Body Of The Metatarsal Bone, Medial View

Description

Metatarsal shaft anatomy is presented in medial view, emphasizing the body as the elongated diaphyseal segment between the proximal base and distal head. The medial cortical surface runs longitudinally from the tarsometatarsal end toward the metatarsophalangeal end, with the dorsal margin positioned superiorly and the plantar margin inferiorly. Proximally, the body expands into the base for articulation at the tarsometatarsal joint (with a cuneiform or the cuboid depending on which metatarsal is referenced), while distally it narrows toward the neck and head that articulate with the proximal phalanx. A subtle plantar contour and the sharpness of the medial border help orient the bone in standard anatomical position. Metatarsal body morphology matters in both injury patterns and operative planning because the diaphysis is the common site for stress reactions and stress fractures in runners, recruits, and patients with osteopenia, where cortical thickening, callus formation, and malalignment change load transmission through the forefoot. Alignment errors at the shaft influence metatarsalgia and transfer lesions, and the medial profile is a practical reference when discussing sagittal plane deformity, dorsal angulation, or plantarflexion of a ray after trauma or osteotomy. Surface cues along the shaft also support teaching of muscular and fascial relationships, including interosseous attachments along the sides and the plantar soft tissue envelope that cushions the metatarsal heads. Use this illustration in gross anatomy and osteology labs, podiatry and orthopedic teaching files, and medical publishing layouts covering the forefoot skeleton, tarsometatarsal alignment, and metatarsal fracture classification and fixation concepts. Precise for slide decks on gait biomechanics, stress fracture risk, and preoperative counseling images for metatarsal osteotomy procedures.
