterior (superior) talar facet sits superior and slightly anterior to the middle talar facet, and the intervening ridges are visible as raised margins that help separate subtalar contact areas. Posteriorly and inferiorly, the medial process of the calcaneal tuberosity forms the prominent plantar heel contour, with the expected attachment region for the plantar aponeurosis located on its inferior surface and the Achilles tendon insertion positioned more superiorly on the posterior calcaneus. Bony relief is the message. These landmarks matter any time heel pain or hindfoot alignment is the clinical question. The medial tubercle of the calcaneal tuberosity is the classic enthesis implicated in plantar fasciitis and plantar heel spur formation, and it lies close to the course of the first branch of the lateral plantar nerve (Baxter nerve), a frequent source of neuropathic heel pain. The spacing and curvature of the posterior and middle talar facets also orient the viewer to subtalar joint congruity, a point that becomes practical when explaining calcaneal fractures involving the posterior facet, subtalar arthritis, or the mechanical rationale behind medializing calcaneal osteotomy for adult-acquired flatfoot. Use this illustration in gross anatomy teaching of the tarsal bones, in orthopedic and podiatry lecture decks covering plantar heel pain and subtalar joint biomechanics, or in operative planning figures that need a consistent medial bony landmark reference for incisions, osteotomy sites, and fixation trajectories.
