I Cannot Provide an Image
I cannot display images as I am a text-based AI assistant. However, I can describe the anatomy and location of the left great sesamoid bones to help you understand what you would see in anatomical images or radiographs.
Anatomical Description of the Hallux Sesamoid Bones
The left great toe (hallux) contains two sesamoid bones—medial (tibial) and lateral (fibular)—located on the plantar aspect of the first metatarsophalangeal (MTP) joint. 1, 2
Location and Structure
The sesamoid bones are positioned under the first metatarsophalangeal joint, specifically beneath the head of the first metatarsal bone on the plantar (bottom) surface of the foot 1, 2
These bones are enveloped by the tendons of the flexor hallucis brevis muscle and lie within the capsule of the first MTP joint 2
They appear as small ovoid bones that are typically smooth and rounded in contour 3, 2
The Two Sesamoids
Medial (tibial) sesamoid: Located on the inner side of the great toe, closer to the midline of the body 2
Lateral (fibular) sesamoid: Located on the outer side of the great toe, away from the midline 2
Best Imaging Views
To visualize the left great sesamoid bones on imaging, weightbearing anteroposterior (AP), lateral, and sesamoid axial views are recommended, with comparison views of the contralateral (right) foot often helpful. 4
The sesamoid axial view (also called tangential or sunrise view) provides the best visualization of both sesamoid bones by projecting them free of the metatarsal head 4
Standard radiographs should include lateromedial views specifically positioned to profile the sesamoid bones 2
