Association between fatty infiltration in the cervical multifidus and treatment response following cervical interlaminar epidural steroid injection.

Background: Recent attention has been directed towards fatty infiltration in the cervical extensor muscles for predicting clinical outcomes in several cervical disorders. This study aimed to investigate the potential association between fatty infiltration in the cervical multifidus and treatment response following cervical interlaminar epidural steroid injection (CIESI) in patients with cervical radicular pain.

Methods: The data of patients with cervical radicular pain who received CIESIs between March 2021 and June 2022 were reviewed.
