Infections ostéoarticulaires à s. Deux nouveaux cas. Deux nouveaux cas

Introduction, - Propionibacterium acnes is an anaerobic germ, usually found as a saprophyte of the skin and the mucosa. It may be responsible for iatrogenic or spontaneous osteoarhritis. Exegesis. - We report two new cases of septic arthritis induced by Fl acnes: a case of iatrogenic spondylodiscitis and a case of spontaneous septic arthritis of the lumbar facet joints The two patients were immunocompetent, without acne. Conclusion. - Except for patients with criteria of the SAPHO syndrome (synovitis-acne-pustulosis-hyperostosis-osteomyelitis), osteoarthritis caused by Fl acnes is increasingly described. The number of these infections is probably underestimated because of the technical problems involved in isolating Fl acnes in the laboratory: (C) 2000 Editions scientifiques et medicales Elsevier SAS.
