Researchers collected data for spinal surgery performed between 1998 and 2010, identifying 261,256 entries for primary spinal fusion. Patients undergoing anterior spinal fusion and anterior/posterior spinal fusion were significantly younger and had lower comorbidity instances than patients undergoing posterior spinal fusions.
Procedure-related complications occurred among 18.7 percent of anterior spinal fusion patients, 15.7 percent of posterior spinal fusion patients and 23.8 percent of anterior/posterior spinal fusion patients. Adjusted risk factors for hospital mortality include male gender, increasing age and more comorbidities.
