Multicenter Study
How Decompression Surgery Improves the Lower Back Pain in Patient With Lumbar Degenerative Stenosis: A Propensity-score-matched Analysis.
Multicenter retrospective case series of patients treated surgically for lumbar spinal stenosis (LSS). ⋯ Decompression surgery for LSS significantly improved LBP. Sex and baseline LBP were risk factors for residual LBP. However, when males and females were matched by confounders, no difference was found in the LBP after surgery. Patients with severe baseline LBP may need further evaluation for their mental status because these patients are likely to have mental problems that potentially contribute to persistent LBP.Level of Evidence: 4.

A case-control study. ⋯ Paraspinal approach is a good manner to protect deep extensor muscles; the two modified LPs have similar effects on clinical outcomes.Level of Evidence: 3.

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.

Prospective comparative study. ⋯ Q-CT provides more precise estimation of cancellous bone mineral density than DXA. With the reliance on DXA for spinal BMD estimation being questionable, new standards have to be established for spinal osteoporosis evaluation. Q-CT can be a better alternative to replace DXA as the gold standard for the evaluation of spinal osteoporosis.Level of Evidence: 2.
