MR Post-Diskectomy Imaging
The failed back surgery syndrome is a frequent condition. Burton  reported the incidence of the syndrome to be 10%–40%. This may involve disk herination (12%–16%), lateral spinal stenosis (58%), central spinal stenosis (7%–14%), arachnoiditis (6%-16%), or epidural fi-brosis (6%–8%). The crucial problem is the distinction between epidural scar and recurrent disk herniation, because only reoperation on recurrent disk herniation leads to a good surgical result.
