Clinical Outcomes of Lateral Lumbar Interbody Fusion with Percutaneous Pedicle Screw for Dialysis-Related Spondyloarthropathy

Abstract

We investigated the clinical outcomes of the lateral lumbar interbody fusion (LLIF) with percutaneous pedicle screw (PPS) procedure for dialysis-related spondyloarthropathy and lumbar degenerative disease. We retrospectively compared the clinical parameters of 9 patients (6 males, 3 females) with dialysis-related spondyloarthropathy (group D) and 9 patients (5 males, 4 females) with lumbar degenerative disease (group L) who were treated in our institution between April 2014 and April 2018. There were no differences between the two groups for operative time or total blood loss. However, there was a significant between-group difference in the peri- and postoperative complications. Three cases of endplate injury and one case of postoperative infection occurred in group D. There was no difference between the two groups in JOA score. One case in group D required reoperation because of postoperative cage subsidence. The clinical outcome of the procedure was acceptable for cases of dialysis-related spondyloarthropathy, making LLIF with PPS an effective treatment option for this patient group. However, further study is necessary regarding the indications for indirect decompression and the optimal postoperative therapy and adjuvant therapy for this procedure.
