The present study investigates outcomes in patients undergoing elective primary versus revision fusion surgery for lumbar degenerative pathologies with the use of a large population based database. ⋯ The association of a likely postoperative complication in patients undergoing revision lumbar spine fusion compared with those undergoing primary fusion procedures at the same region of the spine is quantified. Our analysis provides baseline estimates that could aid in preoperative risk stratification and as an adjunct in patient education and counseling, and policy makers for higher reimbursements for these sicker patients.
