Comparative Study
Long-term outcome of laminoplasty for cervical myelopathy due to disc herniation: a comparative study of laminoplasty and anterior spinal fusion.
A retrospective study was conducted. ⋯ Because the 2 procedures provided the same neurologic improvement, the risks of bone graft complication with ASF must be weighed against the risks of chronic neck pain associated with laminoplasty for determining the best technique. Therefore, because our present surgical strategy for cervical myelopathy due to disc herniation, laminoplasty is the procedure of choice except for a patient with single level disc herniation without developmental canal stenosis, who is considered to be a good candidate for ASF.

Comparative Study
Standardized provocation of lumbar spine mobility: three methods compared by radiostereometric analysis.
By radiostereometric analysis (RSA), the intervertebral mobility was measured for the 3 most distal lumbar disc levels in 12 patients at 3 types of standardized provocation: changing body position from supine to standing, supine to standing with load, and supine to sitting. ⋯ The intervertebral mobility response provided in the lumbar spine when changing position from supine to sitting is more pronounced than both to standing and to standing with a 20 kg load. By the supine to sitting provocation, mean lumbar mobility is increased, and mobility can be revealed in some cases being stable in the other 2 situations. Combined with RSA, the method brings a refined possibility for studying lumbar spine kinematics.

Cross-sectional cohort study of a general population. ⋯ In children, degenerative disc findings are relatively common, and some are associated with LBP. There appears to be a gender difference. Disc protrusions, endplate changes, and anterolisthesis in the lumbar spine were strongly associated with seeking care for LBP.

An original study was performed evaluating the information presented on existing web sites for the topic of lumbar disc herniation. ⋯ The quality of internet information on lumbar disc herniation is variable. Less than 10% of relevant web sites were determined to be of high-quality. The vast majority of sites were of poor informational value and more than one-third sought secondary commercialgain. The rank list of high quality sites generated from ourinformational quality score should prove useful to patients seeking information on the internet pertaining to lumbar disc herniation.

Observational cohort study with computerized tomography (CT) analysis of in vivo pedicle screw placement. ⋯ The clinical pedicle breach rate in this study is comparable to those reported using conventional techniques with or without fluoroscopic assistance. FluoroNav appears to be a safe adjunct for the placement of thoracic and LS pedicle screws.
