3.1 Epidural Steroid Injections
Epidural steroid injections are a common fluoroscopy-guided procedure to treat spinal pain and inflammation. They involve injecting a mixture of steroids and anesthetics into the epidural space surrounding the spinal cord. This method is often used to alleviate pain caused by conditions such as herniated discs, spinal stenosis, or nerve root compression. The use of fluoroscopy ensures precise needle placement, minimizing risks and improving effectiveness. These injections provide targeted relief, reducing inflammation and improving mobility for patients with chronic pain.
By delivering medication directly to the affected area, epidural injections offer a localized treatment approach, reducing systemic side effects. This procedure is particularly beneficial for patients who have not responded to conservative treatments like physical therapy or oral medications. Fluoroscopy guidance enhances accuracy, ensuring the medication reaches the intended location for optimal results.
3.2 Facet Joint Injections
Facet joint injections are fluoroscopy-guided procedures used to diagnose and treat pain originating from the facet joints, small stabilizing structures in the spine. These injections typically involve administering a combination of steroids and anesthetics into the joint or surrounding nerves to reduce inflammation and alleviate pain. Commonly used for conditions like facet syndrome or spinal pain, this method ensures precise needle placement under fluoroscopic imaging, enhancing therapeutic outcomes and minimizing complications.
The procedure is particularly effective for patients experiencing chronic back pain, as it targets the specific source of discomfort. Fluoroscopy allows real-time visualization, ensuring accurate delivery of medication directly to the affected facet joint. This targeted approach can significantly improve mobility and reduce pain in individuals with spinal disorders, making it a valuable option in pain management strategies.
3.3 Joint and Soft Tissue Injections
Fluoroscopy-guided joint and soft tissue injections are procedures used to treat pain and inflammation in joints, tendons, and ligaments. These injections often involve corticosteroids or anesthetics delivered precisely to the affected area under real-time imaging. Common applications include joint aspirations to remove fluid for diagnostic purposes and therapeutic injections to reduce inflammation in conditions like arthritis or tendinitis. Fluoroscopy ensures accurate needle placement, enhancing the effectiveness of the treatment while minimizing risks to surrounding tissues.
This technique is particularly useful for targeting deep or hard-to-reach areas, such as hip or shoulder joints, where blind injections might be less accurate. By providing clear visualization, fluoroscopy helps minimize complications and improves patient outcomes, making it a reliable choice for both diagnostic and therapeutic interventions in musculoskeletal care.
