Objective: Spinal cord stimulation (SCS) is an established treatment of chronic pain of the legs and lower back. However, dominant back pain still remains a challenge for traditional spinal cord stimulation. This prospective study presents our 12 month experience with a minimally invasive percutaneously implantable, paraesthesia free, high frequency spinal cord stimulation.
Method: Data was collected prospectively. Patients were implanted percutaneously with two leads between segments T8–T11 and in midline position. All implantations have been performed under general anaesthesia. Patients underwent a seven days trial stimulation. Upon successful trial an implantable pulse generator (IPG, Nevro Senza) was implanted.
Results: 42 FBSS patients with dominant back and leg pain underwent a trial phase with high frequency spinal cord stimulation. 39 patients had a successful trial (mean duration 7 days). After 12 months the mean back pain decreased from VAS 9.2±0.5 to 2.7±1.9 and the leg pain from 5.3±0.7 to 2.6±1.4. The Oswestry Disability Index decreased from 51±2 to 31±2. No serious complications were observed.
Conclusions: Our data shows high frequency, thus paraesthesia free stimulation, to be effective and safe. Placement is done under general anaesthesia. The approach offers a novel elegant procedure for back dominant FBSS patients.
