[Management of deep wound infections in spinal lumbar fusions].

The rate of deep wound infections in spinal lumbar fusions is around 0.7% to 11.6%, being one of the causes of morbidity in acute phase. The aim of this study was to evaluate the management of spinal infection after internal lumbar fusions. Two hundred and sixty patients, who underwent to spinal surgery with lumbar fusion and iliac bone grafting, were analized, from January 1997 to January 2005. Wound infection was observed in eight (3%) cases. The average of age was 56 years, with a higher prevalence in males (5 patients). Most prevalent was Staphylococcus aureus in 6 patients. The treatment was done by intravenous antibiotic therapy folowed by oral therapy and local irrigation. The average time of hospitalization was 35.8 days. It was possible to erradicate infection without removal of instrumentation in all patients.
