Caudal Epidural

What is Caudal Epidural?

A caudal epidural injection is a procedure where a steroid medication is injected into the lower part of the epidural space in the lower back. This space surrounds the nerve roots that extend from the spinal cord. The purpose of this injection is to reduce inflammation and alleviate pain, particularly in the legs or lower back, caused by irritated or inflamed spinal nerves.

This procedure is commonly used to manage conditions such as sciatica, herniated discs, spinal stenosis, or other sources of nerve-related pain in the lumbar (lower) spine. By delivering the steroid directly into the epidural space, inflammation is reduced, which can lead to decreased pain and improved mobility for individuals suffering from these conditions. Caudal epidural injections are often part of a comprehensive treatment plan that may include physical therapy, medications, and other interventions aimed at managing chronic back pain and related symptoms.

Diseases Cured by Caudal Epidural

A caudal epidural injection is an effective treatment for various conditions causing nerve pain and inflammation. Some of the diseases and conditions that can be alleviated or managed with caudal epidural injections include:

Spinal canal stenosis: Narrowing of the spinal canal can lead to compression of nerves, resulting in pain and discomfort that may be relieved with the anti-inflammatory effects of the injection.

Failed back syndrome or post-laminectomy syndrome: This condition refers to persistent pain following back surgery, often due to scar tissue or nerve irritation, which can be targeted and reduced with caudal epidural injections.

Herniated discs: When the gel-like material within a spinal disc protrudes, it can press on nearby nerves, causing pain and inflammation that can be mitigated by the injection.

Degenerative disc disease: This condition involves the gradual deterioration of spinal discs, leading to pain and reduced mobility, which can be managed with caudal epidural injections targeting inflammation and pain relief.

Sciatica or Radiculopathy: These conditions involve irritation or compression of the sciatic nerve or other spinal nerves, resulting in radiating pain down the legs, which can be relieved with targeted injections into the epidural space to reduce inflammation and alleviate pain.

How Does It Work?

During a caudal injection procedure, you will typically lie face-down on an X-ray table, and a pillow may be placed under your abdomen for added comfort. A pain management specialist will apply a topical anesthetic (numbing medication) to your lower back, ensuring you won’t feel any discomfort during the injection process. 

Next, the specialist will use a needle to inject a dye into the epidural space. This dye helps the provider visualize the area clearly using an X-ray machine, ensuring precise placement of the medication. Once the needle is in the correct position, the provider will inject the steroid medication into the epidural space. The steroid medication works to reduce inflammation and alleviate pain by targeting the affected nerves directly, providing relief from conditions such as herniated discs, spinal stenosis, or sciatica.

Post Recovery Care

After a caudal epidural injection, patients are typically advised to follow certain post-recovery care guidelines. Firstly, it’s recommended to rest on the day following the injection, although this doesn’t necessarily mean remaining completely still once the numbness in the limbs has worn off. 

Activities such as driving, operating machinery, or consuming alcohol should be avoided for at least 24 hours after the procedure. The small dressing applied at the injection site can be removed after a few hours. It’s important to refrain from applying heat directly to the injection site for at least three days, which includes avoiding activities like using hot packs, steam rooms, or saunas. 

However, regular showering is safe. Patients should wait a full 24 hours after the injection before returning to their normal daily activities, including physical therapy or exercise, and can resume eating, drinking, and taking medications as usual. Swimming, bathing, or using hot tubs should be postponed until the day after the epidural injection.
