What is a Targeted Epidural Injection (Nerve Root Block)?
A targeted epidural injection is an injection of local anesthetic and steroid injected into the area where the nerve exits the spinal column. A nerve root block is usually ordered to treat pain in the arm or leg that follows the path of a single nerve.
How Are Targeted Epidural Injections performed?
In a selective nerve root block, a small needle is placed in the foramen alongside the nerve root and the medication is injected.
Why are Targeted Epidural Injections performed?
When the nerves in the foramina are irritated or pinched by a bulging disk, narrowed “nerve canal” or bone spur, the resulting inflammation can cause pain, numbness, or tingling. The local anesthetic can reduce reduce the pain and other symptoms which may provide diagnostic information to your doctor.
How long does the procedure take?
The injection takes just a few minutes and is done on an outpatient basis.
