disk puncture

A short scalpel cut is made in the skin. Through the skin incision the 18-gauge needle is inserted under continuous lateral fluoroscopy control parallel to the 22-gauge needle. The tip of the 18-gauge needle must reach the posterior part of the nucleus pulposus. Patient must be monitored for pain during the whole intervention and the needle has to be repositioned if radicular pain occurs. In order to confirm contained disk herniation, or if any doubt persists, a discography can be performed just before PLDD.
