NON-OPERATIVE PROCEDURES
- Lumbar Epidural Steroid Injections
The membrane that covers the spinal cord and nerve roots in the spine is called the dura membrane. The space surrounding the dura is the epidural space. Nerves travel through the epidural space to the back and into the legs. Inflammation of these nerve roots may cause pain in these regions due to irritation from a damaged disc or from contract in some way with the bony structure of the spine.
An IV is started so that relaxation medication can be given. The patient is placed lying on their side on the x-ray table and positioned in such a way that the physician can best visualize the low back using x-ray guidance. The skin on the back is scrubbed using 2 types of sterile scrub (soap). Next, the physician numbs a small area of skin with numbing medicine. This medicine stings for several seconds. After the numbing medicine has been given time to be effective, the physician directs a small needle, using x-ray guidance into the epidural space. A small amount of contrast (dye) is injected to insure the needle is properly positioned in the epidural space. A mixture of numbing medicine (anesthetic) and anti-inflammatory (cortisone/steroid) is injected.
