Arthrogram

Arthrograms can be diagnostic or therapeutic. Therapeutic arthrograms often distend the joint with cortisone and lidocaine, with a common site being the shoulder. Diagnostic arthrograms can be helpful in determining the cause of joint pain using CT scans or MRI guidance. This procedure involves injecting contrast dye into the joint to get detailed images of the affected joint’s soft tissues and surrounding structures.

Depending on the area to be injected, you will be positioned on your back or stomach on an exam table. The fluoroscopy camera (X-ray fluoroscopy) will be positioned above you. The skin around the joint to be injected will be cleansed with an antiseptic solution such as betadine.

A small needle will be placed under the skin, and numbing medicine, such as lidocaine, will be injected to numb the area. A needle will then be placed into the joint, and contrast material will be injected to confirm that the needle is in the correct location. An anesthetic will also be injected, deeper into the joint, along with saline and more contrast material, depending on the specific procedure ordered by your healthcare provider.

In most cases, a CT or MRI scan will be performed after the arthrogram to obtain more detailed images of the structure of the joint. This will take another 30-45 minutes. During the imaging, you may be asked to move the joint to get clearer images.

A summary of the procedure will be sent to your healthcare provider who will then contact you to discuss the results.

Unless directed otherwise, you may resume your normal diet and prescribed medications. To avoid any potential infection, please refrain from submerging the area in a tub or pool for 24 hours. You may shower. Rest for the remainder of the day and avoid heavy lifting and strenuous activities.

You may feel soreness at the needle insertion site for several days. You can apply ice for up to 15 minutes per hour to relieve any discomfort.

Depending on the joint to be injected, you may be asked to discontinue your blood thinner prior to the exam. This will be by the direction of your healthcare provider. Please inform us at the time of scheduling if you do indeed take a blood thinner.

If you have an active infection and are taking antibiotics, the medication course must be complete prior to the procedure. Inform us if you are or may be pregnant, or have allergies to medications or X-ray dye (contrast).

On the day of your procedure you should:

• Avoid bringing valuables or jewelry
• Wear loose, comfortable clothing
• Wear comfortable shoes
• Bring your insurance card and a valid photo ID
