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.

Retrospective and prospective patient surveys and a physician survey using a sample from American Medical Association master file. ⋯ The HD-DQI met several criteria for high-quality patient-reported survey instruments. It can be used to determine the quality of decisions for treatment of herniated disc. More work is needed to examine acceptability for use as part of routine patient care.

Cross-cultural translation and psychometric testing of the functional rating index (FRI). ⋯ The SC-FRI showed excellent reliability and validity in the evaluation of pain and the functional health status of Chinese-speaking patients with LBP. It is simple and easy to use and can be recommended in clinical and research practice in mainland China.

Experimental measurement of bovine caudal annulus fibrosus (AF) biaxial stress-strain states for unloaded motion segments and those loaded in flexion combined with axial compression. ⋯ In flexion combined with compression, the posterior AF stress state is biaxial and is much larger in the axial direction in bovine caudal discs.

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.
