Comparative Study
Comparison of the EuroQOL-5D with the Oswestry Disability Index, back and leg pain scores in patients with degenerative lumbar spine pathology.
Cross-sectional study. ⋯ The EQ-5D correlated well with established spine outcome measures, including ODI, and back and leg pain scores. EQ-5D correlated best with ODI scores. Correlation with back pain was stronger than leg pain, but all correlations were relatively strong. The EQ-5D can serve spine surgeons as an effective measure of clinical outcome and health utility for economic analysis.

Retrospective consecutive case series. ⋯ "Worsening" and "symptoms combination" are progression characteristics of SDAVF. Patients should undergo spinal magnetic resonance imaging when they are first suspected to have SDAVF. Magnetic resonance angiography and computed tomography angiography as noninvasive angiography are helpful for diagnosis.

Case control study. ⋯ Cervical motion segment contributions to flexion-extension change significantly during the flexion-extension motion. The largest change in percent contribution to motion, relative to controls, occurs at the C6-C7 motion segment, over the entire ROM, suggesting a potential mechanical mechanism for the clinical observation of increased incidence of adjacent segment degeneration at C6-C7 rather than at C4-C5 after C5-C6 arthrodesis.

Extensive validation of the pain disability index in 3 groups of patients with musculoskeletal pain.
A cross-sectional study design was performed. ⋯ The PDI-Dutch language version is internally consistent as a 1-factor structure, and test-retest reliable. Missing items seem high in sexual and professional items. Using the PDI as a 2-factor questionnaire has no additional value and is unreliable.
