This is a type of arthritis that affects the base of the big toe. It forms in the metatarsophalangeal joint (we call it the "MTP" joint). With hallux rigidus, the protective cartilage on the ends of these bones wears away. Bone rubs against bone. Bony growths called "bone spurs" may form. Your toe stiffens, and this can make walking uncomfortable.
