A prospective population-based cohort study performed in South Manchester, United Kingdom. ⋯ Although some specific activities may be hazardous to the back, physical activity outside the workplace does not increase the short-term risk of low back pain overall. Leisure-time physical activity is not a hazard to the back, whereas poor physical health in both genders and heavier weight in women do increase the risk of new low back pain episodes in the short term.

An in vitro study in which a human cadaver model was used to examine the accuracy of two different techniques of percutaneous pedicle screw insertion in the lumbar spine. ⋯ This in vitro study showed that the percutaneous technique of pedicle screw insertion in the lumbar spine is a safe and reliable procedure. Compared with the well-established Magerl technique, the new modified technique did not decrease the misplacement rate significantly, although less pedicle violations were found in the upper lumbar spine.

Randomized Controlled Trial Clinical Trial
Randomized trial comparing interferential therapy with motorized lumbar traction and massage in the management of low back pain in a primary care setting.
A randomized trial designed to compare interferential therapy with motorized lumbar traction and massage management for low back pain in a primary care setting. ⋯ This study shows a progressive fall in Oswestry Disability Index and pain visual analog scale scores in patients with low back pain treated with either-interferential therapy or motorized lumbar traction and massage. There was no difference in the improvement between the two groups at the end of treatment. Although there is evidence from several trials that traction alone is ineffective in the management of low back pain, this study could not exclude some effect from the concomitant massage.

A prospective case-control investigation. ⋯ On discography, thoracic discs with prominent Schmorl's nodes may be intensely painful, even in lifelong asymptomatic individuals, but the pain is unfamiliar or nonconcordant. Thoracic discography may-demonstrate disc pathology not seen on magnetic resonance imaging.

A cross-sectional retrospective study to observe the correlation between postoperation findings shown on magnetic resonance imaging and clinical observations of 56 patients 10 years after laminectomy for lumbar spinal stenosis. ⋯ Patients' perception of improvement had a much stronger correlation with long-term surgical outcome than structural findings seen on postoperation magnetic resonance imaging. Moreover, degenerative findings had a greater effect on patients' walking capacity than stenotic findings.
