A cross-sectional study. ⋯ SC-BPFS demonstrated outstanding acceptability, internal consistency, reliability, and construct validity, and could be recommended for patients with LBP in Mainland China.Level of Evidence: 3.
-
A retrospective study of consecutive collected data. ⋯ The LIV selected at more cranial to the LTV may be a risk factor for postoperative DA in Lenke Type 1B and 1C curves. Moreover, it was suggested that LIV extension might be considered when the first disc's angulation below the LIV is >3° in intraoperative radiographs.Level of Evidence: 3.
-
A retrospective cohort study. ⋯ Preexisting SAS lesions were associated with aggravation. Meanwhile, biologics may be effective at preventing aggravation.Level of Evidence: 3.

Observational Study
Association Between Paravertebral Muscle Mass and Improvement in Sagittal Imbalance After Decompression Surgery of Lumbar Spinal Stenosis.
Retrospective observational study. ⋯ A larger volume of paravertebral muscles and a lower PI-LL were associated with an improvement in sagittal balance in patients with LSS who underwent decompression surgery.Level of Evidence: 3.
-
Retrospective cohort study of a prospectively collected database. ⋯ Isolated restoration per the Roussouly system was not associated with superior outcomes. Patients who both matched Roussouly type and improved in Schwab modifiers had superior patient-reported outcomes at 2-years. Concurrent consideration of both systems may offer utility in establishing optimal realignment goals.Level of Evidence: 3.
