Lomboradiculalgies persistantes ou récidivantes après traitement chirurgical

Decompressive spinal surgery fails in 10 to 30 % of cases. All clinical data and imaging studies collected since the onset of low back pain should be reviewed to determine the cause of failure. The most common cause is inappropriate use of decompressive surgery secondary to an error in interpreting the clinical and imaging data. A repeat decompressive procedure is indicated only when nerve root compression due to recurrent disc herniation or a bony outgrowth is detected. Other causes of pain, most notably nerve root scarring and arachnoiditis, should be treated conservatively (analgesics, epidural injections, and rehabilitation therapy).
