Metatarsal Anatomy

Proximally tarsometatarsal joints between the metatarsal bases and the tarsal bones. The metatarsal bones are connected to the bones of the toe or phalanges at the knuckle of the toe or metatarsophalangeal joint.

It has a broad base expanded laterally to form the tuberosity a narrow shaft and a fairly small head.

Metatarsal anatomy. The metatarsals are the bones of the foot present between the heel tarsus of the foot and the toes. Metatarsalgia is a common overuse injury. The base articulates with the cuboid and with the fourth metatarsal.

2nd 5th metatarsal have distal intermetatarsal ligaments that maintain length and alignment with isolated fractures implicated in formation of interdigital mortons neuromas multiple metatarsal fractures lose the stability of intermetatarsal ligaments leading to increased displacement. The first second third fourth and fifth metatarsal often depicted with roman numerals. The second plantar interossei muscle originates from the medial side of the base and shaft.

They have three or four articulations. These are a group of five long cylindrical bones that are collectively called metatarsus. The metatarsal bones run from the tarsus forming the tarsometatarsal joints to the base of proximal phalanges forming the metatarsophalangeal joints.

Lacking individual names the metatarsal bones are numbered from the medial side the side of the great toe. The anatomy of these joints and their ligaments has not been described in detail. Lateral shaft 3rd dorsal interosseus.

The muscle attachments of the third metatarsal are the following. These bones do not have individual names rather these are numbered from inside to outside. Each metatarsal has a similar structure.

The metatarsal bones or metatarsus are a group of five long bones in the foot located between the tarsal bones of the hind and mid foot and the phalanges of the toes. It is often thought of as a symptom of other conditions rather than as a specific disease. Metatarsals are convex in shape arch upward are long bones and give the foot its arch.

The horizontal head of the adductor hallucis also originates from the lateral side. Medial shaft 2nd dorsal interosseus and 1st plantar interosseus. The fifth metatarsal forms the mobile lateral foot border.

They work with connective tissues ligaments and tendons to provide movement in the foot. Fourth metatarsal bone the third and fourth dorsal interossei muscles originates from fourth metatarsal bone. They are convex dorsally and consist of a head neck shaft and base distal to proximal.

The term describes pain and inflammation in the ball of the foot.
