Deep Brain Stimulation of the Subgenual Cingulate Cortex for the Treatment of Medically Refractory Chronic Low Back Pain
University of California, Los Angeles
Summary
The purpose of this study is to evaluate the feasibility and preliminary efficacy of deep brain stimulation of the subgenual cingulate cortex for the treatment of chronic medically-refractory low back pain using a randomized double-blind crossover design.
Description
Chronic low back pain (CLBP) is one of the most ubiquitous and intractable problems in medicine and a significant source of patient suffering and disability, leading to opioid misuse and addiction. Previous neuromodulatory therapies for CLBP have focused primarily on spinal etiologies and intra-spinal mechanisms of pain transmission. However, existing pharmacological and neuromodulatory therapies have not been successful in treating CLBP. This project aims to address critical gaps and the unmet therapeutic needs of CLBP patients by using the Abbott Infinity DBS System; a next generation DBS de…

Inclusion Criteria: * Pain secondary to failed back surgery syndrome (FBSS) as defined by persistent low back pain despite prior surgical interventions. * Self-reported average back pain intensity of greater than 8 out of 10 on the Visual Analog Scale (VAS) documented over greater than 2 years. * Failure to achieve at least 50% pain relief from a trial of spinal cord stimulation (SCS) or less than 50% pain relief after 3 months of SCS therapy or patient refuses/rejects SCS trial * Failure to achieve at least 50% pain relief in response to at least 4 weeks of physical therapy. * Failure to ach…
Interventions
- DeviceDeep Brain Stimulation of the Subgenus Cingulate Cortex
The Abbott Infinity DBS device will be surgically implanted in the bilateral subgenual cingulate cortex to provide electrical stimulation to this region.
