This study reports the clinical outcome of the 3 most commonly used minimally invasive posterior decompression techniques.<p> <p>Objective To compare the effectiveness of 3 minimally invasive posterior decompression techniques for lumbar spinal stenosis. <p>Design, ...
    • Evaluation of the EQ-5D-3L and 5L versions in low back pain patients 

      Garratt, Andrew; Furunes, Håvard; Hellum, Christian; Solberg, Tore; Brox, Jens Ivar; Storheim, Kjersti; Johnsen, Lars Gunnar (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-28)
      <p>Background: The EuroQol EQ-5D is one of the most widely researched and applied patient-reported outcome measures worldwide. The original EQ-5D-3L and more recent EQ-5D-5L include three and five response categories respectively. Evidence from healthy and sick populations shows that the additional two response categories improve measurement properties but there has not been a concurrent comparison ...

      <i>Objective</i> - To assess the reliability of lumbar facet arthropathy evaluation with computed tomography (CT) or magnetic resonance imaging (MRI) in patients with and without lumbar disc prosthesis and to estimate the reliability for individual CT and MRI findings indicating facet arthropathy.<p> <p><i>Methods</i> - Metal-artifact reducing CT and MRI protocols were performed at follow-up of ...
    • Lumbar total disc replacement: predictors for long-term outcome 

      Furunes, Håvard; Hellum, Christian; Brox, Jens Ivar; Rossvoll, Ivar; Espeland, Ansgar; Berg, Linda; Brøgger, Helga Maria; Småstuen, Milada C; Storheim, Kjersti (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-04)
      Purpose: We aimed to identify patient characteristics associated with favourable long-term outcomes after lumbar total disc replacement (TDR). <br>Methods: We analysed a cohort of 82 patients with degenerative disc and chronic low back pain (LBP) who were treatedwith TDR and originally participated in a randomised trial comparing TDR and multidisciplinary rehabilitation. Potential predictors were ...
    • Surgery in Degenerative Spondylolisthesis: Does fusion improve outcome in subgroups? A secondary analysis from a randomized trial (NORDSTEN trial) 

      Hellum, Christian; Rekeland, Frode Gurvin; Småstuen, Milada Cvancarova; Solberg, Tore; Hermansen, Erland; Storheim, Kjersti; Brox, Jens Ivar; Furunes, Håvard; Franssen, Eric; Weber, Clemens; Brisby, Helena; Grundnes, Oliver; Robert Hector Algaard, Knut; Bøker, Tordis; Banitalebi, Hasan; Indrekvam, Kari; Austevoll, Ivar Magne (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-22)
      BACKGROUND CONTEXT: Patients with spinal stenosis and degenerative spondylolisthesis are treated surgically with decompression alone or decompression with fusion. However, there is debate regarding which subgroups of patients may benefit from additional fusion. PURPOSE: To investigate possible treatment effect modifiers and prognostic variables among patients operated for spinal stenosis and ...
