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.
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 ...
In anatomy, a sesamoid bone (/ ˈsɛsəmɔɪd /) [1][2] is a bone embedded within a tendon or a muscle. [3] Its name is derived from the Greek word for ' sesame seed', indicating the small size of most sesamoids. Often, these bones form in response to strain, [4] or can be present as a normal variant. The patella is the largest sesamoid bone in ...
Tarsal tunnel syndrome (TTS) is a nerve compression syndrome or nerve entrapment syndrome causing a painful foot condition in which the tibial nerve is entrapped as it travels through the tarsal tunnel. [1][2] The tarsal tunnel is found along the inner leg behind the medial malleolus (bump on the inside of the ankle).
Skeleton of left foot. Lateral aspect. Metatarsals shown in purple. 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 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 ...
Metatarsalgia. Metatarsalgia, literally 'metatarsal pain' and colloquially known as a stone bruise, is any painful foot condition affecting the metatarsal region of the foot. This is a common problem that can affect the joints and bones of the metatarsals. Metatarsalgia is most often localized to the first metatarsal head – the ball of the ...
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]
