[Topographic forms of herniated lumbar discs. Contribution of saccoradiculographie and zonographie].
The clinical signs of herniated lumbar disc do not always allow to settle their level. Therefore authors add, to sacco-radiculography with standard plates, frontal zonographic sections. Then, they study radiographic findings and segregate some particular topographic forms of herniated discs: 1) with fragment behind verebral body, 2) with deviated root outside the disc herniation, 3) in front of the lamina and behind the root. Some of them have their own clinical signs, especially paralysed forms of L5 sciatic with abolition of achilean reflexe. Further more they propose hemilaminectomy for total removal of herniated lumbar discs with fragment behind the vertebral body. They conclude to advantage of usually making a saccoradiculography with the dimer iothalamate of methyl glucamine (Dimer X) before each operation.
