Objective: Spinal cord stimulation (SCS) is an established method for treatment of chronic pain. Up to 15% of patientens implanted with a conventional SCS system lack sufficient pain reduction. The aim of this study is to examine wether failed SCS patient profit from high frequency stimulation.

Method: Data was collected prospectively. FBSS patients with back and leg pain who failed conventional SCS were eligable to participated in the study. The already implanted leads (St. Jude S8) were left in place and connected via a specially designed connection system to the lead extension which was externalised and connected to a high frequency trial stimulator (both Nevro). After a successful trial an implantable pulse generator (IPG, Nevro Senza) was implanted.

Results: 8 patients were included into the study. All patients had a successfull trial phase (mean duration 6 days). Mean back pain decreased significantly (p<0.05) from VAS 8.6 ± 0.5 to 2.5 ± 1.9 and mean leg pain decreased significantly (p<0.05) from VAS 7.3 ± 0.7 to 1.6 ± 1.4 during the trial phase. 3 months after the IPG implantation, the back and leg pain scores remained stable at 2.3 ± 0.7 and 1.3 ± 1.5 respectively. There were no complications.

Conclusions: This study shows high frequency spinal cord stimulation to be effective and safe. It can be used as a rescue therapy for FBSS patients not responding to conventional tonic spinal cord stimulation.
