OBJECTIVE: An association has been suggested between fibromyalgia and cervical myelopathy. If so, treatment of myelopathy could relieve some symptoms of fibromyalgia.
METHODS: Twenty-two fibromyalgia patients with cervical myelopathy (82% female, mean duration of illness 6.1 years +/-4.49) were evaluated. Symptoms included fatigue (100%), cognitive impairment (100%), exertion intolerance (95%), diffuse pain (86%), headache (86%), clumsiness and instability (91%), nonrestorative sleep (82%), nausea (64%), dizziness (59%) and numbness (59%). Neurological signs included hyperreflexia (86%), recruitment of reflexes (46%), impaired tandem walk (41%), positive Romberg sign (37%), spinothalamic sensory level (32%), nystagmus (27%) and appendicular ataxia (23%).
RESULTS: MRI imaging revealed foramen magnum stenosis due to cerebellar tonsillar herniation (n=8), cervical spinal stenosis (n=7) or both (n=7). Surgical decompression of the foramen magnum (n=13), the cervical spinal canal (n=7) or both (n=2) was performed. After a minimum 6-month follow-up, (range: 0.5-2.5 years), 81% of patients reported sustained improvement in the distribution and intensity of pain. Cognitive dysfunction (75%), dizziness (77%), numbness (77%), fatigue (70%), headache (68%), nausea (65%), capacity for exertion (65%) and quality of sleep (50%) also improved. Improved performance on neurological examinations was noted.
CONCLUSION: We conclude that fibromyalgia patients with myelopathy can experience an improvement in symptoms of fibromyalgia following surgical decompression of the cervical spine or foramen magnum. We have developed a database to identify any etiological link between cervical myelopathy and fibromyalgia.
