Infection in neuro-muscular scoliosis deformity correction.

Assess the outcome of a standardised protocol for the treatment of post-operative wound infection in patients undergoing deformity correction for neuro-muscular scoliosis (NMS). Retrospective review of 443 consecutive patients with a minimum 18 months' follow-up, following a primary posterior deformity correction for NMS. In patients who developed a wound complication, the patient demographic and comorbidities, causative pathogen, number of re-operations, length of stay (LOS), rate of cure, and complications were analysed. Forty-four patients (9.9%) developed a wound infection. Marginally more infections were mono-microbial (23) than poly-microbial (21). Coagulase negative staphylococcus and Staphylococcus aureus were the most commonly cultured pathogens. Seventeen patients were treated with antibiotics alone, while 27 patients also required surgical debridement. The average LOS for those treated with antibiotics alone was 12 days (range: 9-15 days), in contrast to those requiring debridement, which was 35 days (range: 35-70 days). All patients were cured from their infection and ultimately achieved fusion. Infection is common in NMS deformity correction. This is marginally more common as a mono-microbial than poly-microbial infection with most pathogens being staphylococcal in origin. Our defined treatment strategy resulted in a cure for all patients and capacity for all patients to achieve fusion.
