The prevalence of concurrent cervical spinal cord compression in patients with adult spinal deformity is relatively high at 33.8% and, among them, 85.3% were asymptomatic or with myelopathy that is difficult to detect. Even those patients in their 30s had a 37.5% rate of significant cervical cord compression. Preoperative evaluation of cervical MRIs and examinations for signs/symptoms of myelopathy are essential for (1) older patients, (2) patients having increased BMI, and (3) patients with high PI-LL mismatch to avoid progressive myelopathy or cord injury during ASD surgery.
