Arachnoiditis definition
Arachnoiditis is an inflammaiton condition of the arachnoid membranes or 'arachnoid', one of the membranes known as meninges that surround and protect the nerves of the central nervous system, including the human brain and spinal cord in the back .
The arachnoid can become infected as adverse reactions to chemicals, infection from bacteria or viruses , as the result of direct injury to the spine, chronic compression of spinal nerves, complications from spinal surgery or other invasive spinal procedures, or the accidental intrathecal injection of steroids intended for the epidural space.
Inflammation can sometimes lead to the formation of scar tissue and adhesion that can make the spinal nerves "stick" together or a condition where such tissue develops in and between the leptomeninges.
The condition is extremely painful, especially when progressing to adhesive arachnoiditis . Another form of the condition is arachnoiditis ossificans , in which the arachnoid becomes ossified , or turns to bone, and is thought to be a late-stage complication of the adhesive form of arachnoiditis.
What is Arachnoiditis?
Arachnoiditis is named after the arachnoid membrane, which is one of the three meninges that protect the brain and spinal cord. This membrane can become inflamed due to various factors, leading to scarring and adhesion of nerve roots. Over time, these adhesions can disrupt nerve function, causing severe pain and other symptoms.
Symptoms of Arachnoiditis
The symptoms of arachnoiditis can vary depending on the severity of the condition and the nerves affected. Common symptoms include:
Chronic Pain: Often described as burning, stinging, or aching pain, primarily in the lower back, legs, or buttocks.
Neurological Issues: Numbness, tingling, or a "pins-and-needles" sensation in the extremities.
Motor Deficits: Weakness or spasms in the legs, leading to difficulty walking.
Bowel and Bladder Dysfunction: In some cases, nerve damage can result in incontinence or urinary retention.
Electric Shock Sensations: Shooting pain that radiates through the legs, often triggered by movement.
Reduced Quality of Life: The chronic and progressive nature of the disease can lead to emotional distress, depression, and anxiety.
Causes of Arachnoiditis
Arachnoiditis has multiple causes, many of which are linked to spinal injuries or interventions. These include:
Spinal Surgery: Procedures involving the spine can sometimes damage the arachnoid membrane.
Epidural Injections: Injections for anesthesia or pain relief may introduce chemicals or cause irritation.
Infections: Viral or bacterial infections, such as meningitis, can lead to arachnoiditis.
Spinal Trauma: Accidents or injuries that damage the spinal cord or surrounding structures.
Chemical Exposure: The use of certain radiographic contrast agents in diagnostic procedures, though less common today.
Diagnosis
Diagnosing arachnoiditis can be challenging, as its symptoms often overlap with other spinal conditions. Common diagnostic tools include:
MRI Scans: These are the most effective imaging tools for identifying inflammation, scarring, or adhesions in the arachnoid membrane.
Electromyography (EMG): Used to assess the electrical activity of muscles and detect nerve damage.
Patient History: A detailed account of past medical procedures or injuries can help pinpoint potential causes.
Treatment and Management
There is currently no cure for arachnoiditis, so treatment focuses on managing symptoms and improving quality of life. The main strategies include:
1. Pain Management
- Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs), anticonvulsants, or antidepressants may be prescribed to manage chronic pain.
- Opioids: In severe cases, opioids might be used, though long-term use carries risks of dependence.
- Nerve Blocks: Injections to block pain signals may provide temporary relief.
2. Physical Therapy
- Gentle exercises and stretching can help maintain mobility and reduce stiffness.
- Hydrotherapy is particularly beneficial for relieving stress on the spine.

3. Lifestyle Modifications
- Patients are often advised to avoid activities that exacerbate symptoms, such as heavy lifting or repetitive spinal strain.
- Stress management techniques, including mindfulness or yoga, can help with coping.
4. Psychological Support
- Living with chronic pain can take a significant toll on mental health. Support groups, counseling, and therapy can help patients and their families navigate these challenges.
Advances in Research
Although arachnoiditis is considered a rare condition, ongoing research is shedding light on its causes and potential treatments. Some areas of exploration include:
Stem Cell Therapy: Early studies suggest that stem cell injections may have regenerative effects on damaged spinal tissues.
Neuromodulation Devices: Spinal cord stimulators and other devices can help block pain signals.
Non-invasive Therapies: Innovations in pain management, such as virtual reality for distraction therapy, are being explored.
