Spine

Wedging of apical spinal segments was measured during creation and correction of an experimental scoliosis in a goat model. ⋯ This study demonstrates the ability to create wedge deformities at the apex of an experimental scoliosis in a large animal model and to control the progression of these deformities using anterior thoracic staples.

Comparative Study
Assessment of human disc degeneration and proteoglycan content using T1rho-weighted magnetic resonance imaging.
T1rho relaxation was quantified and correlated with intervertebral disc degeneration and proteoglycan content in cadaveric human lumbar spine tissue. ⋯ Results from this study suggest that T1rho may provide a tool for the diagnosis of early degenerative changes in the disc. T1rho-weighted MRI is a noninvasive technique that may provide higher dynamic range than T2 and does not require a high static field or exogenous contrast agents.

Population-based telephone survey in Missouri. ⋯ Race differences in diagnosis and surgery may help to explain why African Americans, relative to whites, receive lower workers' compensation medical expenditures, disability ratings, and settlement awards.

Evidence-based literature review. ⋯ There are currently no standards regarding the role and timing of decompression in acute SCI. We recommend urgent decompression of bilateral locked facets in a patient with incomplete tetraplegia or in a patient with SCI with neurologic deterioration. Urgent decompression in acute cervical SCI remains a reasonable practice option and can be performed safely. There is emerging evidence that surgery within 24 hours may reduce length of intensive care unit stay and reduce post-injury medical complications.

Comparative Study
Supplementary stabilization with anterior lumbar intervertebral fusion--a radiologic review.
A radiologic assessment of the success of anterior lumbar interbody fusion (ALIF) using thin-section computerized tomography (CT) was performed. ⋯ The addition of pedicle screw fixation at ALIF produces a significant increase in the rate of interbody fusion.
