Abstract
The objectives of this study were to assess the effectiveness of cervical spinal cord stimulation in the management of intractable pain syndromes affecting the upper limb and face and to assess the reliability of a specific electrode system in this mobile environment. Forty-one patients, aged 26-76years (median 48) with neuropathic or ischemic pain underwent the cervical epidural implantation of identical dual two-contact paddle (four contacts per system) laminectomy electrodes. Follow-up (from 5months to 11years, 3months; median 4years, 7months) was by multiple consultations carried out by the surgeon and/or in a nurse-led specialist clinic. Overall, 68% obtained sustained pain relief, rated as significant in 51% of the total. Facial pain did not respond. Ischemic syndromes responded well. Lead fracture rate was 15% of the original (11% of the total including replacements) and only 7% (5%) became dislodged.We conclude that the electrode system described provides reliable and sustained cervical cord stimulation. The outcomes are comparable with thoracic cord stimulation for neuropathic and ischemic syndromes.
