Background and purpose: Over the last decades, many countries have shown increased surgery rates for lumbar spinal stenosis (LSS), but little information is available from Denmark. We describe the development…
Study design: Retrospective cohort study. Objective: The aim of this study was to determine the incidence of and risk factors for persistent opioid use after elective cervical and lumbar spine…
Study design: Retrospective Cohort Study. Objectives: Few previous studies have examined the relationship between preoperative disability and patient outcomes after complex adult spinal deformity surgery. In this study, we hypothesized…
Study design: Retrospective Cohort Study. Objectives: To investigate and compare the prevalence of low bone mineral density (BMD) and abnormal laboratory bone metabolism parameters in patients undergoing elective primary discectomy,…
Background: Erector spinae plane block, a novel ultrasound-guided fascial plane block, has become popular for perioperative pain management. This randomized controlled trial tested the hypothesis that preoperative bilateral erector spinae…
Objective: There are several techniques for lumbar interbody fusion, and implant failure following lumbar interbody fusion can be troublesome. This study aimed to compare the stress in posterior implant and…
Study design: Systematic Review. Objective: To collect and group definitions of segmental instability, reported in surgical studies of patients with lumbar spinal stenosis (LSS) and/or lumbar degenerative spondylolisthesis (LDS). To…
Objective: The purpose of this study was to analyze whether the type of preoperative pain affects the improvement in postoperative pain intensity in patients with a lumbar degenerative disease (LDD).…
Purpose: To evaluate the biomechanics of a novel fusion strategy (hybrid internal fixation+horizontal cage position) in minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF). Methods: MIS-TLIF finite element models for three…
Objectives: To compare the clinical efficacy of a new retractor-assisted Wiltse transforaminal lumbar interbody fusion (TLIF), minimally invasive TLIF (MIS-TLIF), and traditional posterior lumbar interbody fusion (PLIF) in treating single-level…
