Specifically, mechanical complications of rod fracture, instrumentation failures, and pseudarthrosis are still unsolved issues. To better improve these problems, oblique lateral interbody fusion at L5\/S1 (OLIF51) was introduced in 2015 at my institution. The objective of this study was to compare the clinical and radiologic outcomes of anterior\u2013posterior combined surgery for ASD between the use of OLIF51 and transforaminal interbody fusion (TLIF) at L5\/S1. Materials and Methods: A total of 117 ASD patients received anterior\u2013posterior correction surgeries either with the use of OLIF51 (35 patients) or L5\/S1 TLIF (82 patients). In both groups, L1\u20135 OLIF and minimally invasive posterior procedures of hybrid or circumferential MIS were employed. The sagittal and coronal spinal alignment and spino-pelvic parameters were recorded preoperatively and at follow-up. The quality-of-life parameters and visual analogue scale were evaluated, as well as surgical complications at follow-up. Results: The average follow-up period was thirty months (13\u201384). The number of average fused segments was eight (4\u201312). The operation time and estimated blood loss were significantly lower in OLIF51 than in TLIF. The PI-LL mismatch, LLL, L5\/S1 segmental lordosis, and L5 coronal tilt were significantly better in OLIF51 than TLIF. The complication rate was statistically equivalent between the two groups. Conclusions: The introduction of OLIF51 for adult spine deformity surgery led to a decrease in operation time and estimated blood loss, as well as improvement in sagittal and coronal correction compared to TLIF. The circumferential MIS correction and fusion with OLIF51 serve as an effective surgical modality which can be applied to many cases of adult spinal deformity.<\/jats:p>","DOI":"10.3390\/medicina60010107","type":"journal-article","created":{"date-parts":[[2024,1,8]],"date-time":"2024-01-08T03:49:04Z","timestamp":1704685744000},"page":"107","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Clinical and Radiologic Analysis of Minimally Invasive Anterior\u2013Posterior Combined Surgery for Adult Spinal Deformity: Comparison of Oblique Lateral Interbody Fusion at L5\/S1 (OLIF51) versus Transforaminal Interbody Fusion"],"prefix":"10.3390","volume":"60","author":[{"given":"Yoshihisa","family":"Kotani","sequence":"first","affiliation":[{"name":"Spine and Nerve Center, Department of Orthopaedic Surgery, Kansai Medical University Medical Center, Moriguchi, Osaka 570-8507, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atsushi","family":"Ikeura","sequence":"additional","affiliation":[{"name":"Spine and Nerve Center, Department of Orthopaedic Surgery, Kansai Medical University Medical Center, Moriguchi, Osaka 570-8507, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takahiro","family":"Tanaka","sequence":"additional","affiliation":[{"name":"Spine and Nerve Center, Department of Orthopaedic Surgery, Kansai Medical University Medical Center, Moriguchi, Osaka 570-8507, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takanori","family":"Saito","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Kansai Medical University, Hirakata, Osaka 573-1191, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"S70","DOI":"10.1093\/neuros\/nyw048","article-title":"Recent and emerging advances in spinal deformity","volume":"80","author":"Smith","year":"2017","journal-title":"Neurosurgery"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1007\/s00586-014-3542-1","article-title":"Impact on health related quality of life of adult spinal deformity (ASD) compared with other chronic conditions","volume":"24","author":"Ferrer","year":"2015","journal-title":"Eur.
