v4.1 Fusion X
CSM is progressive spinal cord dysfunction due to degenerative stenosis (disc osteophyte complex, ligamentum flavum hypertrophy, OPLL). Symptoms: hand clumsiness, gait imbalance, Lhermitte sign; UMN signs below level (Hoffmann, Babinski) with possible segmental LMN at level. MRI is diagnostic; assess sagittal alignment, number of compressed levels, and canal diameter. Surgery for moderate–severe or progressive CSM: anterior (ACDF/corpectomy) vs posterior (laminoplasty/laminectomy + fusion) based on alignment and levels. Prognostic factors: shorter symptom duration, younger age, no signal change on T2 MRI.
