A 20-year-old wheelchair athlete with a history of caudal regression syndrome and cervical canal stenosis developed spinal segmental myoclonus after undergoing routine intubation for an elective surgical procedure. The patient experienced twitching movements in his pectoral muscles, left deltoid, and biceps, which were consistent with myoclonus due to his cervical myelopathy. The myoclonus was initially managed with clonazepam, and the patient underwent cord decompression and fusion surgery, which resolved his symptoms.
Clinicians should consider cervical myelopathy as a potential cause of segmental myoclonus, especially in patients with pre-existing spinal conditions or a history of recent trauma or manipulation.
While medications like clonazepam can help manage myoclonus symptoms, cord decompression surgery may be necessary to address the underlying cause and prevent further neurological complications.
Patients with congenital spinal stenosis or other spinal abnormalities may be at increased risk for myelopathy following even minor trauma or routine procedures, such as intubation, and should be monitored closely.
