Inadvertent Intradiscal Contrast Flow During Lumbar Transforaminal Epidural Steroid Injections: A Case Series Examining the Prevalence of Intradiscal Injection as well as Potential Associated Factors and Adverse Events

Abstract

Intradiscal contrast injection is an infrequently reported event during lumbar transforaminal epidural steroid injections. Our data support that the prevalence is very low and there might be an association with ipsilateral foraminal stenosis. Although there is potential for significant adverse complications with intradiscal injection, our data set did not show serious sequelae.
