The articulation between a metatarsal bone (METATARSAL BONES) and a phalanx.
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.
Foot Deformities, Acquired
Hammer Toe Syndrome
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.
Anatomical and functional disorders affecting the foot.
Any one of five terminal digits of the vertebrate FOOT.
Range of Motion, Articular
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.
The distal extremity of the leg in vertebrates, consisting of the tarsus (ANKLE); METATARSUS; phalanges; and the soft tissues surrounding these bones.
A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated.
Polymers of silicone that are formed by crosslinking and treatment with amorphous silica to increase strength. They have properties similar to vulcanized natural rubber, in that they stretch under tension, retract rapidly, and fully recover to their original dimensions upon release. They are used in the encapsulation of surgical membranes and implants.
