Metatarsophalangeal joints

The metatarsophalangeal joints (MTP joints), also informally known as toe knuckles, are the joints between the metatarsal bones of the foot and the proximal bones (proximal phalanges) of the toes. They are condyloid joints, meaning that an elliptical or rounded surface (of the metatarsal bones) comes close to a shallow cavity (of the proximal phalanges).

Metatarsophalangeal joints
The MTP, IP, PIP, and DIP joints of the foot:
  • MetaTarsoPhalangeal, at the ball of the foot
  • Interphalangeal joints of the foot:
    • InterPhalangeal (big toe only has one joint)
    • Proximal InterPhalangeal
    • Distal InterPhalangeal
