We also wanted to see if the spinopelvic parameters change with surgery and whether this change influences the outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>This was a prospective study on patients with lumbar spinal stenosis (20 patients) and LDH (20 patients) who underwent simple discectomy or decompressive surgery between November 2021 and May 2022. Visual Analog Scale (VAS) for back and leg pain, Oswestry Disability Index, and Japanese Orthopedic Association (JOA) score were performed before and 3 months after surgery. Spinopelvic parameters were measured on whole spine radiographs before and 3 months after surgery. On axial magnetic resonance images, paraspinal muscle volume and muscle\/fat ratios were calculated. All data were statistically analyzed with SPSS program.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>There was a significant improvement in VAS, Oswestry, and JOA scores after surgery. We observed that more preoperative paraspinal muscle mass was positively correlated with lumbar lordosis (LL) and negatively correlated with sagittal vertical axis (SVA), VAS leg scores, and Oswestry scores. Furthermore, we observed a positive correlation between preoperative SVA and VAS leg scores.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Despite limited number of patients, and shorter follow-ups, this prospective study demonstrates a correlation among the lumbar paraspinal muscle\/fat ratio, preoperative\/postoperative spinopelvic parameters, and surgical outcomes. Increased paraspinal muscle ratio was correlated with lower SVA values and increased LL; lower VAS leg scores; higher Oswestry scores which reflects better surgical outcomes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/jcvjs.jcvjs_40_23","type":"journal-article","created":{"date-parts":[[2023,9,18]],"date-time":"2023-09-18T05:32:07Z","timestamp":1695015127000},"page":"236-244","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Can lumbar paraspinal muscle\/fat ratio and spinopelvic parameters predict short-term outcomes after decompressive surgeries in lumbar disc herniation and lumbar spinal stenosis?"],"prefix":"10.4103","volume":"14","author":[{"given":"Habib Canberk","family":"Karakoc","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Reyhanli State Hospital, Hatay, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mehmet","family":"Zileli","sequence":"additional","affiliation":[{"name":"Sanko University Neurosurgery Department, Gaziantep, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Onur","family":"Yaman","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Memorial Bahcelievler Hastanesi, Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kemal","family":"Paksoy","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Memorial Bahcelievler Hastanesi, Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2023,9,18]]},"reference":[{"key":"R1-20240904","doi-asserted-by":"crossref","first-page":"135","DOI":"10.1186\/s12891-018-2059-x","article-title":"Methodological considerations in region of interest definitions for paraspinal muscles in axial MRIs of the lumbar spine","volume":"19","author":"Berry","year":"2018","journal-title":"BMC Musculoskelet Disord"},{"key":"R2-20240904","first-page":"115","article-title":"Management of back pain","volume":"29","author":"Porter","year":"1987","journal-title":"Crit Q"},{"key":"R3-20240904","doi-asserted-by":"crossref","first-page":"E344","DOI":"10.1097\/BRS.0b013e3181c91121","article-title":"Total sagittal spinal alignment in patients with lumbar canal stenosis accompanied by intermittent claudication","volume":"35","author":"Suzuki","year":"2010","journal-title":"Spine (Phila Pa 1976)"},{"issue":"Suppl 1","key":"R4-20240904","doi-asserted-by":"crossref","first-page":"S42","DOI":"10.1227\/01.neu.0000462077.50830.1a","article-title":"Implications of spinopelvic alignment for the spine surgeon","volume":"76","author":"Mehta","year":"2015","journal-title":"Neurosurgery"},{"key":"R5-20240904","doi-asserted-by":"crossref","first-page":"1961","DOI":"10.1097\/BRS.0b013e3181fef890","article-title":"Assessment of association between low back pain and paraspinal muscle atrophy using opposed-phase magnetic resonance imaging:A population-based study among young adults","volume":"36","author":"Paalanne","year":"2011","journal-title":"Spine (Phila Pa 1976)"},{"key":"R7-20240904","doi-asserted-by":"crossref","first-page":"1323","DOI":"10.1016\/j.mri.2012.05.001","article-title":"3D slicer as an image computing platform for the quantitative imaging network","volume":"30","author":"Fedorov","year":"2012","journal-title":"Magn Reson Imaging"},{"key":"R9-20240904","first-page":"1459","article-title":"Sagittal balance of the pelvis-spine complex and lumbar degenerative diseases","volume":"16","author":"Barrey","year":"2007","journal-title":"A comparative study about 85 cases.
