Predictors of Clinical Response After Interlaminar Cervical Epidural Steroid Injection for Cervical Radiculopathy

Observational NCT07535476 Kind: OBSERVATIONAL Apr 17, 2026

Abstract

Cervical epidural steroid injection is a commonly used treatment option for patients with cervical radicular pain who do not improve adequately with conservative treatment. Cervical radicular pain typically radiates from the neck to the shoulder, arm, or hand and may be accompanied by numbness, weakness or changes in reflexes. The most common causes are cervical disc herniation and cervical spondylosis. By reducing inflammation around the affected nerve root, epidural steroid injection may help relieve pain and improve function. Among available techniques, the interlaminar approach is frequently preferred in the cervical region because of its technical feasibility and safety profile.

Although interlaminar cervical epidural steroid injection is widely used, treatment response varies among patients, and not all individuals experience the same degree of benefit. Identifying the factors associated with better or poorer clinical response may help improve patient selection and reduce unnecessary procedures.

This retrospective cohort study aims to evaluate clinical outcomes after interlaminar cervical epidural steroid injection in patients with cervical radiculopathy and to investigate demographic, clinical, and procedure-related variables which may predict treatment response. By analyzing pain scores before and after the procedure, this study seeks to better define the predictors of clinical outcome following this intervention.
