Clinical study of injection pressure during vertebroplasty. ⋯ High injection pressures approaching 20 atmospheres are reached during conventional vertebroplasty. Widening the syringe tip diameter did not significantly change injection pressures, whereas elapsed time did. Further research is needed to improve injection equipment and materials for vertebroplasty.

Cross-sectional analysis. ⋯ A small but significant number of injured workers do not seek care for their back pain. Medical physicians treat all but a small fraction of the workers who receive care. The decision to seek care and the choice of providers is associated with injury severity, occupation, and employer actions.

Comparative Study
Non-fusion surgery for degenerative spondylolisthesis using artificial ligament stabilization: surgical indication and clinical results.
A retrospective study. ⋯ Artificial ligament stabilization did not improve the vertebral slip but maintained lordosis and preserved segmental motion in 80% of patients. This procedure is an effective alternative to spinal arthrodesis in the treatment of symptomatic degenerative spondylolisthesis (Grade I) with minimal disc space narrowing and coronal facet tropism.

Comparative Study
Validation of the Korean version of the oswestry disability index.
Validation of a translated, culturally adapted questionnaire. ⋯ The results of this study indicate that the Korean version of the ODI is a reliable and valid instrument for the measurement of disability in Korean patients with lower back problems. The authors recommend this Korean version of the ODI for use in future clinical studies in Korea.

Cross-sectional surveys of health-related quality of life (HRQOL) in patients with low back pain at ambulatory clinics plus 8 weeks of follow-up. ⋯ The HRQOL of patients with low back pain depended on functional status and psychological factors more than simple physical impairment. Future intervention may need to put more emphasis on improving functional status and psychological stress for these patients.
