title: The failed back syndrome: personal opinions and experiences.
abstract: The author presents his personal opinion on failed back syndrome. The most frequent causes were a not indicated or contraindicated operation; a wrong site of surgery; an incomplete decompression; an omitted fusion; a pseudoarthrosis of a fusion; a recurrent disc herniation. Epidural scar is considered an enhancing factor for symptoms. Psychosocial factors are very important prognostic elements.
