Data: Posterior lumbar interbody fusion (PLIF) becomes widely used surgical procedure to reduce pain and spinal instability resulting from some spinal diseases. Although this procedure is widely used, postoperative conditions such as good clinical outcome and spinal instability are still a matter of controversy. Maintenance of disc height and solid fusion significantly increased with PLIF with cage. Cage migration to the spinal canal is one of the most common cause of implant failure in mono-segmental lumbar interbody fusion.
