metatarsal

Examples of metatarsal in the following topics:

• Tarsals, Metatarsals, and Phalanges (The Foot)

  • The human ankle and foot bones include tarsals (ankle), metatarsals (middle bones), and phalanges (toes).
  • Each metatarsal consists of a head, shaft, and base.
  • The proximal base articulates with the cuboid bones, and distally with the proximal phalanges, and each metatarsal also articulates laterally with adjacent metatarsals.
  • The interossei of the foot originate from the shafts of the metatarsals.
  • The digits are named in a similar fashion to the metatarsals, medial to lateral from the big toe.

• Metatarsal Fracture

  • Fractures commonly include the 5th metatarsal (a Jones fracture) or fractures of the distal third of one of the metatarsal (March fracture).
  • A Jones fracture is a fracture of the diaphysis of the fifth metatarsal of the foot .
  • The fifth metatarsal is at the base of the small toe.
  • In ballet dancers, fracture mostly occurs at the base of the second metatarsal.
  • Analyze why a Jones fracture of the 5th metatarsal often does not heal and the causes of a March fracture of the metatarsal bone

• Muscles that Cause Movement at the Foot

  • Dorsal Interossei - There are four dorsal interossei located between the metatarsals.
  • Each arises from two metatarsals.
  • Attachments - Originates from the sides of metatarsals one to five (big toe to little toe).
  • Each is connected with one metatarsal bone.
  • Attachments - Originates from the medial side of metatarsals three to five.

• Arches of the Feet

  • The arches of the foot are formed by the tarsal and metatarsal bones; they dissipate impact forces and store energy for the subsequent step.
  • The arches of the foot are formed by the tarsal and metatarsal bones.
  • It is made by the calcaneus, the talus, the navicular, the three cuneiforms, and the first, second, and third metatarsals.
  • Its two extremities or piers, on which it rests in standing, are the tuberosity on the plantar surface of the calcaneus posteriorly, and the heads of the first, second, and third metatarsal bones anteriorly.
  • It is composed of the calcaneus, the cuboid, and the fourth and fifth metatarsals.

• The Appendicular Skeleton

  • Feet and ankles (52 bones) - Left and right tarsals (14) (ankle), metatarsals (10), proximal phalanges (10), intermediate phalanges (8) and distal phalanges (10)
  • These consist of the femur, patella, tibia, fibula, tarsal bones, metatarsal bones, and phalanges.
  • The bones of the foot are divided into three groups, the tarsal bones, metatarsal bones, and phalanges of the foot. 

• Overview of the Appendicular Skeleton

  • Feet and ankle (52 bones) - The feet and ankle consist of the tarsals (14 bones in the ankle), Metatarsals (10 bones), Proximal phalanges (10 bones), Middle phalanges (eight bones), and Distal phalanges (10 bones).

• Congenital Defects

  • Examples of minor anomalies can include curvature of the 5th finger (clinodactyly), a third nipple, tiny indentations of the skin near the ears (preauricular pits), shortness of the 4th metacarpal or metatarsal bones, or dimples over the lower spine (sacral dimples).

• Flatfoot and Clawfoot

  • The range of complaints reported from people with pes cavus include metatarsalgia, pain under the first metatarsal, plantar fasciitis, painful callosities, ankle arthritis, and Achilles tendonitis.

• Gross Anatomy

  • Other examples include the small bones f the metatarsals and the pisiform bones of the carpus.
