Lateral Method for Nerve Root Block

Abstract

We report our experience in nerve root block using the lateral approach in 13 out of 337 cases (11 males, two females), whose average age was 65. Of the 13, ten underwent surgical therapy. The lateral approach was used because patients could not maintain prone and oblique positions. Many had lateral disc herniation. Only the walking disability score of JOABPEQ differed significantly between the lateral and prone approaches. Nerve root block with the lateral approach is useful for upper lumbar lateral disc herniation in patients who are unable to maintain prone and oblique positions due to lumbar disc disease.
