Hallux Rigidus

Hallux rigidus or stiff big toe is degenerative arthritis and stiffness due to bone spurs that affects the MTP joint at the base of the hallux. Hallux flexus was initially described by Davies-Colley in 1887 as a plantar flexed posture of phalanx relative to the metatarsal head. About the same time, Cotterill first used the term hallux rigidus.
