预operative paraspinal muscle parameters (fatty infiltration, CSA ratio, asymmetry) were analyzed in 185 CDA patients to predict postoperative sagittal balance. Results showed CSA ratio at C4/5 and C5/6 levels significantly correlated with postoperative cervical lordosis, SVA, and T1 slope (P<0.001), outperforming FI and ASY%. Structural equation modeling confirmed CSA ratio as the key predictor (P=0.019). Preoperative muscle degeneration, particularly in CSA ratio, may increase sagittal imbalance risk after CDA.
