Khan JM, Basques BA, Harada GK, et al. - In this retrospective cohort analysis of 1,184 individuals who underwent posterolateral lumbar fusion from 2011 to 2018, investigators assessed the clinical and radiographic outcomes in various age cohorts after lumbar spinal fusion. A total of 850 people were involved, 330 young (38.80%), 317 middle-aged (37.30%), and 203 senior (23.90%). Irrespective of having greater comorbidities, and longer length of stay, senior people had notable advancement in patient-reported clinical outcomes. Nonetheless, across all cohorts, provided a common lack of accomplishment of minimal clinically important differences, these findings imply that in the management of people with refractory radiculopathic and/or neurogenic claudication symptoms, there is a necessity for a critical re-assessment of the role of lumbar spinal fusion
