Nevertheless, 30%\u201340% of patients do not have a significant benefit after surgery\u2014probably due to different anatomical preconditions. The sagittal profile types (SPTs 1\u20134) defined by Roussouly based on different spinopelvic parameters have been shown to influence spinal degeneration and surgical results. The aim of this study was to investigate the influence of the SPT on the clinical outcome in patients with LSS who were treated with MD.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>The authors retrospectively investigated 100 patients with LSS who received MD. The patients were subdivided into 4 groups depending on their SPT, which was determined from preoperative lateral spinal radiographs. The authors analyzed pre- and postoperative outcome scales, including the visual analog scale (VAS), walking distance, Oswestry Disability Index, Roland-Morris Disability Questionnaire, Odom\u2019s criteria, and the 36-Item Short Form Health Survey score.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>Patients with SPT 1 showed a significantly worse clinical outcome concerning their postoperative back pain (VAS<jats:sub>back-SPT 1<\/jats:sub> = 5.4 \u00b1 2.8; VAS<jats:sub>back-SPT 2<\/jats:sub> = 2.6 \u00b1 1.9; VAS<jats:sub>back-SPT 3<\/jats:sub> = 2.9 \u00b1 2.6; VAS<jats:sub>back-SPT 4<\/jats:sub> = 1.5 \u00b1 2.5) and back pain\u2013related disability.

Therefore, the indication for MD should be provided carefully, fusion can be considered, and other possible reasons for back pain should be thoroughly evaluated and treated.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2017.3.spine161269","type":"journal-article","created":{"date-parts":[[2017,9,1]],"date-time":"2017-09-01T14:02:25Z","timestamp":1504274545000},"page":"552-559","source":"Crossref","is-referenced-by-count":26,"title":["The sagittal spinal profile type: a principal precondition for surgical decision making in patients with lumbar spinal stenosis"],"prefix":"10.3171","volume":"27","author":[{"given":"Simon Heinrich","family":"Bayerl","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Charit\u00e9 Universit\u00e4tsmedizin Berlin; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Florian","family":"P\u00f6hlmann","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Charit\u00e9 Universit\u00e4tsmedizin Berlin; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tobias","family":"Finger","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Charit\u00e9 Universit\u00e4tsmedizin Berlin; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00f6rg","family":"Franke","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Klinikum Magdeburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Johannes","family":"Woitzik","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Charit\u00e9 Universit\u00e4tsmedizin Berlin; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Vajkoczy","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Charit\u00e9 Universit\u00e4tsmedizin Berlin; and"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Spine (Phila Pa 1976) J","first-page":"2373","article-title":"Individual and contextual characteristics as determinants of sagittal standing posture: a population-based study of adults","volume":"14","author":"Ara\u00fajo F","year":"2014","unstructured":"Ara\u00fajo F, Lucas R, Alegrete N, Azevedo A, Barros H: Individual and contextual characteristics as determinants of sagittal standing posture: a population-based study of adults.
