The Tuberosity Of The Fifth Metatarsal Bone From A Lateral View

Description

Along the lateral border of the human foot, the animation isolates the fifth metatarsal and settles into a true lateral view of its proximal base. The tuberosity (tuberositas ossis metatarsalis quinti) appears as a roughened posterolateral prominence, immediately distal to the cuboid articulation and proximal to the shaft that runs anteromedially toward the little toe. As the sequence progresses, subtle rotation and tightening focus bring the insertional area for the fibularis brevis tendon into relief, while the plantar aspect of the base and adjacent cortical contours remain readable for orientation. Clinical relevance centers on lateral midfoot pain and fractures at the proximal fifth metatarsal, where precise localization changes management. Avulsion fractures of the tuberosity at the fibularis brevis insertion are commonly conflated with Jones fractures at the metaphyseal diaphyseal junction, yet they differ in vascular supply, nonunion risk, and weight-bearing recommendations. Motion helps here: the animated turn clarifies where the tuberosity ends and the proximal shaft begins, and it makes the joint line with the cuboid and the plantar lateral corner easier to distinguish than in a single static frame. Small landmark. Big consequences. Use this clip in gross anatomy and lower limb musculoskeletal modules when teaching the lateral column of the foot, tendon insertions, and bony surface anatomy. It also fits radiology and sports medicine content that pairs clinical examination with oblique foot radiographs or CT reconstructions, and orthopaedic teaching on fracture classification and operative planning around the fifth metatarsal base.
