Multicenter Study
Assessment of Adult Spinal Deformity Complication Timing and Impact on Two-Year Outcomes Using a Comprehensive Adult Spinal Deformity Classification System.
Retrospective review of prospectively collected multicenter registry data. ⋯ Surgeons should recognize that long-term complications have a substantial negative impact on HRQoL, and should carefully monitor for implant-related and radiographic complications over long-term follow-up.Level of Evidence: 4.
-
Retrospective cohort study. ⋯ Among ASD patients undergoing long-segment primary fusion to the pelvis, the risk of PJF was lower among patients with less than 1.8 screws per level. This finding may be related to construct rigidity. Residual confounding by other patient and surgeon-specific characteristics may exist. Further biomechanical and clinical studies exploring this relationship are warranted.Level of Evidence: 3.

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.
