Tarsoclasis - surgical fracture of the tarsus of the foot.

Tarsus - the seven bones composing the articulation between the foot and leg, including the talus, calcaneus, navicular bone, cuboid bone, and medial, intermediate, and lateral cuneiform bones.

Tendinitis: Inflammation of a tendon (the tissue by which muscle attaches to bone). Tendinitis most commonly occurs as a result of injury, such as to the tendons around the shoulder or elbow.

Tinel's sign: An examination test that is used by doctors to detect an irritated nerve. Tinel's sign is performed by lightly banging (percussing) over the nerve to elicit a sensation of tingling or "pins and needles" in the distribution of the nerve.

For example, in a person with carpal tunnel syndrome where the median nerve is compressed at the wrist, Tinel's sign is often "positive" and causes tingling in the thumb, index, and middle fingers.

Tinel's sign is sometimes referred to as "distal tingling on percussion" or DTP.

The damage is to the capsule of the joint (the first metatarsophalangeal joint) and the ligaments that connect the big toe to the foot. Hyperflexible shoes predispose to the injury. The big toe is painful, tender and swollen. Treatment is with icing, rest and anti-inflammatory medication. Taping of the big toe and a stiff insole insert in the shoe may help prevent hyperextension of the toe. Turf toe is so named for its occurrence on the artificial playing surfaces used in American football. Turf toe also occurs in other sports played on artificial turf, in grass sports, and the martial arts. Also known medically as a metatarsophalangeal joint sprain.
