Controlled Clinical TrialEvolution of bone mineral density after percutaneous kyphoplasty in fresh osteoporotic vertebral body fractures and adjacent vertebrae along with sagittal spine alignment.
Prospective controlled cohort study of 27 adult osteoporotic patients who underwent kyphoplasty for fresh osteoporotic spinal fractures. ⋯ The observed 2-year evolution of vertebral endplate BMD, after kyphoplasty under stable global sagittal spinal balance, might contribute to the pathogenesis of new fractures in adjacent vertebra. However, other studies with control series and longer follow-up are necessary to show if these BMD changes are the result of vertebral augmentation or are merely natural history.

Randomized Controlled TrialReliability of a magnetic resonance imaging-based grading system for cervical intervertebral disc degeneration.
This was a radiographic reliability study of a novel grading system for cervical intervertebral disc degeneration. ⋯ This grading system is comprehensive and easily applicable with sufficient reproducibility. It can be used as a common nomenclature for research and discussions.

Comparative StudyComparison of posterolateral fusion with and without additional posterior lumbar interbody fusion for degenerative lumbar spondylolisthesis.
The surgical approach that should be used for degenerative spondylolisthesis (DS) is a controversial issue. Decompression and posterolateral fusion (PLF) with or without lumbar interbody fusion is widely used. Many studies have compared the outcomes of these 2 approaches, but the appropriate indications for these approaches are still unclear. The authors retrospectively studied the effects of posterior lumbar interbody fusion (PLIF) after PLF for the treatment of DS. ⋯ This study suggests that preoperative segmental instability may be a criterion determining whether an additional PLIF would be beneficial in the treatment of lumbar DS.

Cervical spine motion in manual versus Jackson table turning methods in a cadaveric global instability model.
A study of spine biomechanics in a cadaver model. ⋯ The data suggest that the manual transfer technique produces 2 to 3 times more cervical spine angular motion than the Jackson table method of transfer. The use of a collar provides significant benefit in limiting spine motion that is only observed in axial rotation. Choice of headrest does have a significant effect on the amount of motion allowed during turning, with the Foam Pillow and Prone View generally providing more effective stabilization compared with the Mayfield.

ReviewVertebral artery injuries associated with cervical spine injuries: a review of the literature.
Literature review. ⋯ VAIs can occur in association with cervical spine trauma and have the potential for neurological ischemic events. Screening for and treatment of asymptomatic VAIs may be considered, but it is unclear based on the current literature whether these strategies improve outcomes.
