Prospective inception cohort. ⋯ There is evidence for the validity of a single bothersomeness question as a measure of LBP severity. It has the potential to provide a practical standard scheme for classifying patients with LBP in clinical practice. However, further work is needed to clarify its usefulness in a clinical setting.

Analysis of radiographic outcomes following surgical correction of scoliosis. ⋯ In this curve-matched cohort of Lenke Type I curves, PSF with TPS provided superior instrumented correction of main thoracic curves and spontaneous correction of TL/L curves. Perhaps more importantly, PSF/TPS demonstrated improved correction of thoracic torsion and rotation as compared with ASF in terms of RH (P = 0.005) and AVB-R ratio (P= 0.0001), with only one additional spinal segment fused on average.

Prospective cohort study. ⋯ Principles of wide surgical resection, commonly applied in appendicular oncology, can and should be used for the treatment of primary bone tumors of the spine with anticipated acceptable morbidity and satisfactory survival.

In a human cadaveric burst fracture model, the amount of endplate fracture reduction after posterior instrumentation and balloon vertebroplasty was investigated quantitatively. ⋯ Reduction of endplate fractures, both in the center and at the periphery, seems feasible and safe with combined fracture reduction and balloon vertebroplasty. The endplate fracture reduction that was gained by inflation of the bone tamps could not be maintained after deflation.

Case Reports
Cord monitoring changes and segmental vessel ligation in the "at risk" cord during anterior spinal deformity surgery.
Retrospective analysis of all cases of anterior spinal deformity surgery that had intraoperative spinal cord monitoring (somatosensory-evoked potentials, SSEPs). ⋯ Patients with identified cords at risk should undergo spinal cord monitoring (SSEP) if they undergo anterior spinal deformity surgery. Soft clamping of segmental vessels is indicated with cord monitoring to prevent the risk of postoperative neurological sequelae.
