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 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.

Multicenter Study Comparative Study
Comparative study of 2 surgical procedures for osteoporotic delayed vertebral collapse: anterior and posterior combined surgery versus posterior spinal fusion with vertebroplasty.
Retrospective comparative study. ⋯ AP surgery provides stable spinal fixation and reduces implant failure particularly at the thoracolumbar junction because of load bearing of anterior spinal elements. Surgery-related complications in AP surgery were as few in number as with the VP group, and AP surgery is useful for osteoporotic delayed vertebral fracture.

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 case series. ⋯ PET/CT was effective in diagnosing SSI and identifying infection sites despite the presence of spinal instruments. Although further studies with a larger number of patients are required, PET/CT presents a good candidate for detecting early-phase SSI after instrumented spinal surgery.
