Metatarsal Showing Its Head, Lateral View

Description

Metatarsal head anatomy is presented from a lateral (fibular) perspective, emphasizing the convex articular surface that faces distally to meet the base of the proximal phalanx at the metatarsophalangeal (MTP) joint. Proximally, the narrowed metatarsal neck transitions into the diaphysis, while the head expands plantarly and dorsally into a rounded contour with subtle asymmetry between its dorsal margin and the more weight-bearing plantar aspect. Along the lateral side of the head, the nonarticular cortical rim and the area where the lateral collateral ligament complex attaches sit just proximal to the articular margin, a small but teachable relationship when orienting the toe in anatomical position. Bone landmarks read cleanly. This lateral profile matters any time you need to explain how forefoot load transfers through the MTP joint, because the metatarsal head is the bony interface implicated in metatarsalgia, MTP synovitis, and plantar plate insufficiency, conditions often discussed in the setting of a long or plantarflexed metatarsal. Orthopaedic and podiatric teaching frequently hinges on distinguishing the dorsal articular contour (relevant to dorsal osteophytes and hallux rigidus when the first ray is involved) from the plantar contour that relates to callus patterns and sesamoid mechanics. The fixed viewpoint also supports surgical communication: when describing a distal metatarsal osteotomy or cheilectomy corridor, lateral cortical reference points and the head-neck junction provide reliable orientation without needing multiple projections. Use this illustration in gross anatomy and kinesiology modules on the foot, in radiology teaching files when correlating oblique radiographs of the MTP joint with palpable landmarks, or in operative manuals discussing distal metatarsal procedures and common sources of postoperative transfer lesions.
