Hallux rigidus |
| Synonyms |
Arthritis of the big toe |
| Definitions |
Osteoarthritis of the metatarsophalangeal joint of the first toe. Hallux rigidus is characterised by arthralgia, which is usually worsened by walking. With time the joint enlarges and the symptoms become more pronounced with pain at the dorsal bony prominence of the first metatarsophalengeal joint (MTPJ) and decreased range of motion, especially dorsiflexion. In this process the destruction of the cartilage commonly starts at the dorsal portion of the metatarsal head and the bony prominence might impinge against the proximal phalanx.. Physical examination usually shows a painful, tender and swollen first MTPJ with limited motion and pain usually when dorsiflexed. Typical radiographic findings are asymmetric joint narrowing and a flattened metatarsal head. With advancement of the disease more of the joint surface is involved and subchondral cysts, sclerosis and bony proliferation at the joint margins occur and the joint narrowing progresses [PMID:24649409]. |
