Metatarsus 3D

 

  • Description
    • * The metatarsus consists of 5 metatarsal bones, numbered from the medial to the lateral side.
    • * Each metatarsal is a long bone with a shaft, base, and head.
       
  • 1st metatarsal
    • * It is the shortest, thickest, and stoutest of all metatarsal bones and is adapted for transmission of the body weight
       
  • 2nd metatarsal
    • * It is the longest metatarsal. It has a wedge-shaped base.
       
  • 3rd metatarsal
    • * The lateral side of the base has one facet, placed dorsally, for the fourth metatarsal bone.
    • * The medial side of the base has two facets and plantar for the second metatarsal bone.
       
  • 4th metatarsal
    • * The proximal surface of the base is quadrangular. It articulates with the cuboid bone.
    • * The lateral side of the base has one facet for the fifth metatarsal bone.
    • * The medial side of the base has one facet for the lateral cuneiform and the third metatarsal bone.
       
  • 5th metatarsal
    • * The lateral side of the base has a tuberosity or styloid process projecting backward and laterally.
    • * The medial side of the bone has one facet for the fourth metatarsal bone.
    • * The plantar surface of the bone is grooved by the tendon of the abductor digiti minimi.
