Therapeutic Arthrography

Articular Infiltrations
This is a technique in which the radiologist first injects an anti-inflammatory product, such as cortisone, into the joint, and then proceeds to position the needle. When the needle is in the right place, the medication is injected.

Indications: these techniques are designed to relieve articular (joint) or periarticular pain due to arthritis or inflammation.

It is important to provide before your examination, the images and reports of relevant previous examinations done elsewhere (X-Rays, MRI, CT-SCAN, Ultrasound). This is necessary for purposes of comparison.

After the infiltration or arthrography:
In the hours following the examination, discomfort may be felt at the site of injection.

Some people may feel pain (relieved by Tylenol or Advil, as well as compresses) for a day or two.

Distensive arthrography of the shoulder
A product visible to X-rays (iodine) is first injected into the shoulder joint. Imaging is then used to inject medication (cortisone) and a local analgesic, in order to distend the joint capsule of the shoulder and allow you to resume regular movements.

Unless otherwise directed by your referring physician, it is recommended that you consult a physiotherapist in order to learn the exercises to perform after your examination.

Knee – Synvisc injection
A healthy joint is comprised of cartilage and synovial fluid, which protect the bone against shock and friction. In an arthritic joint, the cartilage crumbles and the synovial fluid cannot play a protective role. This results in friction between the bones that causes pain, joint stiffness and swelling.

An injection of Synvisc helps protect the knee joint by forming a pad that protects and lubricates the joint optimally. The injected product thus has the ability to reduce the pain of arthritis in a prolonged and significant manner.

The benefits of Synvisc:
  • Lubrifies and protects the joint
  • Reduces the pain and discomfort of arthritis
  • Helps protect against cartilage damage
  • May delay the need for a complete knee replacement
  • May help to resume normal activities
