Spinal Cord Stimulation Versus Instrumentation for FBSS

Not Applicable

Recruiting

• Conditions: SCS; Failed Back Surgery Syndrome; Neuromodulation; Low Back Pain; Spinal Cord Stimulation; Spinal Fusion

• Registration Number: NCT05466110
• Lead Sponsor: University Hospital Augsburg

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.

Primary Outcome Measures

Name	Time	Method
Oswestry disability index / ODI	12 months after intervention	A patient reported outcome measure to rate pain and disability

Secondary Outcome Measures

Name	Time	Method
Pain medication	12 months after intervention	Amount of analgesics taken (drug, dose, mode of application)
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.
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
Crossover rates	12 months after intervention	Rates of crossover to another therapy arm
