Body Of A Metatarsal, Lateral View

Description

Metatarsal diaphysis (body) dominates the frame in lateral profile, with the proximal base positioned posteriorly and the distal head oriented anteriorly toward the metatarsophalangeal region. A gentle longitudinal bow is visible, with the cortex arcing toward the plantar surface and the dorsal aspect forming the opposing concavity. The shaft tapers slightly as it approaches the neck, while the plantar contour reads as a continuous load-bearing curve rather than a straight segment. Fine cortical margins and the transition zones toward base and head remain distinct from this fixed lateral viewpoint. That plantar-directed curvature matters when you are teaching or planning around forefoot biomechanics and injury patterns, because bending moments concentrate at the metatarsal neck and mid-diaphysis during toe-off and repetitive impact. Stress fractures of the second and third metatarsals (classic march fractures) and dorsal cortical reactions are often discussed alongside the longitudinal arch and the lever arm created by the metatarsal parabola. Lateral presentation also helps clarify how plantarflexed metatarsals can contribute to metatarsalgia and callus formation under the corresponding metatarsal head by increasing plantar pressure. Bone shape drives symptoms. The lighting and edge definition support clean separation of dorsal versus plantar cortices, which is useful for labeling and for correlating with lateral foot radiographs. Orthopaedic and podiatry educators will find this illustration well suited for lower-limb osteology labs, foot and ankle exam guides, and textbook figures addressing metatarsal anatomy, fracture patterns, and operative landmarks for intramedullary fixation or plate positioning. It also integrates smoothly into lectures on gait mechanics and the medial longitudinal arch when paired with tarsal and phalangeal plates.
