Randomized Controlled Trial Multicenter Study Comparative Study
Qigong and exercise therapy in patients with long-term neck pain: a prospective randomized trial.
A randomized, controlled, multicenter trial: 1-year follow-up. ⋯ These results indicate that treatments including supervised qigong or exercise therapy resulting in reduced pain and disability can be recommended for persons with long-term nonspecific neck pain.

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.

Multicenter Study
Diabetes and early postoperative outcomes following lumbar fusion.
Retrospective cohort study using data from the Nationwide Inpatient Sample administrative data from 1988 through 2003. ⋯ This nationally representative study of inpatients in the United States provides evidence that diabetes is associated with increased risk for postoperative complications, nonroutine discharge, increased total hospital charges, and length of stay following lumbar fusion. Prospective studies to determine causality as well as the potential impact of diabetes control on these variables have not yet been done.

Multicenter Study Comparative Study
Surgical revision rates of hooks versus hybrid versus screws versus combined anteroposterior spinal fusion for adolescent idiopathic scoliosis.
Multi-institution retrospective review. ⋯ All pedicle screw and anteroposterior constructs have a lower surgical revision rate when compared with hook and hybrid constructs. The hidden patient and financial costs of these findings should be considered when evaluating overall instrumentation efficacy.
