Clinical Trial Summary

The purpose of this prospective post market pilot study is to evaluate the effect of Burst Spinal Cord Stimulation(B-SCS) in the management of chronic discogenic pain in subjects who are refractory to other available treatments. Selected subjects will not be suitable candidates for lumbar spinal surgery and will meet the standard selection process for SCS as routinely utilized in the study centers. Results from this pilot study will inform current clinical practice and future comparative studies in this specific population. Eligible subjects for B-SCS will be asked to participate in this study. If they decide to participate, they will be treated with the Prodigy TM and Proclaim TM (Abbott Laboratories) SCS system and prospectively followed for 12 months following implantation.

Description:

This is a prospective, single-arm, single-center, post-market, pilot study to collect data on back pain relief, subject satisfaction, quality of life, physical functioning and safety. Chronic discogenic pain(CDP) suffering patients will be followed for 12 months with follow-up visits at 3, 6, and 12 months. In line with standard practice the system will be implanted in two stages. The first stage is the Trial Burst spinal cord Neurostimulation (TBNS) phase during which epidural leads are implanted and temporarily tunnelled to an external trial stimulation device. Subjects will then utilize the temporary system for a period in line with usual practice (typically 10-14 days). If, at the end of this TBNS phase a reduction of ≥50% is achieved the device will be permanently implanted (the second stage) and subjects will be followed-up during 12 months. Patients who do not have at least 50% pain relief during TBNS will receive a Trial Tonic Neurostimulator(TTNS) targeting the dorsal root ganglion(DRG). Similarly, these patients will be followed-up during 12 months.
