The Third Metatarsal

Its body, which is prismatic and also triangular, as well as a little rounded inwards at its anterior part, provides a convex superior surface, split into two sections by a prominent line, which offers connection to the second as well as third dorsal interosseous muscles; two lateral surfaces, which represent the very same muscles; and an inferior edge, which is thin, scooped, and grants attachment to the first plantar interosseous muscle. It is a little shorter than the second, however provides almost the exact same kind.

Structure

The Third Metatarsal

The Third Metatarsal

  • Its posterior or tarsal extremity is almost of the exact same type as that of the preceding bone.
  • It provides posteriorly a flat triangular surface, directed inwards, which integrates with the third cuneiform bone; internally, two small surfaces, constant posteriorly, however apart anteriorly by a small depression, and which integrate with the second metatarsal bone; externally, a small concave surface which is gotten in touch with the fourth metatarsal bone, and which is restricted below by impressions of ligaments.
  • The base of this extremity is turned upwards, structurally flat and rough; its top, which is downwards, offers attachment to ligaments.
  • The anterior or phalangeal extremity of this particular bone looks like one of the preceding, and is integrated to the first phalanx of the third toe.

Clinical Significance

Injuries

  1. The four lesser metatarsals supply only one contact point each on the plantar weight-bearing surface.
  2. Considerable ligamentous structures connect each of the bones to their nearby next-door neighbors.
  3. Fractures of the central metatarsals are far more common than separated first metatarsal fractures. Central metatarsal fractures might be separated injuries or part of a more substantial injury pattern.
  4. Indirect twisting systems might lead to a spiral pattern. One should watch out for injury with participation of base of second metatarsal.
  5. Many separated specific central metatarsal fractures can be dealt with closed with hard-soled shoes and escalating weight bearing as endured.
  6. The surgical requirement usually discussed is any fracture showing more than 10 degrees of discrepancy in the dorsal plantar plane or 3 to 4 mm translation in any plane.
  7. Issues of dealing with central metatarsal fractures normally originate from insufficient remediation of plantar anatomy.
