Joint injection
Joint Injection
A Joint Injection (pronounced: jɔɪnt ɪnˈdʒɛkʃən) is a medical procedure used to treat inflammatory joint conditions, such as rheumatoid arthritis, psoriatic arthritis, gout, tendinitis, bursitis and occasionally osteoarthritis.
Etymology
The term "Joint Injection" is derived from the Latin words 'iunctus', meaning 'joined', and 'injectionem', meaning 'a throwing in', referring to the method of administering the treatment.
Procedure
A joint injection typically involves injecting medications directly into the joint cavity. The most common types of medications used are corticosteroids and hyaluronic acid. Corticosteroids are powerful anti-inflammatory agents that can reduce inflammation and pain. Hyaluronic acid is a type of lubricant that can help improve joint function and reduce pain.
Risks and Complications
While joint injections are generally safe, they can occasionally cause side effects or complications. These may include infection, allergic reactions to the medication, bleeding, and damage to the joint tissue. In rare cases, a joint injection can lead to a temporary increase in pain and swelling.
