Multicolumn spinal cord stimulation for predominant back pain in failed back surgery syndrome patients: a multicenter randomized controlled trial.
Summary
The purpose of this study is to compare the effectiveness of spinal cord stimulation (SCS) using the Medtronic Specify® 5-6-5 multicolumn surgical lead plus optimal medical management (OMM) versus OMM alone in patients suffering from predominant low back pain due to failed back surgery syndrome (FBSS).

Eligibility Criteria
Inclusion Criteria
- SCS candidate with the Specify 5-6-5 surgical lead
- Has FBSS and does not require further surgery (defined as persistent or recurrent low back and leg pain of at least 6 months duration following at least one decompression and/or fusion procedure)
- Average low back pain is ≥ 5 as assessed by the baseline NPRS
- Average low back pain is greater than leg pain
- Subject has persistent moderate to severe low back and leg pain despite other treatments
Exclusion Criteria
- Treated with SCS, subcutaneous or peripheral nerve stimulation, an intrathecal drug delivery system, requires back surgery at the location related to his/her original back pain complaint or experimental therapies
- Most recent back surgery < 6 months ago
- Low back pain only (no leg pain)
- Investigator suspects substance abuse that might confound the study results
- Radiographic evidence of instability requiring fusion
- Pain relieved completely by lying down
- Life expectancy of < 24 months
- Subject is pregnant or planning to become pregnant during the course of the study
- Subject is unable to undergo study assessments or complete questionnaires independently
