What is Hydrodilatation?
Hydrodilatation or hydraulic arthrographic capsular distension or distension arthrography is a medical treatment for adhesive capsulitis of shoulder. The treatment is applied by a radiologist assisted by a radiographer. Contrast medium, a local anaesthetic and cortisone are injected into the joint. Then up to 40ml of sterile saline solution are injected, using X-ray as guidance, to stretch the joint capsule. Risk of complications is low. Whether the treatment is successful is known after a couple of weeks.
