Multicenter Study Comparative Study
Pediatric spinal injury type and severity are age and mechanism dependent.
Retrospective case review. ⋯ This study has shown that the pattern of spinal injury in children is related to age and also the mechanism of injury. While traffic-related incidents are a leading cause of injury across all age groups, emphasis on fall prevention is needed for younger children. Older children, particularly boys, are sustaining spinal trauma in sporting and recreational activities.

Comparative Study
ProDisc-L total disc replacement: a comparison of 1-level versus 2-level arthroplasty patients with a minimum 2-year follow-up.
This is a retrospective analysis of data that was collected prospectively from 2 concurrent FDA IDE lumbar arthroplasty clinical trials performed at a single center. ⋯ This study was unable to identify a statistically significant difference in outcome between 1- and 2-level ProDisc arthroplasty patients in a cohort from a single center. The equality of clinical effectiveness between 1- and 2-level ProDisc has yet to be determined.

Comparative Study
Disabling low back pain and depressive symptoms in the community-dwelling elderly: a prospective study.
Analytic cross-sectional and cohort study. ⋯ Among community-dwelling elderly persons, depressive symptoms and disabling LBP are widespread. Depressive symptoms predict disabling LBP and vice versa. The set of predictors and their extent of contribution to the prognosis are strikingly similar. Research is warranted to identify possible common pathogenic mechanisms or mediating factors.

Comparative Study
Variability in rates of arthrodesis for patients with thoracolumbar spine fractures with and without associated neurologic injury.
Retrospective cohort study using a large clinical database. ⋯ Hospital teaching status and spine fracture volume affected rates of spine arthrodesis in thoracolumbar fracture patients with and without neurologic injury. Variability in fusion rate for thoracolumbar spine trauma appears to be lower than that reported for elective spine procedures, especially in the presence of a neurologic injury.

Comparative Study
The outcomes of scoliosis surgery in patients with syringomyelia.
A retrospective review of a consecutive case series. ⋯ The lack of thoracic hypokyphosis seen in idiopathic-like curves is a strong indicator of a possible underlying syrinx. Neurosurgical treatment of the syrinx did not improve the scoliosis. Caution should be exercised when choosing fusion levels, and arthrodesis should be planned with the underlying pathology in mind. Scoliosis surgery has proven to be safe in patients with treated syrinx when spinal cord monitoring or wake-up tests are used.
