Posterior Portion of the Heel

Description

Shown in medial profile, the posterior calcaneal region is emphasized with a blue overlay centered on the calcaneal tuberosity and the adjacent soft-tissue envelope of the heel pad. The Achilles tendon footprint lies posterosuperior on the calcaneus, while the plantar surface transitions inferiorly toward the medial process of the calcaneal tubercle where the plantar aponeurosis arises. Medial to the calcaneus, the contour of the hindfoot suggests the course of the tarsal tunnel structures (posterior tibial artery and nerve with their branches) as they pass posterior to the medial malleolus toward the plantar foot. Skin tone and surface landmarks are rendered for realistic external correlation. Medial and posterior heel anatomy matters because small shifts in load distribution translate into predictable pain generators: insertional Achilles tendinopathy at the posterosuperior calcaneus, retrocalcaneal bursitis deep to the tendon, and plantar fasciitis at the medial calcaneal tubercle. Pressure concentrates under the calcaneal fat pad during initial contact in gait, and shear at this interface drives both blistering and diabetic foot ulcer risk when sensation is impaired. Accurate external mapping of these landmarks also supports operative planning for posteromedial approaches that avoid the posterior tibial neurovascular bundle. Use this illustration in podiatry and orthopedic teaching for hindfoot surface anatomy, in physical therapy materials addressing Achilles loading programs, or in wound-care protocols where offloading and heel protectors are selected based on contact mechanics. It also fits orthotic design and footwear documentation when explaining medial heel posting, heel cup geometry, and pressure-point mitigation for darker skin tones in patient education.
