Description
Summary:Complex spinal surgery is known to be at risk of complications. Surgical site infection is a serious complication in spine surgery and its frequency is significantly increased in adult spinal deformity correction. The aim of this study is to identify patients’ characteristics and risk factors of surgical site infection (SSI) following an osteotomy. This is a single-center retrospective study of patients who underwent an osteotomy between January 2015 and December 2017. Surgical site infection diagnosis was based upon patient's clinical evidence of infection, biologic parameters, microbiological criteria and/or image findings. In total, 102 patients were eligible and 70 were women (68.6%). Mean age was 65 years old (27–83 years) and mean body mass index (BMI) was 26.14kg.m−2 (18.4–44.1). Eleven patients were in the SSI group and 91 in the No-SSI group. The mean Schwab grade was 1.5 (1–4) in the SSI group vs. 1.4 (1–5) in the No-SSI group (P=0.435). The mean operative time was on 201.9 minutes (67–377). Mean length of stay was 20.6 days (10–73) in the SSI group vs. 15 days (5–44) in the No-SSI group (P=0.041). Favorable outcome was found in 10 patients (90.9%) in the SSI group. Correction surgery for adult spinal deformity with osteotomies carries a high risk of complications specially SSI. Identification of risk factors, prevention and medical management of SSI should be well assessed. La chirurgie de la déformation rachidienne présente des complications importantes. L’infection du site opératoire est une des complications graves et sa fréquence est considérablement accrue dans ce type de chirurgie. L’objectif de cette étude est d’identifier les caractéristiques des patients et les facteurs de risque d’infection du site opératoire (ISO) chez les patients ayant bénéficié d’ostéotomie vertébrale. La cohorte d’étude était composée de tous les patients ayant bénéficié d’une ostéotomie pour déformation de la colonne vertébrale entre janvier 2015 et décembre 2017 dans notre institution. Le diagnostic de l’infection du site opératoire était basé sur des éléments cliniques, des paramètres biologiques, microbiologiques et/ou d’imagerie. Au total, 102 patients étaient éligibles dont 70 femmes (68,6 %). L’âge moyen était de 65 ans (27–83 ans) et l’indice de masse corporelle (IMC) moyen était de 26,14kg.m−2 (18,4–44,1). Onze patients étaient dans le groupe ISO et 91 dans le groupe non-ISO. Aucune différence significative n’a été constatée entre les 2 groupes concernant
