- Source: Metatarsophalangeal joints
The metatarsophalangeal joints (MTP joints) are the joints between the metatarsal bones of the foot and the proximal bones (proximal phalanges) of the toes. They are analogous to the knuckles of the hand, and are consequently known as toe knuckles in common speech. 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). The region of skin directly below the joints forms the ball of the foot.
The ligaments are the plantar and two collateral.
Movements
The movements permitted in the metatarsophalangeal joints are flexion, extension, abduction, adduction and circumduction.
