Myoclonus is defined as the involuntary muscle contractions that occur suddenly, irregularly, and asymmetrically. It is classified into various types based on the anatomical site of origin or etiology. Among them, spinal myoclonus refers to movement disorders originating from the spinal cord, which can be caused by conditions such as tumors, infections, degenerative diseases, trauma, or spinal compression. Although rare, neuraxial anesthesia, including spinal and epidural anesthesia, is known to induce spinal myoclonus. Cervical epidural steroid injection is a commonly used conservative treatment for radicular pain originating from the cervical spine. The incidence of complications following epidural steroid injections is reported to be relatively low. However, there have been rare cases reported of segmental spinal myoclonus occurring after epidural steroid injections. Here, we present a case of segmental spinal myoclonus that occurred after cervical epidural steroid injection in a patient with cervical disc herniation. We aim to share this case and discuss the management strategies when such complications arise.
