About Spinal Injections
Spinal injections are performed either to confirm a suspected diagnosis or to reduce pain and inflammation resulting from spinal problems. These injections are performed under fluoroscopy by an neuro interventional radiologist.
Several types of spinal injections are performed, including epidural steroid injections and facet-sacroiliac joint injections.
Patient Information for Spinal Injections FAQ
An epidural steroid injection is done to relieve pain caused by spinal degeneration, spinal stenosis (narrowing that exerts pressure on nerves), or disc herniation or protrusion. The steroid helps to relieve pain by reducing the inflammation. While some patients attain pain relief with a single injection, others may require multiple injections over a period of time.
Facet-sacroiliac joint injections also are prescribed to alleviate pain. The facet joints connect and stabilize the vertebrae, guiding and restricting movement of the spine. The sacroiliac joint, also known as the SI joint, connects the sacrum (the triangular bone at the bottom of the spine) to the pelvis. The steroid relieves pain by reducing the inflammation.
What to expect
You will lie on your stomach on a X-ray table. First, the region of your back requiring injection will be cleaned and prepped. The radiologist will then insert a small needle in the area and, guided by X-ray imaging, will inject a small amount of contrast material to confirm proper needle placement. Once confirmation is made, the radiologist will inject the medicine and remove the needle.
Patient preparation
You should not eat solid foods during the four hour period before the procedure.
Side effects and complications
Possible complications include a small chance of infection or bleeding.
If the fluid space around the nerve in the spine is inadvertently entered during an epidural steroid injection, you may have a small chance of a post-procedure headache. Occasionally, patients may describe pain in the area where the needle was placed, transient headaches or leg weakness. Any of those symptoms should disappear within a few hours. If symptoms persist, please contact our office for further assistance.
Follow-up care
You will be advised to avoid strenuous activities for a certain time following the procedure. Do not drive until at least the next day.
