The Base Of The Toe's Proximal Phalanx From A Lateral View

Description

Oriented in a lateral view of the foot, the animation isolates the base of a toe’s proximal phalanx, the expanded proximal metaphyseal region immediately distal to the metatarsophalangeal (MTP) joint. The proximal articular surface for the corresponding metatarsal head comes into profile, with the dorsal aspect positioned superiorly and the plantar surface inferiorly, clarifying how the wider base transitions into the narrower shaft distally. As the sequence progresses, subtle rotation and reframing keep the lateral contour, cortical margin, and periarticular geometry in view while maintaining consistent anatomical position. Understanding the base of the proximal phalanx matters when you are teaching or interpreting MTP joint mechanics and common injury patterns at the forefoot. Capsuloligamentous structures (collateral ligaments and plantar plate) attach around this periarticular rim, so fractures, avulsion fragments, and osteophytes at the phalangeal base can contribute to MTP instability, plantar plate insufficiency, and painful dorsal impingement. Motion adds clarity: the animation makes it easier to appreciate how small changes in contour at the articular margin can alter joint congruence and toe alignment, a point that often gets lost in a single still. Use this asset in podiatry and orthopedic anatomy teaching, forefoot biomechanics lectures, and radiology correlation when discussing oblique foot radiographs or CT reconstructions of phalangeal base fractures and MTP degenerative change. It also suits medical publishing layouts that need a clean lateral bony landmark reference for toe splinting, reduction technique overviews, or surgical planning diagrams.
