Arachnoiditis is a debilitating condition that affects the network of nerves along the spine, causing various complications. With approximately 25,000 cases reported each year, this neurologic pain condition can be caused by a range of factors, including complications from infections and surgeries. Although research on arachnoiditis is still ongoing, it is crucial to provide individuals with this condition the necessary information and relief for them to live a comfortable life, especially when it comes to managing spinal pain.
Understanding Arachnoiditis
Arachnoiditis is a condition characterized by painful inflammation of the arachnoid mater, a protective membrane located between the innermost layer, known as the pia mater, and the outermost layer, the dura mater. This inflammation occurs when collagen builds up between the pia and arachnoid layers, leading to the fusion of nerve roots and disrupting blood supply, ultimately resulting in atrophy. While arachnoiditis can occur anywhere along the spine, it was previously more commonly observed in the upper spine. However, since the 1950s, medical professionals have noticed a shift, with arachnoiditis now being more prevalent in the lumbar spine.
Causes: Epidurals
Epidurals, known as LESI or lumbar epidural steroid injections, are commonly administered to individuals experiencing spinal nerve inflammation, which is often a symptom of herniated discs and other disc diseases. The procedure involves injecting the medication outside the dura mater, the protective covering of the spinal cord. However, research indicates that in certain cases, this technique can result in a condition called adhesive arachnoiditis. Medical professionals suspect that the steroid used in the injection contains a polyether compound that can spread into the arachnoid layer from the dura layer, causing the nerves to fuse together.
