This two-part video demonstrates how to use ultrasound to guide viscosupplementation or steroid injection of the arthritic knee, interspersed with the corresponding ultrasound images.

Positioning of the probe is "three-quarters of the battle" in diagnosing synovitis of the wrist or hand, says Dr. DeMarco in this video. But gel technique and pressure are crucial to gaining accurate clinical information from ultrasound imaging of this condition.

(ACR2014) Our rheumatologist correspondent found three issues of particular interest: a biomarker test that has gone quickly to market, new diagnostic criteria for gout, and the potential of ultrasound for Sjögren syndrome.

(ACR2014) To this rheumatologist in attendance, the early announcement of changes to rheumatoid arthritis guidelines -- and some of the changes themselves -- were the big surprise of the American College of Rheumatology annual meeting.

(ACR2014) What looks good at the forthcoming annual meeting of the ACR? One rheumatologist offers his expectations for useful revelations, if not clinical revolutions, in the coming week.

Here Dr. DeMarco shows how to guide an injection of the hip using ultrasound. The trick is training yourself to identify the femoral neck and head and the trochanter, and then rotating the sensor to reveal the orientation of that particular joint, beneath all that tissue.

(VIDEO) The fourth "Sounding Out Arthritis" video demonstrates how to use ultrasound to distinguish gout from pseudogout, with a demonstration of probe placement and narrated ultrasound images and videos.

(VIDEO) First, a live demonstration of ultrasound probe placement to examine the Achilles tendon for enthesitis. Then, a narrated series of still slides and films showing normal and abnormal views from the ultrasound monitor.

(VIDEO) A demonstration of injection technique, followed by narrated ultrasound images from an actual procedure, show how to use ultrasound to guide aspiration and injection of the tibiotalar joint.

(VIDEO) In this brief demonstration and slide show, rheumatologist Paul DeMarco MD shows how to use ultrasound to guide a glenohumeral joint injection.
