Computerized random allocation of patients into one the two groups was done using a random allocation software, Blinding description: Since patients could not see the needle entry point and needle entry points in the two methods used in this study were very close (no more than a few millimeters apart), patients were blind about the group to which they were allocated. Physicians conducting the procedures knew the type of procedure (parasagittal vs midline) they were about to perform on patients and were not blinded to the procedure. Physicians who recorded the pre- and post-intervention data were not aware of the groups to which the patients were allocated. N/A Unilateral cervical radicular pain. Intervention 1: Control group: Cervical epidural steroid and local anesthetic injection with the midline approach. Intervention 2: Intervention group: Cervical epidural steroid and local anesthetic injection with the parasagittal approach.
