Clinical Trial
Pelvic tilt and truncal inclination: two key radiographic parameters in the setting of adults with spinal deformity.
Prospective radiographic and clinical analysis. ⋯ This study confirms that pelvic position measured via PT correlates with HRQOL in the setting of adult deformity. High values of PT express compensatory pelvic retroversion for sagittal spinal malalignment. This study also demonstrates significant T1-SPI correlation with HRQOL measures and outperforms SVA. This parameter carries the advantage of being an angular measurement which avoids the error inherent in measuring offsets in noncalibrated radiographs.

Analysis of repeated cross-sectional surveys. ⋯ Although the prevalence of neck-shoulder-arm pain and concurrent symptoms decreased in 2006 compared to 2002, it is still too early to conclude that we have reached and passed the peak of the "epidemic" of neck-shoulder-arm pain.

Retrospective study of posterior hemivertebra resection and osteotomies with transpedicular instrumentation in very young children. ⋯ Posterior hemivertebra resection, in case of bar formation with osteotomy of the bar, allows for excellent correction in both the frontal and sagittal planes, with a short segment of fusion. Early surgery in young children prevents the development of severe local deformities and secondary structural curves, thus allowing for normal growth in the unaffected parts of the spine.

A measurement and analysis of the orientation of the lumbar facet joints at the L4-L5 level of different age groups. ⋯ The coronal orientation of the L4-L5 facet joints was negatively correlated to age (r = -0.456, P = 0.000), which could be one of the explanations that the aging people are prone to degenerative spondylolisthesis.

Meta Analysis Comparative Study
A meta-analysis of circumferential fusion versus instrumented posterolateral fusion in the lumbar spine.
A meta-analysis of circumferential fusion versus instrumented posterolateral fusion (PLF) in the lumbar spine. ⋯ Compared with instrumented PLF, circumferential fusion can increase the fusion rate and reduce the reoperation rate, but it can also increase the complication rate and the amount of blood loss. No significant difference was found in the global assessment of clinical outcome about the 2 fusion procedures.
