A deformity of the big toe in which the joint at the base projects out from the foot, and the top of the toe turns inwards.
The condition is more common in women, because it is usually associated with wearing narrow, pointed, high-heeled shoes, but it may be caused by an inherited weakness in the joint.
A hallux valgus often leads to formation of a bunion or to osteoarthritis in the joint, causing pain and limiting foot movement.
Severe deformity may be corrected by osteotomy or arthrodesis.
Outward displacement of the great toe – always associated with a bunion (see CORNS AND BUNIONS). It is due to the pressure of footwear on an unduly broad foot. In adolescents, this broad foot is inherited; in adults it is due to splaying of the foot as a result of loss of muscle tone. The bunion is produced by pressure of the footwear on the protruding base of the toe. In mild cases the wearing of comfortable shoes may be all that is needed. In more severe cases the bunion may need to be removed, while in the most severe the operation of ARTHROPLASTY may be needed.
the most common foot deformity, usually affecting women, in which the big toe is displaced towards the others (i.e. away from the midline); it is associated with a *bunion. The second toe may become crowded by the big toe and a *hammer toe deformity often results. Treatment includes modified footwear and surgery.
Sti?ness of the joint between the great toe and the foot, which induces pain on walking. It is usually due to a crush injury or stubbing of the toe. Such stubbing is liable to occur in adolescents with a congenitally long toe. If trouble-some, the condition is treated by an operation to create a false joint.... hallux rigidus
This term means literally knock-kneed, and is a bending inward at the knees (genu valgum), or at the ankle, as occurs in FLAT-FOOT (pes planus).... valgus
