What Is A Lumbar Transforaminal Epidural Steroid Injection?
A lumbar transforaminal epidural steroid injection is a commonly used treatment method for radicular pain and lower back pain that is minimally invasive. Before this type of approach was established, conditions such as sciatic nerve pain or lumbar pain were usually treated with more invasive procedures such as surgery. Lumbar pain is characterized as pain that is felt in the lower back, although it may also radiate into the buttocks, thighs, and legs.
Clinical research has been repeatedly published that supports the use of epidural steroid injections for chronic pain and even intense, acute pain. The medication takes effect rapidly and pain relief usually persists for long periods of time, especially if the injection is repeated more than once. Most individuals who suffered from decreased mobility or had to miss work due to their back pain can quickly return to their normal activities after receiving steroid injections.
Clinicians and researchers have tried to elucidate the mechanism that makes epidural steroid injections so effective, but to date this information is still somewhat unclear. It has, however, been proposed that injecting an anesthetic along with anti-inflammatory steroids reduces pain that develops due to nerve damage as well as inflammation. The administration of steroids also helps restore the structure of the membranes that surround the nerves and hinder ion conduction. The restored structural integrity of the membranes along with reduced signal transmission is associated with reduced pain.
How Is A Lumbar Transforaminal Epidural Steroid Injection Performed?
Steroid injections are administered to specific regions along the spinal cord. The spinal cord is a complex structure that contains numerous nerves that extend throughout the entire body and control many processes. Cerebrospinal fluid (CSF) protects and cushions the nerves. The spinal cord is also protected by the spinal canal and is held in a stable position by a firm membrane. The area that is directly outside of this membrane, called the epidural space, is where the medication is injected. The roots of damaged nerves are the targets for steroid injections and the nerve roots are located in the epidural space.
