Comparative Study
Comparison of patient and surgeon perceptions of adverse events after adult spinal deformity surgery.
Survey based on complication scenarios. ⋯ There was substantial variation in how both surgeons and patients perceived impacts of various adverse events after spine surgery. Patients generally perceived the impact of adverse events to be greater than surgeons. Patient-centered descriptions of adverse events would provide a more complete description of surgical outcomes.

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 review. ⋯ In the elderly patient, PSO and VCR can achieve significant restoration of sagittal and coronal balance and significant improvement in quality of life. However, both techniques can lead to serious complications and should be selectively used.
-
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.

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.
