Safety and clinical efficacy.

When applied under the circumstances of minimal patient risk documented in this paper, implanted neuroaugmentive spinal devices are a reasonable means of therapy for selected severe pain problems. With presently developed screening techniques, in 198 patients predominantly suffering from failed back surgery syndrome, a 50% good-to-excellent result was obtained. These figures represent a very significant improvement in the success of treatment for this group of patients when compared to other present modes of therapy. With continued optimization of the use of spinal neuroaugmentive devices, it is likely that clinical success can be further improved in the future.
