PROMISE: Spinal Cord Stimulation Versus Instrumentation for FBSS
Study Details
Study Description
Brief Summary
Low back pain affects people of all ages and has become the leading cause of living with disability worldwide. Patients, suffering from persistent pain after spinal surgery in the absence of any clear spinal pathology are defined of having a "failed back surgery syndrome (FBSS)" and treatment of FBSS remains a great controversy in the spinal community. Apart from conservative treatment, spinal fusion remains as therapeutic option. Furthermore, minimal invasive Neuromodulation techniques might be a promising alternative. Aim of this randomized interventional multi center study is to compare treatment success in FBSS patients with either spinal cord stimulation (SCS) or fusion surgery, 12 months after intervention according to the Oswestry Disability Index (ODI) and other scales and scores. Radiological and health economic outcome also will be analysed for thorough comparison of techniques. Additionally, the safety of the interventions needs to be compared.

| Experimental: Spinal Cord Stimulation Device The spinal cord stimulators WaveWriter AlphaTM (Boston Scientific) are designed to treat chronic back or leg pain by electrically stimulating the spinal cord. It is a well established worldwide licensed device. Percutaneous lead(-s) are implanted in the epidural space of the thoracic spine during the initial procedure. After discharge a trial phase is initiated and performed according to local preferences and standard of operations (SOPs). Patients are monitored for any complications and pain reduction. If a significant pain reduction (>50 % on the NRS scale for back pain) is achieved, the permanent implantable pulse generator (IPG) is implanted. Otherwise if the therapy remains non-beneficial throughout the trial phase, the leads will be explanted. Patients are allowed to crossover in the fusion group at any point of time. |
Device: Spinal Cord Stimulation
Epidural application of electrical current to the spinal cord

| Active Comparator: Control - Lumbar Fusion surgery The control group needs to represent the standard of care of current practice. Gold standard is lumbar fusion surgery [Resnik 2005]. Surgical instrumentation will be performed according to local preferences and SOPs. Safety and efficacy of these fusion techniques have been repeatedly proven |
Procedure: Spinal Fusion Surgery
screw-rod system based spinal instrumentation

Outcome Measures
Primary Outcome Measures
- Oswestry disability index / ODI [12 months after intervention]
A patient reported outcome measure to rate pain and disability
Secondary Outcome Measures
- Adverse events [12 months after intervention]
Comparison of complication rates
- SF36 [12 months after intervention]
Score to assess quality of life
- EuroQOL 5D [12 months after intervention]
Score to assess quality of life
- hospital length of stay [through study completion, an average of 2 years]
Time measured in days, counting from the first day of hospitalization until the day of discharge of the hospitalization the surgical intervention was performed. If surgery is performed as staged procedure in two separate hospitalizations (SCS) both hospitalizations are counted as described above and days are summed up.
- Crossover rates [12 months after intervention]
Rates of crossover to another therapy arm
- Pain medication [12 months after intervention]
Amount of analgesics taken (drug, dose, mode of application)
