Home Epidural Fibrosis

Epidural Fibrosis is scarring that naturally occurs after back surgery. It is one of several possible causes of a condition known as failed back surgery syndrome (FBSS). Epidural fibrosis is perhaps the most common cause of FBSS.

Scarring is a natural response to any type of wound that disrupts a body structure, and the area around your spinal nerve root during surgery is no exception. The process is similar to what happens when you scrape a knee; in other words, the development of the epidural fibrosis is comparable to the scab that forms on your knee after the initial injury. The scab and the epidural fibrosis are natural healing processes.

Once the scars form, there’s no genuinely effective treatment. Your surgeon may want to go back in and break up the scars with an endoscope, but this actually can result in more scarring and epidural fibrosis.

Epidural scarring generally happens between six and 12 weeks after the surgery. Epidural fibrosis is similar to but different from a rare chronic pain condition called arachnoiditis that can also occur after back surgery. First, epidural fibrosis affects the outermost covering of the spinal cord (the dura mater,) whereas arachnoiditis goes a layer deeper into the arachnoid membrane. Like the dura mater above it (and the pia mater beneath) the arachnoid surrounds and protects the sensitive nerves that comprise the spinal cord.

Typically, symptoms associated with epidural fibrosis (scar tissue around the nerve root) appear at 6 to 12 weeks after back surgery.

The best way to treat epidural fibrosis is to prevent it, or at least to reduce the formation of the scar.
