Hallux rigidus refers to stiffness (rigidus) of the joint at the base of the big toe (hallux) due to arthritis or ‘wear and tear’ of the smooth lining of the joint. This articulation in the forefoot is called the 1st metatarsophalangeal (MTP) joint. The most common cause of arthritis in this joint is due to trauma or repetitive injury. The natural history of this condition is usually gradual progression, but can be asymptomatic.
