33.8% of adult spinal deformity patients have cervical spinal cord compression — 4 things to know

Spine

At 33.8 percent, the prevalence of concurrent cervical spinal cord compression in adult spinal deformity patients is relatively high, and there are several predictive factors, according to a study in Spine.

Four things to know:

1. Of 121 patients with ASD, 41 patients demonstrated significant CSCC on MRI. Intramedullary T2 hyper-intensity, or myelomalacia, was present in 6.6 percent of patients.

2. Of the 41 CSCC patients, 35 were asymptomatic or had difficult-to-detect myelopathy. Significant CSCC was most commonly observed at the C4/5 level.

3. Four patients underwent cervical decompression and fusion prior to thoracolumbar reconstruction.

4. Multivariate regression analysis revealed that older age, increased body mass index and higher pelvic incidence-lumbar lordosis mismatch independently predicted CSCC grade.
