The objective of this study is to present the paid expenditures and productivity costs of disability pensions (DP) due to spinal disorders (SD) in Finland during 1990-2010. ⋯ Despite a significant decrease in DP-associated expenditures due to SDs after 1993, the annual expenditures have stayed on a high level in Finland.

Meta Analysis Comparative Study
A meta-analysis of endoscopic discectomy versus open discectomy for symptomatic lumbar disk herniation.
The purpose of this study was to systematically compare the effectiveness and safety of endoscopic discectomy (ED) with open discectomy (OD) for the treatment of symptomatic lumbar disc herniation (LDH). ⋯ From the existing outcomes, ED surgery could be viewed as a sufficient and safe supplementation and alternative to standard open discectomy. The cost-effectiveness analyses still remain unproved from the existing data. More independent high-quality RCTs using sufficiently large sample sizes with cost-effectiveness analyses are needed.

Multicenter Study Clinical Trial
Core Outcome Measure Index for low back patients: do we miss anxiety and depression?
The Core Outcome Measure Index (COMI) is a multidimensional questionnaire that investigates five dimensions in low back pain (LBP) patients, but does not address the psychological dimension. As the biopsychosocial perspective is recognized as important to capture the entire clinical picture of these patients, this multicenter prospective cohort study was designed to investigate the psychometric properties of a modified version of the COMI (COMIAD) which included 2 additional items, exploring anxiety and depression, respectively. ⋯ The questions exploring anxiety and depression have good intrinsic and psychometric capacities (i.e., no floor or ceiling effects and high correlations with full-length scales) and did not significantly modify the psychometrics of the original COMI questionnaire. The COMIAD offers the possibility to include the psychological dimension in the multidimensional evaluation without significantly affecting questionnaire length.
