SCCM is measured by the spinal cord occupation ratio (SCOR). Patients were categorized into SCCM (SCOR \u2265 0.7) and no-SCCM (SCOR &lt; 0.7) groups. PROMs, including the Neck Disability Index (NDI), Visual Analog Scale for Neck (VAS-Neck), Arm Pain (VAS-Arm), and GRC, were assessed preoperatively and postoperatively. MCID achievement was analyzed at early (6-12 weeks) and late (6 months\u20132 years) follow-ups. Statistical tests and logistic regression identified predictors of MCID failure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Ninety-eight patients (55 SCCM, 43 no-SCCM) were included. Both groups demonstrated significant postoperative improvements in PROMs. Early postoperative MCID rates for NDI, VAS-Neck, and VAS-Arm were 61.4%, 61.4%, and 56.8%, respectively, with no significant differences between groups. Similarly, late postoperative MCID rates and GRC outcomes showed no significant differences. SCCM was not a significant predictor of MCID failure, though male sex was associated with higher odds of MCID failure in NDI (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n
