Fifth Metatarsal's Tuberosity, Superior View

Description

Tuberosity of the fifth metatarsal dominates the lateral margin of the forefoot in this superior (dorsal) view, projecting proximally from the expanded base just distal to the cuboid articulation. From this fixed perspective, the metatarsal shaft extends distally and medially toward the head, while the dorsal surface contours lead the eye from the broad base into the narrower diaphysis. Lateral prominence is unmistakable. Adjacent dorsal landmarks, including the metaphyseal flare and the proximal articular region for the fourth metatarsal, help orient the viewer to the outer column of the foot. Clinically, the tuberosity is the attachment site for the peroneus brevis tendon and part of the lateral band of the plantar aponeurosis, which explains the characteristic avulsion pattern seen with inversion injuries at the base of the fifth metatarsal. A nearby transverse zone at the metaphyseal-diaphyseal junction relates to the classic Jones fracture, while more distal stress fractures occur in athletes and military recruits where bending forces concentrate along the lateral ray. Superior viewing highlights the dorsal contour and border definition that clinicians palpate and that surgeons reference when planning screw fixation trajectories, while keeping the relationship between the base, shaft, and lateral prominence unambiguous in a single frame. Teaching modules on foot and ankle anatomy often need a focused bony landmark image to pair with surface anatomy, radiographs, and operative technique discussions of fifth metatarsal base injuries. This illustration also fits well in orthopedic texts, podiatry lectures, and patient-education materials describing lateral foot pain localized to the styloid region after ankle sprain.
