Prior to performing a cervical interlaminar epidural steroid injection (CIESI), knowledge of the depth from lamina to epidural space may assist in preventing cord injury. The current study revealed that while statistically significant correlations do exist between quantitative external body characteristics and depth to cervical epidural space for fluoroscopically guided interlaminar epidural steroid injections at C7-T1, even the most optimal regression models generated from such external body parameters do not permit clinical confidence in predicted depth to epidural space. Moreover, while there was a strong correlation between depth to T1 vertebral lamina and depth to cervical epidural space, depth to lamina predicted depth to epidural space within ± 0.5 cm of the actual depth in only 69% of subjects. The predictive depth to epidural space was as much as 1.6 cm long or 1.7 cm short of the actual fluoroscopically-imaged depth to epidural space. Although the depth to epidural space predicted from the depth to lamina could be applied as a general safety reminder, physicians should consider additional lateral or oblique fluoroscopic views should loss of resistance not yet be obtained after advancing the needle past the predicted depth
