It is very important that occurate diagnosis of the level and location of lumbar disc herniation is made, before surgery is carried out. Recently, the diagnosis of lumbar disc herniation has been made easier with magnetic resonance imaging.We performed a nucleotomy in 22 cases of lumbar disc herniation, which were only diagnosed by magnetic resonance imaging. All cases achieved a good results post-operatively.We concluded that we could operate upon herniated nucleus pulposus diagnosed only by MRI without myelography or CTM. But care must be taken when there is neurological disagreement, spondylosis deformens, central type herniation, old age, or cases requiring re-operation.It is more important to have static rather than dynamic information from MRI, therefore we should perform nucleotomy, rather than instrument surgery.
