All Joint and Bursa Injections
Joint injections usually are performed after administering local anesthesia. The joint is entered with a needle attached to a syringe. At this point, either joint fluid can be obtained and used for laboratory testing or medications can be injected into the joint. This technique also applies to injections into a bursa or tendon sheath to treat bursitis and tendonitis. Discussing the benefits and risks with your doctor is strongly encouraged; results vary on a case-to-case basis.
