What to Expect From The Epidural Steroid Injection Process
Epidural steroid injections are a quick and minimally invasive treatment. The procedure involves cleaning and numbing the injection site before administering the injection. While most patients do not require anesthesia, sedation is available if needed. It is advised to arrange for someone to drive you home from your Kyle pain center after the procedure, as driving or engaging in rigorous activities is not recommended for 24 hours post-treatment.
Types of Epidural Steroid Injections
Epidural steroid injections can be tailored to target specific areas of the spine, depending on the location and nature of the pain.
Interlaminar Injection
An interlaminar injection is one of the most commonly used techniques for administering epidural steroids. This type of injection is designed to target a broader area of pain, rather than focusing on a single nerve root. The procedure involves inserting a needle into the central space between the laminae of the vertebrae, typically in the lumbar or cervical region of the spine. The corticosteroid is then delivered into the epidural space, where it can spread over a wide area to reduce inflammation and pain. This approach is particularly beneficial for patients who have generalized spinal pain or multiple areas of discomfort, as it provides broad relief across the affected region.
Caudal Injection
A caudal injection is a specialized technique where the steroid is delivered through the sacral hiatus, a small bony opening near the tailbone. This injection targets the lower back and sacral region, specifically the bottom of the epidural space. Caudal injections are often used for conditions like sciatica, lumbar radiculopathy, or pain stemming from the lower lumbar and sacral nerve roots. The lower entry point allows the medication to flow upward into the epidural space, making it an effective option for treating pain that radiates into the legs or originates from the lower spine. This type of injection is particularly useful for patients with lower back pain that hasn’t responded well to other treatments.
Transforaminal Injection (Nerve Block)
A transforaminal injection, also known as a selective nerve root block, is a more targeted approach that focuses on treating pain associated with a specific nerve root. During this procedure, the needle is inserted near the foramen, which is the small opening where the nerve root exits the spine. By placing the needle in close proximity to the irritated nerve, the corticosteroid can be delivered directly to the source of pain, reducing inflammation and providing precise relief. Transforaminal injections are particularly effective for conditions like herniated discs, spinal stenosis, and radiculopathy, where nerve compression leads to pain radiating along a specific nerve pathway, such as down the arm or leg. This targeted approach allows for a concentrated delivery of the steroid, which can result in more significant pain relief for the affected nerve.
