Multicenter Study Comparative Study Clinical Trial
A pilot study on the recovery from paresis after lumbar disc herniation.
Although the existence of a motor defect in discogenic sciatica is a sign of severity, the literature does not provide evidence for an immediate requirement for surgery. ⋯ This pilot study showed no difference between surgical or medical management for recovery or improvement in patients with discogenic paresis. These results need confirmation by a randomized study.

Clinical Trial
The evaluation of the surgical management of nerve root compression in patients with low back pain: Part 1: the assessment of outcome.
This was a prospective study investigating the outcome of decompression surgery using validated measures of outcome. ⋯ The visual analogue pain scales, the Oswestry Disability Index, and certain categories of the SF-36 Questionnaire, namely bodily pain and physical and social function, appeared to be the most sensitive outcome measures, with significant improvements occurring at the 6-week and 6-month reviews.

The authors retrospectively determined the prevalence of neck and shoulder symptoms (axial symptoms) after expansive laminoplasty with reattachment of spinous process and extensor musculature in patients with cervical myelopathy. ⋯ Laminoplasty is an appropriate operation for cervical spondylotic myelopathy and did not, in this study, seem to have any significant influence on the development or resolution of axial symptoms.

Randomized Controlled Trial Multicenter Study Clinical Trial
Combined magnetic fields accelerate and increase spine fusion: a double-blind, randomized, placebo controlled study.
The clinical study conducted was a prospective, randomized, double-blind, placebo-controlled trial. ⋯ In conclusion, the adjunctive use of the combined magnetic field device was statistically beneficial in the overall patient population, as has been shown in previous studies of adjunctive bone growth stimulation for spine fusion. For the first time, stratification of fusion success data by gender demonstrated that the female study population responded positively to the adjunctive combined magnetic field treatment, with no statistically significant effect observed in the male study population. Adjunctive use of the combined magnetic field device significantly increased the 9-month success of radiographic spinal fusion and showed an acceleration of the healing process.
