Multicenter Study Comparative Study
Spinal deformity correction in Marfan syndrome versus adolescent idiopathic scoliosis: learning from the differences.
Retrospective case control study. ⋯ Patients with Marfan syndrome differ in several ways from those with AIS: they require more levels of surgical correction, more distal fusion, greater correction of sagittal balance, and more reoperations, and they have more intraoperative cerebrospinal fluid leaks and instrumentation-related complications. Knowledge of these differences is important for planning surgery.

Multicentered randomized controlled trial with quality of life and resource use data collected. ⋯ On the basis of this trial, 12 weekly group classes of specialized yoga are likely to be a cost-effective intervention for treating patients with chronic or recurrent low back pain.

A systematic review of the available medical literature from 1980 to 2010 was conducted and combined with expert opinion from a recent survey of experts regarding cervical spine fractures. Using an objective, hierarchical approach, the best available evidence is presented for health-related quality-of-life outcomes for these injuries. ⋯ By overcoming gaps in the literature with consensus expert opinion, our study provides surgeons and others with evidence-based medicine guidelines for patient-centered outcomes after cervical spine injury. This information can be presented to patients to frame expectations of typical outcomes during and after treatment to optimize patient care and quality of life.

A population-based, prospective cohort study. ⋯ Among workers with LBP, early MRI is not associated with better health outcomes and is associated with increased likelihood of disability and its duration. These associations warrant further testing in a randomized controlled trial. Our findings suggest that adherence to evidence-based guidelines is an important factor in ensuring that workers receive the highest quality care for occupational injuries.

Comparison of sodium concentration ([Na]) and proton T2 relaxation time between normal and degenerated discs in a rabbit model. ⋯ Although both [Na] and T2 changes in discs were associated with the disc-punctured rabbits, greater change in [Na] is observed at 12-week poststab compared with T2 change. Because T2 and [Na] reflect different disc properties, performing both imaging under same condition will be helpful in the evaluation of disc degeneration.
