Metatarsophalangeal joints

  • The metatarsophalangeal joints (latin: articulationes metatarsophalangeae) are ovoid or ellipsoid joints between the heads of the metatarsals and the bases of the proximal phalanges.

    The metatarsophalangeal joints are embraced by fibrous capsules that are attached to their articular margins.

    Each joint is reinforced by the collateral, deep transverse metatarsal and plantar ligaments:

    The plantar ligaments (latin: ligg. plantaria) are thick and dense, placed on the plantar surface of the joints between the collateral ligaments.

    The deep transverse metatarsal ligaments (latin: ligg. metatarsale transversum profundum) are flat, narrow bands that connect the heads of all metatarsal bones.

    The collateral ligaments (latin: ligg. collateralia) are string rounded cords which are attached to the dorsal tubercles on the metatarsal heads and the corresponding side of the phalangeal bases.

    The movements permitted by the metatarsophalangeal joints are flexion and extension of the toes, abduction and adduction of the toes.
