Summary.

We treated eighteen patients with chronic osteomyelitis by implanting pieces of antibiotic-impregnated calcium hydroxyapatite ceramic into a cavity produced after thorough surgical excision of necrotic tissue. Within three months the infected sites had all healed. During follow-up ranging from 24 to 75 months there was no recurrence of infection. Two of the patients had infected prosthetic joints which were successfully revised. Infection was controlled and incorporation of the ceramic material into host bone was demonstrated radiographically. We recommend the use of porous pieces of calcium hydroxyapatite impregnated with antibiotic as a new system for drug delivery in the treatment of chronic osteomyelitis.

Résumé.

Les auteurs rapportent le traitement de 18 patients atteints d’ostéomyélite chronique par excision chirurgicale suivie d’implantation de fragments d’hydroxyapatite de calcium imprégnés d’antibiotique. Tous les sites d’infection ont cicatrisé dans un délai de 3 mois. Pendant la période de suivi, allant de 24 à 75 mois, il n’y a pas eu de récidive de l’infection. 2 des patients avaient une infection sur prothèse articulaire qui ont été révisés avec succès. En plus du contrôle de l’infection, il a été constaté radiologiquement une incorporation de l’hydroxyapatite. Les auteurs recommandent donc l’utilisation des ces fragments poreux d’hydroxyapatite de calcium imprégnés d’antibiotique pour le traitement de l’ostéomyélite chronique.
