A Lateral View Of The Metatarsal Base

Description

Rotating through a lateral perspective of the foot, the animation centers on the proximal base of a metatarsal and its wedge-like geometry, with the dorsal and plantar margins reading clearly as the bone turns. Articular facets at the metatarsal base appear as smooth, gently convex and concave surfaces that transition into adjacent nonarticular cortex, while the shaft extends distally in line with the longitudinal arch. As the sequence advances, the lateral profile helps separate the base from the neck and head, so you can track how the pedal skeleton stacks from proximal to distal. That proximal contour matters in midfoot mechanics and injury patterns. The metatarsal bases form the tarsometatarsal (Lisfranc) complex with the cuneiforms and cuboid, where small changes in alignment can signal a Lisfranc sprain or fracture-dislocation, often missed on nonweightbearing radiographs. Motion makes the key teaching point: as the bone rotates, the viewer can appreciate how wedge shape and facet orientation contribute to stability and how a subtle step-off at the base would alter joint congruity. Use this animation in gross anatomy and lower limb musculoskeletal courses to reinforce metatarsal regional anatomy (base, shaft, head) and in radiology or orthopaedic teaching files when correlating oblique and lateral foot projections with midfoot trauma. It also fits well in publisher content on foot biomechanics, tarsometatarsal arthrodesis planning, and clinical overviews of Lisfranc injuries.
