-
Retrospective multicenter study. ⋯ The intervertebral level of stenosis did not affect surgical outcomes after posterior decompression for CSM.Level of Evidence: 3.

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.

Observational Study
A Prospective, 3-year Longitudinal Study of Modic Changes of the Lumbar Spine in a Population-based Cohort: The Wakayama Spine Study.
Large-scale, prospective, population-based, longitudinal observational study. ⋯ This study revealed a high incidence of MCs at the upper lumbar levels and transformation at the lower lumbar levels. Reverse transformation of MCs occurs but are rare.Level of Evidence: 2.
-
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.
-
Prospective cohort study. ⋯ Compared with MI-TLIF, OLIF showed similar results in terms of patient-reported outcomes, restoration of SLA and fusion rate, and superior results with respect to restoration of DH and LLA, operation time, estimated blood loss, length of hospital stay, and serum CK levels (1 day postoperatively). Even though the complication rate of OLIF is higher than that of MI-TLIF, it does not bring persistent and substantial damage to the patients.Level of Evidence: 3.
