Interphalangeal joints of foot

The interphalangeal joints of the foot (also interphalangeal articulations, latin: articulationes interphalangeae pedis) are articulations between the phalanges of the toes. The interphalangeal joints belong to hinge joints.

Within each interphalangeal joint articulates:

  • base of the phalanx
  • head of the phalanx.

Each interphalangeal joint has an articular capsule, and it is reinforced by two collateral ligaments (ligg. collateralia) on each side, and the plantar ligaments (ligg. plantaria).

The movements permitted by the interphalangeal joints, although limited, are flexion and extension of the medial and distal phalanges.
