Comparative Study
The surgical treatment of the lumbar disc prolapse: nucleotomy with additional transpedicular dynamic stabilization versus nucleotomy alone.
Clinical and radiologic study evaluating the outcome after nucleotomy with dynamic stabilization compared with nucleotomy alone. ⋯ The applied dynamic stabilization system is useful to prevent progression of initial degenerative disc disease of lumbar spinal segments after nucleotomy.

Comparative Study
A stronger bicortical sacral pedicle screw fixation through the s1 endplate: an in vitro cyclic loading and pull-out force evaluation.
The insertion torque and pull-out force after cyclic loading of the bicortical sacral pedicle screw through the S1 endplate were tested using human cadaveric specimens. ⋯ In sacral pedicle screw fixation, screw trajectory through the S1 endplate was significantly stronger than screws penetrating the anterior sacral cortex. Insertion torque was a good intraoperative indicator of screw pull-out force after cyclic loading.

Review Comparative Study
The updated cochrane review of bed rest for low back pain and sciatica.
A systematic review within the Cochrane Collaboration Back Review Group. ⋯ For people with acute low back pain, advice to rest in bed is less effective than advice to stay active. For patients with sciatica, there is little or no difference between advice to rest in bed and advice to stay active.

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.
