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 ...
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 ". The rest of the toes each have three phalanx bones (proximal, middle, and ...
Metatarsophalangeal joint sprain. Anatomy human foot. Specialty. Podiatry. A metatarsophalangeal joint sprain is an injury to the connective tissue between the foot and a toe (at a metatarsophalangeal joint, one of the joints in the ball of the foot). When the big toe is involved, it is known as " turf toe ". [1][2]
The metatarsal bones or metatarsus (pl.: metatarsi) are a group of five long bones in the midfoot, located between the tarsal bones (which form the heel and the ankle) and the phalanges (toes). Lacking individual names, the metatarsal bones are numbered from the medial side (the side of the great toe): the first, second, third, fourth, and ...
Tarsometatarsal joints. The tarsometatarsal joints (Lisfranc joints) are arthrodial joints in the foot. The tarsometatarsal joints involve the first, second and third cuneiform bones, the cuboid bone and the metatarsal bones. The eponym of Lisfranc joint is 18th–19th-century surgeon and gynecologist Jacques Lisfranc de St. Martin.
The arch is further supported by the plantar aponeurosis, by the small muscles in the sole of the foot (short muscles of the big toe), by the tendons of the tibialis anterior and posterior and fibularis longus, flexor digitorum longus, flexor hallucis longus and by the ligaments of all the articulations involved.

The first metatarsal bone is the bone in the foot just behind the big toe. The first metatarsal bone is the shortest of the metatarsal bones and by far the thickest and strongest of them. [ 1 ] Like the four other metatarsals, it can be divided into three parts: base, body and head. The base is the part closest to the ankle and the head is ...
Bunion. A bunion, also known as hallux valgus, is a deformity of the MTP joint connecting the big toe to the foot. [2] The big toe often bends towards the other toes and the joint becomes red and painful. [2] The onset of bunions is typically gradual. [2] Complications may include bursitis or arthritis.
