Retrospective analysis of prospectively collected registry data. ⋯ A 30% reduction from baseline is a valid method for determining MCID in disability and pain for patients undergoing cervical spine surgery.Level of Evidence: 3.
-
Retrospective observational cohort study. ⋯ We propose a classification for the severity of ATCSCI based on DTI and DTT that may explain why some patients with ASIA A recover, whereas others do not.Level of Evidence: 4.

Comparative Study
Comparison of Freshly Isolated Adipose Tissue-derived Stromal Vascular Fraction and Bone Marrow Cells in a Posterolateral Lumbar Spinal Fusion Model.
Rat posterolateral lumbar fusion model. ⋯ In a rat model, A-SVF cells yielded a comparable fusion mass volume and radiographic rate of fusion to BMCs when combined with a clinical-grade bone graft substitute. These results suggest the feasibility of using freshly isolated A-SVF cells in spinal fusion procedures.Level of Evidence: N/A.

Comparative Study
Cervical Alignment Following Posterior Cervical Fusion Surgery: Cervical Pedicle Screw Versus Lateral Mass Screw Fixation.
Retrospective comparative study. ⋯ The present study is the first radiologic comparison of LMS and CPS fixation after posterior-only fusion surgery. CPS resulted in more reliable and well-preserved SA correction, whereas CL and SVA did not differ between the two groups over time due to loss of correction.Level of Evidence: 4.
