Facet Joint Injections
Eligibility for Facet Joint Injections
Individuals with back pain or pain believed to emanate from the back are suitable candidates for facet-joint injections. Such pain can arise from causes like injury, spinal stenosis, sciatica, or osteoarthritis. While the pain typically manifests in the lumbar region, it can occur anywhere along the spine. Inflamed facet joints can result in pain experienced in various regions, including the groin, buttocks, hips, shoulders, neck, legs, or arms.
Facet joint injections are often recommended when conservative measures such as anti-inflammatory medications and physical therapy have failed.
The Facet Joint Injection Procedure
During the procedure, the injection site is numbed with an anesthetic. A needle is then carefully inserted into the facet joint through the back, guided by fluoroscopy for precise placement. Once the needle is accurately positioned, a blend of anesthetic and cortisone is injected into the targeted joint. The procedure takes less than 30 minutes.
Immediate pain relief is achieved through the injected anesthetic, while it takes several days to evaluate the effects of the cortisone. Mild discomfort at the injection site may occur, which can be managed with Tylenol and ice application.
Recovery and Results
Patients can return home shortly after the injection(s) and resume normal activities the next day. A follow-up visit to the doctor occurs in approximately a week to assess the effectiveness of the injection in alleviating symptoms. Results of facet joint injections can vary significantly, with some experiencing long-term relief after a single injection, while others may require additional treatment within a few weeks or months.
Risks of Facet Joint Injections
Although generally safe, facet joint injections do carry some risks. In rare cases, they may lead to infection, allergic reactions, bleeding, or nerve damage.
