Posterior lumbar interbody fusion for degenerative spondylolisthesis: restoration of sagittal balance using insert-and-rotate interbody spacers

This series suggests that PLIF for degenerative spondylolisthesis using an insert-and-rotate technique can yield high levels of patient satisfaction with low levels of complications and substantial deformity correction using a posterior only approach. Longer-term outcome studies are required regarding the relevance of the restoration of spinal balance.
