Comparative Study
Hybrid constructs for tridimensional correction of the thoracic spine in adolescent idiopathic scoliosis: a comparative analysis of universal clamps versus hooks.
Retrospective study of prospectively collected data. ⋯ Although both of these hybrid constructs efficaciously corrected the coronal and axial deformities in AIS, the results of the UC technique were superior to those achieved with hooks in all 3 planes, especially the sagittal plane. Moreover, the UC technique is straightforward and safe, reducing both operative duration and blood loss.

Comparative Study
Effects of perioperative blood product use on surgical site infection following thoracic and lumbar spinal surgery.
Retrospective case-control review. ⋯ Our findings support current theories that blood transfusions may have modulatory effects on the immune system of the recipients. Our specific study in spine patients may contribute to the expanding literature on allogeneic blood transfusions and the risk of nosocomial infections and encourage surgeons to favor a more restrictive policy with regard to transfusions.

Randomized Controlled Trial Comparative Study
Degenerative spondylolisthesis versus spinal stenosis: does a slip matter? Comparison of baseline characteristics and outcomes (SPORT).
As-treated analysis of the Spine Patient Outcomes Research Trial. ⋯ Overall, DS and SPS patients had similar baseline characteristics. However, DS patients improved more with surgery than SPS patients. Future studies should probably not combine these heterogeneous patient populations.

In vivo study on cervical spine motion. ⋯ The current study demonstrated that for the comparison of functional outcome after different therapies of C2 fractures clinical measurements do not serve for reliable data on total neck rotation and particularly atlantoaxial rotation and the percentage of C1-C2 rotation of total neck rotation. The use of dynamic CT-scans in the analysis of functional outcome after C2 fractures is strongly recommended.

Comparative Study
The association between Scoliosis Research Society-22 scores and scoliosis severity changes at a clinically relevant threshold.
Cross-sectional correlation study. ⋯ Deterioration in SRS-22 scores is mildly associated with increases in the severity of the internal deformity. HRQOL is stable until the curve reaches a maximal Cobb angle threshold at approximately 45 degrees where HRQOL declines linearly with increasing internal deformity. The association between HRQOL and scoliosis severity is low, but is better explained by segmented rather than linear models.
