Retrospective radiographic review. ⋯ CBT and DVR can broaden the current curve criteria of MTCL curves for STF to have more MTCL curves treatable with STF and optimize instrumented thoracic and spontaneous lumbar correction. A more effective surgical technique can not only improve instrumented thoracic and spontaneous lumbar correction but also can broaden the MTCL curve criteria for STF to have more MTCL curves treatable with STF.

Review Meta Analysis Comparative Study
Surgery versus conservative treatment for symptomatic lumbar spinal stenosis: a systematic review of randomized controlled trials.
Systematic review. ⋯ In patients with symptomatic LSS, the implantation of a specific type of device or decompressive surgery, with or without fusion, is more effective than continued conservative treatment when the latter has failed for 3 to 6 months.

Retrospective study. ⋯ Comparable bone density exists among adult scoliosis patients with no correlation between BMD and curve magnitude, fusion and complication rates. The difference in BMD of the hip and of spine cannot be fully explained in the review. These results will guide in surgical planning, patient selection on the treatment options.

In vitro cadaveric study of cervical spinal cord intramedullary pressure (IMP) in kyphotic deformity. ⋯ Cervical lordosis and kyphosis less than +7.5° resulted in no meaningful increase in IMP. Minor cervical kyphosis measuring +7.5° to +21° resulted in 2 to 5 mm Hg increases in IMP. As the cervical kyphotic deformity exceeded +21°, IMP increased significantly. ΔIMP with spinal alignment may help to explain the wide range of "normal" cervical neutral upright sagittal alignment in studies of asymptomatic individuals and may help further define cervical kyphotic deformity.

Comparative Study
An adapted Chinese version of neck pain and disability scale: validity and reliability.
This is a validation study to evaluate validity and reliability of a translated and culturally adapted Neck Pain and Disability Scale (NPAD). ⋯ The authors report the validation of a Chinese version of NPAD for use in China, which is culturally relevant, reliable, repeatable, and psychometrically sound.
