2012 Young Investigator Award winner: The distribution of body mass as a significant risk factor for lumbar spinal fusion postoperative infections.

摘要: Study design A retrospective review. Objective The purpose of this study was to determine the role in body habitus and weight distribution on developing a surgical site infection (SSI). Summary background data SSI after lumbar spine surgery remains significant cause morbidity. literature demonstrates an increased risk postoperative infections associated with obesity, diabetes, multilevel surgeries. Methods review performed consecutive cohort 298 adult patients who underwent fusion surgeries between 2006 2008 at Duke University Medical Center. Previously identified factors (i.e., number levels, mass index [BMI]) were collected, as well horizontal distance from lamina skin surface (measured L4) thickness subcutaneous fat site. Results Among patients, 24 (8%) had infections. Of previously factors, levels (P = 0.0078) found be significantly infections, whereas BMI 0.16) diabetes 0.13) not statistically significant. Obesity (BMI ≥30) 0.025), 0.046), 0.035) for SSI. Conclusion Our findings suggest that obese is more predictive than absolute deserves attention preoperative evaluation.
