Comparative Study
Traumatic cervical discoligamentous injuries: correlation of magnetic resonance imaging and operative findings.
Retrospective review using prospectively collected data. ⋯ The ability of cervical MRI to detect surgically verified disruptions of the ALL, intervertebral disc, and PLL varied depending on the structure examined. MRI was sensitive but not specific for disc injury, and specific but not sensitive to ALL and PLL disruption. In this series, the comparison of cervical MRI and operative findings indicated that MRI was reliable only when positive for ALL and disc injury, and a reasonably reliable indicator of PLL status only when negative for PLL injury. Additionally, the high false-negative rates for ALL and PLL injury are concerning.

Prospective, longitudinal cohort study ⋯ A threshold of 50% improvement on the ODI may be a valid measure for defining a successful outcome for patients with LBP.

Case report. ⋯ Venous congestive myelopathy due to arteriovenous shunting or unrecognized syrinx are presented as possible etiologies of this patient's spinal cord injury. A preoperative MRI may have helped discern the cause of this patient's spinal cord injury.

A descriptive study (based on skeletal material) was designed to measure sacral anatomic orientation (SAO) in individuals with and without spondylolysis. ⋯ A more horizontally oriented sacrum leads to direct impingement on L5 pars interarticularis by both L4 inferior articular facet superiorly and S1 superior articular facet inferiorly. Repetitive stress due to standing (daily activities) or sitting increases the "pincer effect" on this area, and eventually may lead to incomplete synostosis of the neural arch.

Analysis of spine-related websites available to the general public. ⋯ Our findings suggest that most of the Spine-related patient education materials on professional society and practice-based websites have readability scores that may be too high, making comprehension difficult for a substantial portion of the United States adult population.
