The interphalangeal joints of the foot are the joints between the phalanx bones of the toes in the feet. Since the great toe only has two phalanx bones ( proximal and distal phalanges), it only has one interphalangeal joint, which is often abbreviated as the " IP joint ".

A hammer toe, hammertoe or contracted toe is a deformity of the muscles and ligaments of the proximal interphalangeal joint of the second, third, fourth, or fifth toe, bending it into a shape resembling a hammer. In the early stage, a flexible hammertoe is movable at the joints; a rigid hammertoe joint cannot be moved and usually requires ...
The joints between each phalanx are the interphalangeal joints. The proximal phalanx bone of each toe articulates with the metatarsal bone of the foot at the metatarsophalangeal joint . Each toe is surrounded by skin, and present on all five toes is a toenail .
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.
The thumb and large toe do not possess a middle phalanx. The distal phalanges are the bones at the tips of the fingers or toes. The proximal, intermediate, and distal phalanges articulate with one another through interphalangeal joints of hand and interphalangeal joints of the foot. [4]: 708–711 : 708–711
The MTP joint of the first toe differs from those of the other toes in that other muscles act on the joint, and in the presence of two sesamoid bones. The plantar plate is firm but flexible fibrocartilage with a composition similar to that found in the menisci of the knee (composed roughly of 75% type-I collagen ), and can thus withstand ...
The feet of a newborn infant A woman's foot, decorated with nail polish and henna, and wearing a metti on the second toe, for her wedding. The human foot is a strong and complex mechanical structure containing 26 bones, 33 joints (20 of which are actively articulated), and more than a hundred muscles, tendons, and ligaments. [2]
