INTERVENTIONAL TECHNIQUES

 

Transforaminal Epidural Injections

 

These are also called selective nerve root blocks or sleeve injections

 

How many types?

 

  • Cervical for neck

  • Thoracic for mid and upper back

  • Lumbar / sacral for low back

 

What is a nerve root?

 

Nerve roots exit the spinal cord and form nerves that travel into the arms or legs.  These nerves allow movement of the arms, chest wall, and legs.  These nerve roots may become inflamed and painful due to irritation, for example, from a damaged disc or a bony spur.

 

What is a transforaminal block?

 

Transforaminal or selective nerve root block provides important information to physicians, also a primary treatment in many cases.  It serves to prove which nerve is causing pain by placing temporary numbing medicine over the nerve root of concern.  If a patients usual pain improves after the injection, that nerve is most likely causing the pain.  If the pain remains unchanged, that nerve is generally not the reason a patient may be experiencing pain.

 

By confirming the exact source of pain, it provides information allowing for proper treatment, which may include additional nerve blocks and/or surgery at a specific level.

 

What happens during the procedure?

 

An IV will be started so that relaxation medication can be given.

 

The patient is placed on the x-ray table and positioned in such a way that the physician can best visualize the bony openings in the spine where the nerve roots exit the spine using x-ray guidance in the treatment room.

The skin on the spine is cleaned with alcohol.

 

Next, the physician numbs a small area of skin with numbing medicine. 

 

After the numbing medicine has been given time to be effective, the physician directs a very small needle, using x-ray guidance near the specific nerve being tested.  A small amount of contrast (dye) is injected to insure proper needle position.  Then a small mixture of numbing medicine (anesthetic) and anti-inflammatory (steroid) is injected.

 

 

 

What happens after the procedure?

 

Immediately after the procedure, the patient will move around and try to imitate something that would normally bring about their usual pain.  In the beginning of treatment phase, patient is monitored for relief and side effects.

 

The arm(s), chest wall or leg(s) may feel weak or numb for a few hours following the procedure.  This is fairly common and happens following a selective nerve root block or transforaminal epidural injection.

 

Instructions

 

The patient can eat a light meal within a few hours before the procedure.

 

If a patient is an insulin dependent diabetic, they must not change their normal eating pattern prior to the procedure.

Patients may take their routine medications. (i.e. high blood pressure and diabetic medications).

 

Post-procedure Instructions

 

You were given a number of medications during the procedure.  These sometimes include sedatives, narcotics, local anesthetics, steroids, and other medications.  Any of these drugs or procedure itself, sometimes can cause side effects, including drowsiness, temporary numbness, weakness and soreness.
