Deep back pain can also be treated using a combination of anti-inflammatory and local analgesic (pain killing) substances which are injected directly into the spinal cord or the spinal canal. There are a variety of procedures to do this.
Widely used is the catheter procedure named after (Prof. Racz-Katheter). Here, a catheter is directly inserted into the lower end of the spine into the sacral region and left in there for 3 days. This biggest disadvantage of this treatment method is that there is a high risk of infection and that patients must stay in hospital.
Thus, we prefer the caudal block (caudal injection) procedure which avoids this problem.
