osteochondritis

Orthopedics Inflammation of bone and joint surfaces–usually aseptic; note: A legacy of the German school of medicine was eponymic immortalization of osteochondritis in each joint

Osteochondritis eponyms

Freiberg's disease–metatarsal head

Haglund's disease–calcaneus

Köhler's disease–tarsal-navicular bones

Legg-Calve-Perthes disease–femoral head

Osgood-Schlatter disease–tibial tubercle

Panner's disease–humeral head

Sinding-Larsen-Johannson disease–patella

Thiemann's disease–metacarpal and metatarsal bones

Legg-Cal·vé-Per·thes dis·ease

(leg kahl-vē pār'tĕz di-zēz')

Self-limiting pediatric disease of the femoral head caused by poor circulation. The degeneration of the femoral head is followed by regeneration and absorption of bone. The process may take 4 years. Usually found in children aged 4-8 years.
Synonym(s): coxa plana.

Legg-Calvé-Perthes disease

an idiopathic necrosis and lysis of the femoral head; occurs in young, small-breed dogs. Lameness of varying severity occurs and a degenerative arthropathy follows. Surgical removal of the femoral head is the usual treatment. Called also Legg's disease, Legg-Calvé disease, Perthes disease.
