Effect of Stand-Alone Oblique Lateral Interbody Fusion (OLIF) in Treating Lumbar Spine Lesions

<bold>BACKGROUND:</bold> The aim of this study was to investigate the safety and early clinical results of stand-alone oblique lateral interbody fusion (OLIF) in the fusion of lumbar spine lesions and to explore the indications for surgery.<bold>MATERIAL AND METHODS:</bold> A total of 92 cases of lumbar spine lesions treated with stand-alone OLIF in 2 medical centers from October 2014 to December 2018 were retrospectively analyzed. We included 30 males and 62 females, ages 32-83 years.<bold>RESULTS:</bold> Our results showed that the operation time was 60.92 +/- 27.40 min (average 36.6 min) and the intraoperative blood loss was 68.22 +/- 141.6 ml (average 23.8 ml). The height of the intervertebral space was restored - before the operation (9.23 +/- 1.94 mm) and (12.68 +/- 2.01 mm) after the operation - and it was 10.18 +/- 2.14 mm at the last follow-up. There was a significant difference between the postoperative and preoperative values (t=9.27, P<0.0001), and there was also a significant difference between the final follow-up and postoperative comparison value (t=8.43, P<0.0001).<bold>CONCLUSIONS:</bold> The use of stand-alone OLIF in treating fusion of lumbar spine lesions showed excellent clinical efficacy and achieved the expected clinical improvements.
