The purpose of this study is to compare outcomes of subjects undergoing multilevel lumbar fusion (MLF) surgery with and without the iFuse 3-D implants in the "bedrock" trajectory.


This is a multicenter randomized controlled, postmarket clinical study to determine the differences between subjects undergoing standard MLF surgery with S2AI fixation in the pelvis vs the additional placement of iFuse 3-D in the bedrock configuration during MLF surgery. Subjects will be monitored for sacroiliac (SI) joint pain and at two years post surgery a CT scan will be taken to assess S2AI screw loosening or any other findings.
