Interventional pain management procedures are minimally invasive treatments performed by pain specialists to provide relief for patients suffering from chronic pain conditions. Common procedures include steroid injections, nerve blocks, radiofrequency ablation, and other techniques. Steroid injections and nerve blocks involve injecting medications near damaged or irritated nerves to reduce inflammation and pain signals. Radiofrequency ablation uses heat generated from radio waves to destroy targeted nerves and disrupt pain signals sent to the brain. These procedures are aimed at managing pain without the need for oral pain medications or surgery when conservative treatments have not provided adequate relief.
Steroid Injections for Arthritis and Musculoskeletal Pain
Steroid injections are one of the most widely used interventional pain management techniques. Corticosteroids are powerful Interventional Pain Management that can help reduce swelling and irritation around joints, tendons, or other structures affected by conditions like osteoarthritis, bursitis, or tendinitis. During an injection, a thin needle is used to precisely deliver very small doses of steroid medication to the area causing pain. For joint problems like knee or hip arthritis, injections are commonly used along with physical therapy and exercise to improve mobility and function while cutting down on inflammation and pain. Steroid injections may need to be repeated every 3-6 months as their effects are usually temporary. However, they provide valuable short-term relief for many patients.
Epidural Injections for Back and Leg Pain
One of the most common uses of interventional techniques is epidural steroid injections for managing low back pain and sciatica. Epidural injections involve inserting a needle into the epidural space of the spine, located just outside the dural sac containing the spinal cord. Once in the epidural space, medications like corticosteroids can be administered to reduce inflammation, swelling, and pressure on spinal nerves. For patients with radicular leg pain caused by a herniated disc or spinal stenosis, epidural injections paired with physical therapy are often the first-line treatment tried before considering back surgery. Multiple injections may be needed over months for best results with chronic lumbar radiculopathy.
Facet Joint Injections and Radiofrequency Ablation
The small facet joints located along the sides and back of the spine can become arthritic or damaged, leading to neck or back pain. During diagnostic facet joint injections, an anesthetic medicine is used determine if the facet joints are a primary contributor to a patient's pain. If pain is reduced during diagnostic injections, therapeutic injections with corticosteroids may help control long-term facet joint pain. For some patients, radiofrequency ablation of facet joint nerves can provide more sustained relief. RFA involves using small radiofrequency probes to heat and destroy targeted nerves serving the painful facet joints, interrupting pain signals for 6 months or longer in many cases.
Trigger Point Injections for Myofascial Pain
Tight, irritable muscle "knots" called trigger points can develop throughout the body in muscles like the shoulders, neck, lower back, or hips and become chronic pain generators. Using precise needle placement, interventional specialists can inject trigger points with local anesthetics or anti-inflammatory medication cocktails. This helps relax contracted muscles and provide relief from referred pain caused by muscle knots. Trigger point injections may be curative if given early in myofascial pain development but often require repetition to sustain benefits with chronic myofascial pain syndromes. Pairing injections with dry needling and physical therapy maximizes outcome.
Managing Pain Through Comprehensive Treatment
While interventional techniques can greatly improve quality of life for chronic pain sufferers when used properly, they are considered only one aspect of a complete pain management plan. The goal of interventional specialists is not just short-term pain relief but sustainable solutions through multimodal care including medications, physical/occupational therapy, medical devices, counseling, or surgery if needed.
By targeting specific anatomical or neurological drivers of persistent pain, minimally invasive treatments augment conservative approaches holistically addressing the biopsychosocial factors influencing a patient's experience of chronic pain. With a comprehensive treatment model centered on functional restoration and pain self-management, interventional pain procedures optimize outcomes for better long-term management of many pain conditions.
