Cervical spine fusion is performed for various indications in patient populations ranging from young and healthy to aged and frail. The choice of surgical approach is affected not only by disease pathoanatomy, but also by age, medical comorbidities, and the number of involved levels. Anterior fusion is more common for single-level pathology in relatively young, healthy patients; and posterior fusion is typically performed on older, more comorbid patients with multilevel disease. Consequently, retrospective comparisons of surgical approaches for cervical fusion will be impacted by this bias, and the optimal management of multilevel cervical spine pathology remains ambiguous with surgeon preference and experience playing a significant role in choice of procedures. ⋯ This nationwide study defines the incidence of mortality and the frequency of inpatient complications encountered during multilevel cervical fusion. The results suggest that immediate morbidity from anterior approaches is less than those undergoing posterior fusion. Prospective analysis is required to evaluate if these findings remain significant in a randomized study population. Further, these results represent only perioperative complications. However, based on the data presented herein, when confronted with the patient requiring a four-level cervical fusion, the anterior approach may offer a less risky and less costly option.
