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.

An analytical cross-sectional computed tomography (CT) study. ⋯ By using an accurate measuring tool, we found an association of the deep and superficial neck muscles' CSA with upper extremities' pain and disability. When performing manual work, a special load is placed on the shoulders and neck muscles. Future research should focus on examining the effectiveness of exercise-type intervention programs to strengthen the deep neck and upper extremities' muscles in order to prevent muscle fatigue.Level of Evidence: 2.

Cohort study. ⋯ DA provides good clinical outcome at 2-year follow-up in patients with LSS and DS with low rate of intra- and postoperative complications and subsequent surgery. Our data supports the evidence that DA is effective and safe for LSS with DS.Level of Evidence: 3.

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.
