Foot Conditions A-Z
Hallux rigidus is a condition in which the big toe becomes stiff, inflexible and painful, often because of degenerative arthritis at the toe joint—specifically, at the first metatarsophalangeal joint (MPJ), where the first metatarsal bone and proximal phalange of the big toe meet. Bone spurs may also form on the dorsal (top) side of the joint.
The condition is closely related to hallux limitus, in which there is stiffness and pain in the MPJ, but still some limited ability to move the big toe. Hallux limitus is often an early manifestation of hallux rigidus.
