Data on pre- and postoperative back pain and leg pain (numerical rating scale [NRS] scale) were retrospectively collected from questionnaires with a return rate of 65% (n\u2009=\u200966). The complete cohort as well as patients with first-time surgery and re-decompression were analyzed separately. Patients were dichotomized to short-term follow-up (&lt; 100 weeks) and long-term follow-up (&gt; 100 weeks) postsurgery.<\/jats:p><jats:p>\n            Results\u2003Overall, both back pain (NRS 4.59 postoperative versus 7.89 preoperative; p\u2009&lt;\u20090.0001) and leg pain (NRS 4.09 versus 6.75; p\u2009&lt;\u20090.0001) improved postoperatively. The short-term follow-up subgroup (50%, n\u2009=\u200933) showed a significant reduction in back pain (NRS 4.0 versus 6.88; p\u2009&lt;\u20090.0001) and leg pain (NRS 2.49 versus 6.91: p\u2009&lt;\u20090.0001). Similar results could be observed for the long-term follow-up subgroup (50%, n\u2009=\u200933) with significantly less back pain (NRS 3.94 versus 7.0; p\u2009&lt;\u20090.0001) and leg pain (visual analog scale 3.14 versus 5.39; p\u2009&lt;\u20090.002) postoperatively. Patients with previous decompression surgery benefit significantly regarding back pain (NRS 4.82 versus 7.65; p\u2009&lt;\u20090.0024), especially in the long-term follow-up subgroup (NRS 4.75 versus 7.67; p\u2009&lt;\u20090.0148). There was also a clear trend in favor of leg pain in patients with previous surgery; however, it was not significant.<\/jats:p><jats:p>\n            Conclusions\u2003Decompression of lumbar spinal stenosis without fusion led to a significant and similar reduction of back pain and leg pain in a short-term and a long-term follow-up group. Patients without previous surgery benefited significantly better, whereas patients with previous decompression benefited regarding back pain, especially for long-term follow-up with a clear trend in favor of leg pain.<\/jats:p>","DOI":"10.1055\/s-0038-1669473","type":"journal-article","created":{"date-parts":[[2018,12,5]],"date-time":"2018-12-05T18:42:18Z","timestamp":1544035338000},"page":"081-087","source":"Crossref","is-referenced-by-count":7,"title":["Improvement of Back and Leg Pain after Lumbar Spinal Decompression without Fusion"],"prefix":"10.1055","volume":"80","author":[{"given":"Nicola","family":"Bongartz","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Medical Center University of Aachen, RWTH University, Aachen, NRW, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Blume","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Medical Center University of Aachen, RWTH University, Aachen, NRW, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hans","family":"Clusmann","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Medical Center University of Aachen, RWTH University, Aachen, NRW, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"M\u00fcller","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Medical Center University of Aachen, RWTH University, Aachen, NRW, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthias","family":"Geiger","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Medical Center University of Aachen, RWTH University, Aachen, NRW, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2018,12,5]]},"container-title":["Journal of Neurological Surgery Part A: Central European Neurosurgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0038-1669473.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,2,26]],"date-time":"2019-02-26T19:22:22Z","timestamp":1551208942000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0038-1669473"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,12,5]]},"references-count":0,"journal-issue":{"issue":"02","published-online":{"date-parts":[[2019,2,26]]},"published-print":{"date-parts":[[2019,3]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0038-1669473","relation":{},"ISSN":["2193-6315","2193-6323"],"issn-type":[{"value":"2193-6315","type":"print"},{"value":"2193-6323","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,12,5]]}}}
