Study Design: Retrospective clinical study.
Objectives: We report the new minimally invasive technique and its clinical results of oblique lumbar interbody fusion (OLIF) combined with central decompression using biportal endoscopic spinal surgery (BESS).
Summary of Literature Review: The OLIF procedure is one of the minimally invasive spine surgeries and is being frequently attempted recently to treat lumbar degenerative disease. It has been reported that it effectively decompresses foraminal stenotic lesions indirectly by inserting a large cage anteriorly, which reduces spondylolisthesis and widens the disc space. However, OLIF has limited effect for severe central canal stenosis, since it cannot achieve direct decompression. Therefore, authors report a new minimally invasive technique of OLIF combined with direct central decompression using BESS for severe central stenosis along with its clinical results as a pilot study.
Materials and Methods: For patients who were candidate for fusion surgery due to spondylolisthesis (more than one segment) or foraminal stenosis, authors performed OLIF and central decompression using BESS simultaneously, when the patients had concomitant severe central canal stenosis. From June to December, 2017, 8 patients (16 levels) were enrolled, the operative time, blood loss, complications and clinical results have been evaluated. The clinical results were analyzed by Visual analog scale (VAS) scores, Oswestry disability index (ODI) and Roland Morris Disability Questionnaire (RMDQ) of preoperative, 1month, 3month postoperative and final follow-up.
Results: Mean operative time and blood loss were 238.4 minutes and 173.3ml, respectively. In all cases, there were no operative complications, and mean follow-up period was 7.1 months. The mean back VAS, lower extremity VAS, ODI, and RMDQ at the final follow-up were improved from 5.4±2.4 to 2.0±0.9, 7.0±1.1 to 1.6±1.7, 64.2±11.8 to 44.2±10.6, and from 17.5±4.2 to 12.9±4.0.
Conclusion: A new combination technique of OLIF and BESS for direct decompression can be regarded as effective alternative procedure to treat the foraminal and central stenotic lesions of lumbar degenerative disease.
