(Steroid Joint Injection; Cortisone Joint Injection; Corticosteroid Joint Injection; Cortisone Shot)
by Sarah J. Kerr, BA
Joint injections are medicines injected into a joint. They are given to reduce pain and swelling in a joint. The medicine is often a combination of corticosteroids and local anesthetic (numbing medicine). Injections may relieve pain for several weeks or months.
This treatment is most often used in joints like the hips, knees, and shoulders.
Reasons for Procedure TOP
Your doctor may recommend a joint injection if you have pain and/or swelling from:
Possible Complications TOP
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
Another possible complication is steroid flare. This is an increase in swelling of the joint. It may be caused by preservatives in the medicine mix. The flare can develop within a few hours of the injection. It may last up to three days. This swelling will go away on its own. Applying ice to the area will help.
Sometimes, you may have a reaction to the local anesthetic used. Reaction can occur up to 30 minutes after the injection and may include:
Your doctor may limit the number of injections per year (eg, no more than four injections per year). Repeated use of injections may quicken normal age-related changes in the joint. This can cause problems with cartilage, ligaments, and tendons.
Talk to your doctor about these risks before the procedure.
What to Expect TOP
Prior to Procedure
Before the procedure, your doctor will do a physical exam. Your doctor will also discuss risks associated with joint injections. Joint injections may not be a good choice if you:
Your doctor may use a local anesthetic on your skin before giving the injection. This will make the area numb for a short time. Your doctor may also use a cold treatment to numb the skin.
Description of the Procedure TOP
This procedure can usually be done in your doctor's office.
Your doctor will locate the site where the injection will be placed. The area may be marked with a pen or marker. The injection area will be wiped with an alcohol pad.
Your doctor may flex the joint being injected. The doctor will then inject the joint in the area where it is most swollen and tender. The needle will be inserted to the bone. It is then pulled back slightly before the injection is given.
The local anesthetic may provide immediate relief. It will also help your doctor confirm the diagnosis. The steroid may provide relief from pain, swelling, and inflammation for a longer period of time.
