What is
Lumbar/Thoracic Transforaminal Epidural Steroid Injection?
A transforaminal epidural steroid injection is the injection of local anesthetic with a small amount of steroid. This medication bathes the nerve root. The nerve roots are located in the epidural space outside of the spinal cord area.
Why is a Transforaminal Epidural Steroid Injection performed?
A transforaminal epidural steroid injection is performed to help your physician diagnose the cause of your pain.
What happens during the procedure?
You will be placed in the prone position (face down) on the table. Your back will be cleansed with an antiseptic solution and your skin will be numbed with a local anesthetic. The physician will use fluoroscopy (x-ray) to guide the placement of the needle into the area of the involved nerve root. You may experience a small “shock-like” sensation. A small amount of contrast dye will be injected to identify the exact nerve root. Once the correct placement is confirmed, the doctor will inject the local anesthetic. The placement of this medication on the nerve root may cause numbness to the affected limb.
You should arrange to have someone available to assist you with standing and walking at home after the procedure.
How long does the procedure take?
Approximately 20 minutes.
Contraindications for procedure
Bleeding problems, infection, or pregnancy.
