HALLUX RIGIDUS

Hallux rigidus occurs as two distinct varieties.

1. The adolescent type is due to synovitis of the metatarsophalangeal joint following injury,
 and is associated with muscular with spasm. There are no radiological changes. It is relieved by wearing a metatarsal bar 3/4 inch (2cm) wide and 1/2 inch (1.25cm) thick.

2. The adult type is nothing more than non-articular osteoarthritis, sometimes precipitated by injury. The limitation of movement is due to interlocking of osteophytes, and also to flattening of the metatarsal head. Treatment is by operation, the Keller procedure being the one most widely employed. In this operation the painful rigid toe is replaced by a pseudarthrosis at the metatarsophalangeal joint.
