The correlation of myelographic root sleeve deformity, uncovertebral spondylosis and radiculopathy.

Myelographic root sleeve deformities, uncovertebral spondylosis and myelopathy were correlated in 56 patients. Good correlation between root sleeve deformities and uncovertebral spondylosis was found. However, in some cases with spinal canal stenosis root sleeve deformities were found without corresponding bone changes. The correlation of radiculopathy to root sleeve deformity and uncovertebral spondylosis was 61 and 67%, respectively. Radiologic changes at an adjacent root level were often seen in patients without clinically correlated radiculopathy. The myelographic changes were verified at operation in all the 46 patients operated upon.
