What is Failed Back Syndrome?
Failed back syndrome (FBS) or post-laminectomy syndrome( PLS), refers to chronic back and/or leg pain that is experienced after spine surgery. FBS is, therefore, not so much a specific diagnosis as it is a description. .The pain may occur immediately after the surgery and never subside, or it may come up gradually.
The term implies that the patient still has significant pain despite having surgery. Common symptoms associated with FBS include dull, persistent and aching pain in the back, often at the incision site, and/or legs; sharp, pricking, and stabbing pain in the extremities may also be experienced, especially with movement.
