Retrospective study. ⋯ Posterior vertebral column resection is an effective alternative for moderate to severe deformities with limited flexibility. However, it is a technically demanding and exhausting procedure with possible risks for major complications.

A retrospective study of 19 consecutive cases (1991-2001) where 91 thoracic and lumbar pedicle screws were used in the treatment of various pediatric spinal disorders in 1- and 2-year-old children. ⋯ The results suggest that pedicle screw fixation can be performed safely in 1- and 2-year-old children without negative effects on vertebral growth. In various pediatric spinal disorders, transpedicular screw fixation is the only procedure that provides a secure anchorage in short-segment instrumentation.

Experimental investigation of the electrical conductivity of normal and trypsin-treated lumbar anulus fibrosis specimens. ⋯ Measured electrical conductivity was sensitive to tissue porosity, but not to fixed charged density for anulus fibrosis specimens in phosphate-buffered saline.

Randomized Controlled Trial Comparative Study Clinical Trial
Two-year follow-up of a randomized clinical trial of spinal manipulation and two types of exercise for patients with chronic neck pain.
Randomized clinical trial. ⋯ The results of this study demonstrate an advantage of spinal manipulation combined with low-tech rehabilitative exercise and MedX rehabilitative exercise versus spinal manipulation alone over two years and are similar in magnitude to those observed after one-year follow-up. These results suggest that treatments including supervised rehabilitative exercise should be considered for chronic neck pain sufferers. Further studies are needed to examine the cost effectiveness of these therapies and how spinal manipulation compares to no treatment or minimal intervention.

Review Case Reports
Transient blindness after lumbar epidural steroid injection: a case report and literature review.
A case report of transient blindness after lumbar epidural steroids is presented. ⋯ Transient blindness is a rare complication of lumbar epidural injection. The pathophysiology and prevention of this rare entity is reviewed.
