The authors report 82 cases of osteomyelitis treated and followed up at the CHU Le Dantec, from March 1979 to September 1991. The patients were young, with an average age of 18 and a half years. Some susceptibility factors were identified: malnutrition (12.20%) and sickle cell anemia (26.83%). The infection was more frequently located on long bones of the lower limber (62.77%) and mainly on the metaphysis. Fistula forms with sequestra were the most frequent ones. Sixty-six patients were healed right after the first operation, 13 after two operations, 3 after three operations, the laters were mainly relapsing cases related to insufficient curreting of the infected bone or persisting sequestrum.
