Conditions

Cervical Radiculopathy

Brief summary

Cervical epidural steroid injections are an accepted treatment modality for radicular pain secondary to disc pathology. With the developing ultrasound technology, ultrasound guided cervical selective nerve root block has been successfully used in the treatment of cervical radiculopathy. We aimed to compare the efficacy of cervical interlaminar epidural injections and cervical selective nerve root block.
