Introduction: We have performed simultaneous parallel anterior and posterior combined lumbar spine surgery under intraoperative CT navigation (SPAPS) or minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for degenerative lumbar disease. The purpose of this study was to compare the clinical outcomes of SPAPS with MIS-TLIF.
Method: A total of 40 patients who underwent either of the two type of elective surgeries for degenerative lumbar disease at our hospital were retrospectively reviewed. Eighteen patients who underwent SPAPS (group S) and 22 patients who underwent MIS-TLIF (group T) from April, 2016 to December, 2018 were enrolled. All patients were postoperatively followed up for a minimum period of 6 months. The average age of group S patients was 62.3 years and that of group T was 67.0 years. The following items were evaluated preoperatively and at 6 months after surgery: operative time, intraoperative blood loss, perioperative complications, Japanese Orthopaedic Association Back Pain Evaluation Questionnarie (JOABPEQ), visual analog scale (VAS) score, and profit ratio.
Results: Operative time in groups S and T was 113.8 and 159.5 min, respectively. Intraoperative blood loss volume was 72 ml in group S and 132.8 ml in group T. None of the cases in either group had perioperative complications. The JOABPEQ indicated significant improvements in Low back pain, Lumbar ability, Walking ability, Social life ability and Mental health in group S and significant improvements in Low back pain, Walking ability, Social life ability and Mental health in group T. VAS scores in both groups of group S and T were significantly improved in all evaluation items. Operative time was shorter in group S than in group T. Low back pain according to the JOABPEQ was significantly improved in group S as compared to group T, as was the VAS score of leg numbness. The profit ratio of group S was significantly higher than that of group T, at 53% and 42%, respectively.
Conclusion: We compared the clinical outcomes of SPAPS and MIS-TLIF. This study showed that group S had good results in terms of operative time, low back pain, leg numbness, and profit ratio.
