Thoracic and lumbar spinal surgery under local anesthesia for patients with multiple comorbidities: a consecutive case series

Background: Although some patients with symptomatic spinal disease may benefit greatly from surgery, their multiple attendant comorbidities may make general anesthesia risky or contraindicated. However, there is scarce literature describing the efficacy and safety of local anesthesia to perform these operations. Here we report seven patients who successfully underwent spinal surgery utilizing local anesthesia to limit the risks and complications of general anesthesia.
