Failed Back Surgery Syndrome (FBSS)

Last updated: 11 May 2026

Failed Back Surgery Syndrome (FBSS)

Failed Back Surgery Syndrome (FBSS) sometimes referred to simply as Failed Back is a condition in which patients continue to experience back pain or radiating leg pain after spinal surgery. This may occur even after one or multiple operations, when the outcome is not as expected or when pain returns sometime after the procedure.

FBSS does not necessarily mean that the surgery itself was technically unsuccessful. Rather, it refers to the persistence or recurrence of pain that has not improved as anticipated.
Common contributing factors include:

Other underlying spinal pathology that remains unresolved
Epidural fibrosis (scar tissue around the nerves)
Malunion or abnormal bone fusion
Implant migration or instability
New problems at adjacent spinal levels (Adjacent Level Disease)
Psychological factors or central sensitization

Incidence

Research published in Pain Physician and Spine Journal indicates that:

The incidence of FBSS among postspinal surgery patients is approximately 10 - 40%.
FBSS is one of the leading causes of chronic neuropathic pain and remains a complex condition to manage.

Management of FBSS

Effective treatment of FBSS requires accurate diagnosis and a multimodal approach beyond repeat surgery.

1. Pain Intervention

Epidural Steroid Injection (ESI)
Transforaminal Epidural Injection (TESI)
Caudal Lysis of Adhesions (e.g., Racz Procedure)
Spinal Cord Stimulation (SCS)

2. Multidisciplinary Pain Program

Specialized physical therapy
Cognitive Behavioral Therapy (CBT)
Pharmacologic pain management (e.g., Gabapentin, SNRI, Tramadol)

3. Revision Surgery: Reserved for specific indications such as:

Implant failure
Pseudarthrosis
Clearly demonstrated foraminal stenosis on MRI or CT
