Ankylosing spondylitis (AS) is a chronic, inflammatory condition that can primarily affect the spine and sacroiliac joints, leading to pain and stiffness. In our pain management practice, we often encounter patients seeking solutions to the debilitating symptoms of AS. This blog explores the condition, its progression, and the role of interventional pain management in providing relief.
What is Ankylosing Spondylitis?
Ankylosing spondylitis is a type of spondyloarthritis or spondyloarthropathy (SpA), inflammatory conditions involving the spine and pelvis. AS is unique in its tendency to cause inflammation in the sacroiliac joints at the base of the spine, which in severe cases leads to the fusion of adjacent vertebrae.
This progressive fusion can result in a condition known as "bamboo spine," where the spine becomes rigid and inflexible. While AS primarily targets the spine, it can also affect other joints and organs, such as the hips, shoulders, eyes, and even the cardiovascular system.
Who is at Risk for Ankylosing Spondylitis?
AS typically begins in early adulthood, with symptoms commonly appearing between the ages of 15 and 35. While it is more prevalent in men, women can also develop AS, although their symptoms may present differently or be less pronounced.
Risk factors for AS include:
Genetics: A strong familial link exists, especially in individuals carrying the HLA-B27 gene. However, not all HLA-B27 carriers will develop AS.
Ethnicity: AS is more common in certain populations, including those of European descent.
Gender: Males are more likely to experience the classic spinal symptoms of AS.
Recognizing the Symptoms of Ankylosing Spondylitis
Symptoms of AS often begin subtly and can be mistaken for other conditions. Understanding these symptoms is essential for early diagnosis and management.
Common symptoms include:
Lower back pain and stiffness: Often worse in the morning or after periods of inactivity, this hallmark symptom tends to improve with exercise.
Pain in the sacroiliac joints: Located where the spine meets the pelvis, inflammation in these joints can cause significant discomfort.
Reduced spinal mobility: Over time, the spine may lose flexibility, making bending and twisting difficult.
Pain in other joints: Hips, shoulders, and even small joints can be affected.
Enthesitis: Inflammation at the sites where tendons and ligaments attach to bones, commonly affecting the hips or ribs.
Fatigue: Chronic inflammation can lead to systemic fatigue.
Extra-articular symptoms: These may include uveitis (eye inflammation), psoriasis, or inflammatory bowel disease.
How is Ankylosing Spondylitis Diagnosed?
Diagnosing AS can be challenging due to the overlap of symptoms with other conditions like mechanical back pain or other types of arthritis. A thorough evaluation is crucial.
Medical history and physical exam: Your doctor will assess your symptoms, family history, and perform tests to evaluate joint mobility and tenderness.
Imaging studies:
X-rays: Can reveal early signs of sacroiliitis or later-stage vertebral fusion.
MRI: Particularly useful for detecting early inflammation in the sacroiliac joints.
Blood tests: While no specific test confirms AS, markers of inflammation (like CRP or ESR) and HLA-B27 testing can provide supporting evidence.
Potential Complications Caused by Ankylosing Spondylitis
Fusing – With severe cases of ankylosing spondylitis, new bones can form by accident, due to the body trying to heal itself, causing vertebrae to be fused together. This fusion can stiffen your rib cage can make breathing harder than normal.
Eye inflammation (uveitis) – Rapid eye pain, light sensitivity, and blurred vision.
Compression Fractures – Bones can thin and weakened vertebrae can crumble which will cause people to bend forward. Fractures in the vertebrae can put pressure on and possibly injure the spinal cord and the nerves that pass through the spine.
Heart Problems – Ankylosing spondylitis can cause problems with your aorta, the largest artery in your body. The inflamed aorta can enlarge to the point that it distorts the shape of the aortic valve in the heart, which impairs its function.
Treatment for Ankylosing Spondylitis
While there is no cure for AS, a combination of treatments can help manage symptoms, prevent complications, and improve quality of life. Interventional pain management plays a critical role in this multidisciplinary approach, complementing pharmacological and physical therapy strategies.
Lifestyle and Complementary Therapies for Ankylosing Spondylitis
In addition to interventional procedures, patients with AS often benefit from lifestyle adjustments and complementary therapies:
Physical Therapy:A tailored exercise program focusing on stretching, strengthening, and improving posture is essential for maintaining spinal mobility.
Anti-inflammatory Diet:Foods rich in omega-3 fatty acids, antioxidants, and whole grains may help reduce systemic inflammation.
Stress Management:Stress can exacerbate inflammation, so practices like yoga, meditation, or deep breathing exercises can be beneficial.
Assistive Devices:For those with significant spinal changes or mobility challenges, braces or ergonomic tools can improve comfort and functionality.
Medication Treatments for AS
Medications often form the foundation of AS management, aiming to control inflammation and prevent structural damage.
Nonsteroidal Anti-inflammatory Drugs (NSAIDs):NSAIDs, such as ibuprofen or naproxen, are often the first line of treatment for pain and stiffness.
Biologic Medications:Tumor necrosis factor (TNF) inhibitors and interleukin-17 (IL-17) inhibitors are advanced treatments that target specific inflammatory pathways, providing significant relief for many patients.
Disease-modifying Anti-rheumatic Drugs (DMARDs):Traditional DMARDs like methotrexate may be used in cases where peripheral joints are involved.
Non-Surgical Interventional Techniques to Treat Ankylosing Spondylitis
Epidural Steroid Injections (ESI):ESIs deliver corticosteroids directly into the epidural space around the spinal nerves, reducing inflammation and alleviating pain. This option is especially useful for patients experiencing radicular pain or nerve irritation.
Sacroiliac Joint Injections:These targeted injections deliver medication directly into the sacroiliac joint, reducing inflammation and providing significant pain relief for one of the most affected areas in AS.
Nerve Blocks: Temporarily block pain by targeting the nerves that innervate areas or arthritis
Radiofrequency Ablation (RFA):RFA uses heat to disable nerve pathways transmitting pain signals from the affected joints or vertebrae. This minimally invasive procedure offers longer-term relief for patients unresponsive to other treatments.
Trigger Point Injections:Muscle tension and spasms often accompany chronic pain in AS. Trigger point injections can relieve these localized areas of muscle tightness.
Spinal Cord Stimulation (SCS):For severe, refractory pain, spinal cord stimulation may be considered. This technique involves implanting a small device that sends electrical signals to interrupt pain transmission to the brain.
Surgical Options: When Is It Necessary?
Surgery is generally reserved for severe cases of AS where joint damage is extensive or spinal deformity is causing significant disability. Common surgical interventions include:
Joint replacement surgery:For severely damaged hips or knees.
Spinal surgery:To correct deformities or relieve pressure on spinal nerves.
The Importance of a Multidisciplinary Approach in Ankylosing Spondylitis
Effective management of ankylosing spondylitis often requires collaboration among specialists, including rheumatologists, physical therapists, and interventional pain management experts. This team-based approach ensures that each aspect of the condition is addressed, from inflammation control to maintaining mobility and managing pain.
Living Well with Ankylosing Spondylitis
While AS is a chronic condition, many patients lead fulfilling lives with the right combination of treatments and support. Key strategies for thriving with AS include:
Staying active: Regular, low-impact exercise can reduce stiffness and improve overall function.
Adhering to treatment plans: Following medical advice and attending regular appointments can help keep the condition under control.
Seeking support: Connecting with others who have AS through support groups or online communities can provide valuable insights and encouragement.
Final Thoughts
Ankylosing spondylitis can be a challenging condition, but with early diagnosis and a proactive treatment approach, the symptoms can be effectively managed. Interventional pain management offers numerous tools to help patients find relief, even in advanced stages of the disease.
