Clinical outcome after surgery for lumbarspinal stenosis in patients with insignificantlower extremity pain. A prospective cohortstudy from the Norwegian registry for spine surgery
Hermansen, Erland; Myklebust, Tor Åge; Austevoll, Ivar Magne; Rekeland, Frode; Solberg, Tore; Storheim, Kjersti; Grundnes, Oliver; Aaen, Jørn Ståle; Brox, Jens Ivar; Hellum, Christian; Indrekvam, Kari (Peer reviewed; Journal article, 2019-01-22)Background: Spinal stenosis is a clinical diagnosis in which the main symptom is pain radiating to the lower extremities, or neurogenic claudication. Radiological spinal stenosis is commonly observed in the population and ... -
Comparable Increases in Dural Sac Area After Three Different Posterior Decompression Techniques for Lumbar Spinal Stenosis: Radiological Results From a Randomized Controlled Trial in the NORDSTEN Study
Hermansen, Erland; Austevoll, Ivar Magne; Hellum, Christian; Storheim, Kjersti; Myklebust, Tor Åge; Aaen, Jørn Ståle; Banitalebi, Hasan; Anvar, Masoud; Rekeland, Frode; Brox, Jens Ivar; Franssen, Eric; Weber, Clemens; Solberg, Tore; Haug, Knut Jørgen; Grundnes, Oliver; Brisby, Helena; Indrekvam, Kari (Journal article; Peer reviewed, 2020)Purpose: To investigate changes in dural sac area after three different posterior decompression techniques in patients undergoing surgery for lumbar spinal stenosis. Decompression of the nerve roots is the main surgical ... -
Decompression alone versusdecompression with instrumental fusionthe NORDSTEN degenerativespondylolisthesis trial (NORDSTEN-DS); study protocol for a randomized controlled trial
Austevoll, Ivar Magne; Hermansen, Erland; Fagerland, Morten; Rekeland, Frode; Solberg, Tore; Storheim, Kjersti; Brox, Jens Ivar; Lønne, Greger; Indrekvam, Kari; Aaen, Jørn; Grundnes, Oliver; Hellum, Christian (Peer reviewed; Journal article, 2019-01-05)Background: Fusion in addition to decompression has become the standard treatment for lumbar spinal stenosis with degenerative spondylolisthesis (DS). The evidence for performing fusion among these patients is conflicting ... -
Follow-up score, change score or percentage change score for determining clinical important outcome following surgery? An observational study from the Norwegian registry for Spine surgery evaluating patient reported outcome measures in lumbar spinal stenosis and lumbar degenerative spondylolisthesis
Austevoll, Ivar Magne; Gjestad, Rolf; Grotle, Margreth; Solberg, Tore; Brox, Jens Ivar; Hermansen, Erland; Rekeland, Frode; Indrekvam, Kari; Storheim, Kjersti; Hellum, Christian (Peer reviewed; Journal article, 2019-01-18)Background: Assessment of outcomes for spinal surgeries is challenging, and an ideal measurement that reflects all aspects of importance for the patients does not exist. Oswestry Disability Index (ODI), EuroQol (EQ-5D) and ... -
Study-protocol for a randomized controlled trial comparing clinical and radiological results after three different posterior decompression techniques for lumbar spinal stenosis: the Spinal Stenosis Trial (SST) (part of the NORDSTEN Study)
Hermansen, Erland; Austevoll, Ivar Magne; Romild, Ulla Kristina; Rekeland, Frode; Solberg, Tore; Storheim, Kjersti; Grundnes, Oliver; Aaen, Jørn; Brox, Jens Ivar; Hellum, Christian; Indrekvam, Kari (Peer reviewed; Journal article, 2017-03-21)Background: There are several posterior decompression techniques for lumbar spinal stenosis (LSS). There is a trend towards performing less invasive surgical procedures, but no multicentre randomized controlled trials have ... -
Surgical treatment and clinical outcomes in Lumbar Degenerative Spondylolisthesis
Austevoll, Ivar Magne (Doctoral thesis, 2020-06-12)Lumbar degenerative spondylolisthesis (DS) is defined as an anterior displacement of one lumbar vertebra relative to the vertebra below due to age-related changes. In clinical practice, DS are most commonly concomitant to ...
