A Lateral View Of The Metatarsal Showing Its Head

Description

Rotating in a lateral perspective, the animation isolates a single metatarsal and settles on the distal head (caput ossis metatarsalis), the convex articular surface that faces distally to meet the base of the proximal phalanx at the metatarsophalangeal (MTP) joint. The shaft (corpus) extends proximally and slightly plantarward relative to the head, with the dorsal surface oriented superiorly and the plantar surface inferiorly. As the sequence turns, the transition from nonarticular cortical bone to the smooth hyaline cartilage bearing area becomes obvious. Subtle changes in contour on the lateral aspect are emphasized as the bone moves. This specific angle matters when you are teaching or planning around MTP joint mechanics and the load paths through the forefoot during toe-off. Hallux valgus discussions often focus on medial deviation of the first metatarsal and sesamoid maltracking, but the lateral profile of the metatarsal head helps explain why joint congruency and dorsiflexion at the MTP can be lost with osteophytes, chondral wear, or altered metatarsal parabola. Motion helps. Seeing the head’s curvature from lateral to dorsolateral clarifies why small changes in alignment can shift contact pressures and drive metatarsalgia. Use this clip in lower-limb osteology labs, podiatry and orthopaedic teaching on forefoot biomechanics, or as an insert for clinical texts describing MTP osteoarthritis, bunion deformity, and surgical concepts such as metatarsal osteotomy planning and joint-sparing procedures. It also fits radiology education when correlating oblique foot radiographs with true lateral bony contours. Anatomical accuracy verified by SciePro's Medical Advisory Board.
