Failed back surgery syndrome is a term that is used to describe the condition resulting when a person has an unsuccessful back or spine surgery. Failed back surgery syndrome is not an official diagnosis; it is a term used in the medical field.
According to Spine-Health, back and spine surgery have a 95-percent success rate. Identifying the cause of back pain is necessary when discussing surgical options. Causes of failed back surgery syndrome might include failure of an implant, failure of a fusion, scar tissue, disc herniation and difficulties from postoperative rehabilitation. During recovery, people who undergo back or spine surgery can expect to experience leg pain, lower back pain and pain around any incisions.
