The integrity of the posterior ligamentous complex (PLC) has been proposed to be an integral aspect in the treatment algorithm for spinal trauma. Magnetic resonance imaging (MRI) has been reported as the ideal tool to determine the integrity of the PLC. The ability to assess disruption of the PLC by reviewers of differing levels of training has not been described. In addition, the MRI sequence most suggestive of injury for each component of the PLC has not been clearly determined. ⋯ The interpretation of traumatic MRI is very sensitive and accurate regardless of years of training of the observer. The attending-level spine surgeon was statistically more specific in the evaluation of injury MRIs. The fluid-weighted STIR sagittal sequences are most useful in determining injury to the SSL, ISL, LF, and cervical facets capsules. Lumbar facet capsules are best evaluated with axial T2 MRI. The evaluation of the PLC on MRI can be accurately and efficiently interpreted by physicians at multiple levels of training, thus providing a key imaging modality in determining stability and need for stabilization.

Randomized Controlled Trial
Supervised exercise, spinal manipulation, and home exercise for chronic low back pain: a randomized clinical trial.
Several conservative therapies have been shown to be beneficial in the treatment of chronic low back pain (CLBP), including different forms of exercise and spinal manipulative therapy (SMT). The efficacy of less time-consuming and less costly self-care interventions, for example, home exercise, remains inconclusive in CLBP populations. ⋯ For CLBP, supervised exercise was significantly better than chiropractic spinal manipulation and home exercise in terms of satisfaction with treatment and trunk muscle endurance and strength. Although the short- and long-term differences between groups in patient-rated pain, disability, improvement, general health status, and medication use consistently favored the supervised exercise group, the differences were relatively small and not statistically significant for these individual outcomes.
