Tuberosity Of The Cuboid Bone, Lateral View

Description

Cuboid tuberosity occupies the plantar-lateral aspect of the cuboid, forming a blunt bony prominence just inferior to the lateral surface in this lateral view. From this fixed perspective, the dorsolateral margin of the cuboid sits superiorly, while the plantar border thickens toward the tuberosity, and the posterior contour leads toward the calcaneal articular surface at the calcaneocuboid joint. The long plantar ligament attachment tracks along the plantar surface adjacent to the tuberosity, and the peroneus (fibularis) longus tendon groove is appreciated on the plantar-lateral region as it courses obliquely toward the medial foot. Small bone. Big landmark. Palpation and radiographic orientation around the lateral midfoot often hinge on this prominence, since pain over the cuboid tuberosity can localize pathology at the calcaneocuboid joint, the peroneus longus tendon sheath, or ligamentous restraints such as the long plantar ligament. In inversion injuries and midfoot sprains, tenderness here raises concern for cuboid fracture, calcaneocuboid subluxation, or traction at the plantar ligament complex, and the lateral view helps separate the tuberosity from dorsal osteophytes that may be mistaken for an avulsion fragment. The single-plane lighting and isolation of the cuboid surface contours make the relief of the tuberosity and the adjacent plantar groove easy to identify when correlating with oblique foot radiographs or CT bone windows. Use this illustration for gross anatomy labs covering the tarsal bones, for podiatry and orthopaedic teaching on lateral column mechanics, and for textbook figures discussing calcaneocuboid joint injury patterns and peroneus longus tendon landmarks. It also fits clinical handouts on lateral midfoot pain localization and surgical planning references for lateral column fixation. Anatomical accuracy verified by SciePro's Medical Advisory Board.
