A retrospective comparative study. ⋯ Fifty-six percent of patients with clinically mild CSM with ISI had not deteriorated or undergone surgery at 10 years. Large range of motion, segmental kyphosis, and instability at the narrowest canal were considered to be adverse prognostic factors.
-
Systematic review. ⋯ We recommend that the surgeon make every effort to keep the plate as far away from the adjacent disc as possible. Strength of Statement: Strong.

Review Meta Analysis Comparative Study
Kinematics of the cervical adjacent segments after disc arthroplasty compared with anterior discectomy and fusion: a systematic review and meta-analysis.
Systematic review and meta-analysis. ⋯ Patients can be advised that single-level arthroplasty and ACDF result in clinically similar kinematic changes at short-term follow-up. Strength of Statement: Strong.
-
Consecutive case series and literature review. ⋯ The present findings suggest that the frequency of an abnormal VA at the extra- and intraosseous regions is increased when patients have AAS and CSA at the CVJ. Using preoperative 3D CTA, we can precisely identify anomalous VAs and thereby reduce the risk of their intraoperative injury.
-
Systematic review. ⋯ ASP may occur at a higher rate than natural spinal degeneration and suggests that another factor (such as biomechanical effect of fusion) may accelerate pathologic changes. Strength of Statement: Weak.
