Hallux Rigidus
Pronunciation: HAL-uks RIJ-ih-dus
A degenerative condition of the first metatarsophalangeal joint characterised by painful limitation or complete loss of dorsiflexion at the great toe.
Full Definition
Hallux rigidus is a progressive arthritic condition affecting the first metatarsophalangeal joint, resulting in stiffness, osteophyte formation, and restricted dorsiflexion during the propulsive phase of gait. It is distinct from hallux limitus, which describes partial limitation of motion at the same joint. In orthotic practice, it is managed through stiff-soled footwear modifications and carbon-fibre insoles that limit toe extension. Editors working on clinical documents must preserve this distinction and not use hallux rigidus and hallux limitus interchangeably. Both terms are always presented in roman type in modern clinical writing.
Usage
Usage note: Not synonymous with hallux limitus; hallux rigidus implies complete or near-complete loss of dorsiflexion, while hallux limitus implies partial restriction.
