A Medial View Of The Base Of The Metatarsal Bone

Description

Rotating through a medial perspective, the animation focuses on the proximal base of a metatarsal at the midfoot, with the shaft extending distally toward the metatarsal head and toes. The medial contour and plantar aspect of the base are emphasized as the camera angle shifts, clarifying how the proximal articular surface seats against the tarsus while the dorsum and sole define the longitudinal arch. Subtle changes in obliquity help separate the medial border from the dorsal surface and the plantar tuberosity region. Orientation is the point. Clinically, the metatarsal base is a common site of diagnostic confusion on radiographs and CT because small avulsion fragments and articular step-offs hide along the medial and plantar margins. This animated sequencing helps you track the transition from non-articular cortical bone to the proximal joint surface, a distinction that matters when assessing tarsometatarsal (Lisfranc) alignment, occult base fractures, and post-traumatic midfoot instability. It also supports teaching where the metatarsals contribute to the medial longitudinal arch through their proximal geometry and ligamentous attachments, which are easier to conceptualize when the bone is seen turning in space. Use it in gross anatomy labs and lower-limb modules to teach bony landmarks of the pedal skeleton, and in orthopaedic and podiatry teaching files to accompany cases of metatarsal base fractures and midfoot sprain patterns. Publishers can pair the clip with atlas plates or radiology primers to reinforce medial versus dorsal versus plantar orientation of the metatarsals.
