Review Case Reports
Subaxial positional vertebral artery occlusion corrected by decompression and fusion.
A rare case of subaxial vertebral artery (VA) positional occlusion is reviewed and treatment methods discussed. ⋯ This report demonstrates the condition in the subaxial spine and describes successful treatment by fusion of the affected level combined with decompression of the foramen transversarium-a combination of previously described therapies.

Comparative Study
Degeneration of sacroiliac joint after instrumented lumbar or lumbosacral fusion: a prospective cohort study over five-year follow-up.
A prospective cohort study. ⋯ Instrumented posterolateral lumbar/lumbosacral fusion can be a cause of SIJ degeneration. SIJ degeneration develops more often in patients undergoing lumbosacral fusion regardless of the number of fusion segments.

Comparative Study Clinical Trial
Calcium-phosphate and polymethylmethacrylate cement in long-term outcome after kyphoplasty of painful osteoporotic vertebral fractures.
A comparative prospective trial evaluating 3-year outcome. ⋯ CaP cement, e.g., Calcibon, is as effective and safe as conventional PMMA-cement with regard to immediate and sustained pain reduction and improvement of mobility after kyphoplasty of patients with painful osteoporotic vertebral fractures. CaP cement has the potential of being resorbed and replaced by newly formed bone tissue; thus, it seems to be a promising alternative for PMMA also in younger patients with painful vertebral fractures.

Comparative Study
Association of a single nucleotide polymorphism in the insulin-like growth factor-1 receptor gene with spinal disc degeneration in postmenopausal Japanese women.
An association study investigating the genetic etiology for spinal disc degeneration. ⋯ We suggest that a genetic variation at the IGF1R gene locus is associated with spinal disc degeneration, in line with the involvement of the IGF1R gene in the cartilage metabolism.

Comparative Study
The influence of pain-related fear on peak muscle activity and force generation during maximal isometric trunk exertions.
A cross-sectional study of peak activation of trunk muscles in 20 participants with chronic low back pain. ⋯ Pain-related fear is associated with increased disability, in theory, because of avoidance behavior and disuse. Our data suggest that participants high in pain-related fear specifically avoid activation of the abdominal muscles during maximal isometric trunk exertions.
