An arthrogram is a procedure in which contrast material is injected into a joint. The contrast injection is performed with help of fluoroscopy guidance (live pictures).

After the injection, pictures are taken with CT or MRI to view muscles, tendons and ligaments of the affective joint.

Do not take any blood thinners or anti-inflammatories for 3 days prior to the procedure.

You will lay on a table with your affected joint under the fluoroscope. The area is cleaned with an antiseptic soap and draped with a sterile towel. You are given an injection to numb the area of interest. A needle is then inserted into the affected joint, contrast is injected and the needle is removed. Pictures are taken with the fluoroscope and you may either have a CT or MRI after the arthrogram.

Rest the joint for about 12 hours and minimize strenuous activity for 1 to 2 days.
