Three- to six-year follow-up of stand-alone BAK cages implanted by a single surgeon.

Background Context: Multiple studies involving the outcomes of anterior interbody cages have been published, but the majority were by authors who designed the cage. No outcome studies with Bagby and Kuslich (BAK) cages implanted by a single-surgeon have either 3 years of follow-up or at least 25 patients.

Purpose: To determine the 3- to 6-year clinical outcomes, including fusion rate, revision rate, complications and functional status of patients who underwent placement of anterior, stand-alone BAK cages by a single surgeon.
