      <p><b>Purpose</b> To investigate potential associations between preoperative MRI findings and patient reported outcome measures (PROMs) after surgery for lumbar spinal stenosis (LSS). <p><b>Methods</b> The NORDSTEN trial included 437 patients. We investigated the association between preoperative MRI findings such as morphological grade of stenosis (Schizas grade), quantitative grade of ...

      Background We aim to investigate associations between preoperative radiological findings of lumbar foraminal stenosis with clinical outcomes after posterior microsurgical decompression in patients with predominantly central lumbar spinal stenosis (LSS).<p> <p>Methods The study was an additional analysis in the NORDSTEN Spinal Stenosis Trial. In total, 230 men and 207 women (mean age 66.8 (SD ...

    • Postoperative Dural Sac Cross-Sectional Area as an Association for Outcome After Surgery for Lumbar Spinal Stenosis: Clinical and Radiological Results From the NORDSTEN-Spinal Stenosis Trial 

      Hermansen, Erland; Myklebust, Tor Åge; Weber, Clemens; Brisby, Helena; Austevoll, Ivar Magne; Hellum, Christian; Storheim, Kjersti; Aaen, Jørn Ståle; BANITALEBI, HASAN; Brox, Jens Ivar; Grundnes, Oliver; Rekeland, Frode Gurvin; Solberg, Tore; Franssen, Eric; Indrekvam, Kari (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-15)
      Objective - The aim was to investigate the association between postoperative dural sac cross-sectional area (DSCA) after decompressive surgery for lumbar spinal stenosis and clinical outcome. Furthermore, to investigate if there is a minimum threshold for how extensive a posterior decompression needs to be to achieve a satisfactory clinical result.<p> <p>Summary of Background Data - There is ...
