Lateral displacement of the great toe (HALLUX), producing deformity of the first METATARSOPHALANGEAL JOINT with callous, bursa, or bunion formation over the bony prominence.

The innermost digit of the foot in PRIMATES.

A condition caused by degenerative arthritis (see OSTEOARTHRITIS) of the METATARSOPHALANGEAL JOINT of the great toe and characterized by pain and limited dorsiflexion, but relatively unrestricted plantar flexion.

The articulation between a metatarsal bone (METATARSAL BONES) and a phalanx.

The five long bones of the METATARSUS, articulating with the TARSAL BONES proximally and the PHALANGES OF TOES distally.

A bony proliferation and articular degeneration of the first METATARSOPHALANGEAL JOINT that is characterized by pain and a progressive decrease in the dorsiflexion range of motion.

The articulation between the head of one phalanx and the base of the one distal to it, in each toe.

The forepart of the foot including the metatarsals and the TOES.

Any one of five terminal digits of the vertebrate FOOT.

The part of the foot between the tarsa and the TOES.

The surgical cutting of a bone. (Dorland, 28th ed)

Displacement of the great toe (HALLUX) towards the midline or away from the other TOES. It can be congenital or acquired.

Distortion or disfigurement of the foot, or a part of the foot, acquired through disease or injury after birth.

'Shoes' are not a medical term, but an item of footwear designed to provide protection, support, and comfort to the feet during various activities, although ill-fitting or inappropriate shoes can contribute to various foot conditions such as blisters, corns, calluses, and orthopedic issues.

Surgical reconstruction of a joint to relieve pain or restore motion.

Nodular bones which lie within a tendon and slide over another bony surface. The PATELLA (kneecap) is a sesamoid bone.

Applies to movements of the forearm in turning the palm backward or downward. When referring to the foot, a combination of eversion and abduction movements in the tarsal and metatarsal joints (turning the foot up and in toward the midline of the body).

A condition in which one or more of the arches of the foot have flattened out.

The distal extremity of the leg in vertebrates, consisting of the tarsus (ANKLE); METATARSUS; phalanges; and the soft tissues surrounding these bones.

The distance and direction to which a bone joint can be extended. Range of motion is a function of the condition of the joints, muscles, and connective tissues involved. Joint flexibility can be improved through appropriate MUSCLE STRETCHING EXERCISES.

Applies to movements of the forearm in turning the palm forward or upward. When referring to the foot, a combination of adduction and inversion movements of the foot.

Alterations or deviations from normal shape or size which result in a disfigurement of the foot occurring at or before birth.

The surgical fixation of a joint by a procedure designed to accomplish fusion of the joint surfaces by promoting the proliferation of bone cells. (Dorland, 28th ed)

Anatomical and functional disorders affecting the foot.

A condition characterized by a series of interrelated digital symptoms and joint changes of the lesser digits and METATARSOPHALANGEAL JOINTS of the FOOT. The syndrome can include some or all of the following conditions: hammer toe, claw toe, mallet toe, overlapping fifth toe, curly toe, EXOSTOSIS; HYPEROSTOSIS; interdigital heloma, or contracted toe.

Steel wires, often threaded through the skin, soft tissues, and bone, used to fix broken bones. Kirschner wires or apparatus also includes the application of traction to the healing bones through the wires.
