This study is a prospective, non-concurrent, multicenter study to compare the clinical and radiographic outcomes of smooth PEEK, 3D-printed titanium, and Porous PEEK interbody implants when used with cancellous allograft chips with BMA or cellular allograft in subjects who undergo XLIF surgery at one or two levels. To minimize selection bias, all consecutive patients at a given site who meet eligibility requirements will be asked to consent to participate in the study. These patients will present with degenerative conditions in the lumbar spine that are amenable to surgical treatment and will be screened prior to study enrollment. Once enrolled into the study, subjects will undergo their XLIF operation using one of the 3 previously noted interbody implants based on a non-concurrent enrollment schedule. The bone graft material used inside the interbody implant will be randomly assigned between cancellous allograft chips with BMA or cellular allograft prior to surgery based on surgeon investigators' equipoise for the effectiveness of both bone graft materials. Subjects will be followed for 24 months following surgery to determine the number of study subjects that are solidly fused at or before 24 months postoperatively.
