Randomized Controlled Trial Multicenter Study Observational Study
Long-term outcomes of lumbar spinal stenosis: eight-year results of the Spine Patient Outcomes Research Trial (SPORT).
Randomized trial with a concurrent observational cohort study. ⋯ Patients with symptomatic spinal stenosis show diminishing benefits of surgery in as-treated analyses of the randomized group between 4 and 8 years, whereas outcomes in the observational group remained stable. Loss to follow-up of patients with worse early outcomes in both treatment groups could lead to overestimates of long-term outcomes but likely not bias treatment effect estimates.

A cross-sectional study to develop a cultural adaptation of the Marathi-neck disability index (NDI) and to investigate its validity and reliability. ⋯ The results suggest that the Marathi version of the NDI that is validated in this study is an easy to comprehend, reliable, and valid instrument for the measurement for the limitation of activities of daily living and pain caused by neck disorders in the Marathi-speaking population.

Retrospective study of a consecutive series of patients with thoracolumbar hyperextension injuries (TLHIs) complicated by diffuse idiopathic skeletal hyperostosis (DISH) presenting to a single institution during a 9-year period. ⋯ To our knowledge, this is the largest series of TLHIs in DISH-altered spines in literature. The study helps to understand controversial findings in literature about morphological properties of TLHIs in DISH-affected spines. Surgeons should be aware of preexisting alterations in traumatized spines and the impact on therapeutic decisions. Because of the "aging population" and implications of metabolic diseases on an "aging spine," the incidence of TLHIs in DISH will probably rise.

A retrospective study. ⋯ Anteverted pelvis appears in almost half of Lenke 5 patients with AIS, especially in who have smaller PI or distal lower end vertebra. The abnormal pelvic sagittal state will be generally corrected by posterior correction surgery except for patients with a PI less than 39° or a lower instrumented vertebra that extends to L5.
