Objective: Spinal cord stimulation (SCS) is an alternative and invasive treatment option for patients with chronic radicular neuropathic pain. Since December 2004 a newly developed device for SCS with a rechargeable neurostimulator is available. The first clinical experiences and results of seven patients are presented.
Methods: In seven patients (2 female, 5 male) SCS was indicated because of therapeutically refractory chronic radicular neuropathic pain. In five cases a failed back surgery syndrome, in one case each a peripheral arterial vessel disease and a radicular thoracic neuropathic pain was diagnosed. Using local anaesthesia the new electrode with eight contacts was inserted epidurally and a test trial conducted. Pain intensity was documented using the visual analogue scale (VAS).
Results: In all patients it was possible to place the electrode and cover the painful areas with pleasant paraesthesias. During the test trial the patients were able to modulate the stimulation parameters using a newly developed patient programmer. In all patients SCS was able to reduce pain intensity by >50% of the initial VAS and oral pain medication. The rechargeable stimulation device was implanted subcutaneously using general anaesthesia. All patients were able to recharge the devices percutaneously by using a special belt including a magnetic induction coil. No hard-, software or material deficits, nor wound infections were observed.
Conclusions: The newly developed stimulation device Restore™ is a safe and effective system for SCS and allows a better individual setting of the stimulation parameters. The long-term results concerning an battery longevity of 9 years need to be investigated.
