RESUMO
BACKGROUND: The purpose of this study was to evaluate the clinical and radiologic outcome of chronic hematogenous osteomyelitis (CHOM) in children, treated with single-stage debridement and dead space management using antibiotic impregnated calcium sulphate pellets. METHODS: The authors retrospectively evaluated a consecutive series of 34 patients who presented with CHOM from 2011 to 2017. In each case, CHOM was classified according to the Beit CURE classification. Following thorough surgical debridement, the resulting dead space in the bone was filled with the antibiotic impregnated beads before primary closure. RESULTS: Of the 31 patients available for follow up, effective regeneration of bone was confirmed in all cases, with radiographic bone healing typically observed at around 12 weeks. None of the children required reoperation for infection and none had recurrence of infection at the time of final review. The beads were completely absorbed within 3 months. No systemic adverse reactions to the local delivery of antibiotics were observed in this study. CONCLUSIONS: The authors found that single-stage debridement in conjunction with antibiotic impregnated calcium sulphate was an effective means of treating CHOM in children, with effective eradication of infection in every case. LEVEL OF EVIDENCE: Level IV-Retrospective case series. See instructions for authors for a complete description of levels of evidence.
