Doppler Joint Auscultation

By Lee Ann Brady on 03.05.13Category: Occlusion/TMD, Videos

Great Lakes Doppler in Place on Lateral Pole

A critical piece of joint diagnosis is being able to differentiate the sounds we hear using auscultation. Based on the way load is applied in varying positions we know that in a seated condylar position and through rotation the load is on the medial aspect of the condyle/disc assembly. During translation the load moves out to the lateral aspect. By listening to the joint during rotation, which is the first 10mm or so of opening and the condylar movement on the working side during an excursive we can get information about the disc position. Translation occurs when listening on the balancing side during an excursive or during the rest of the opening movement. Doppler is one of my favorite ways to listen to a joint as both the patient and I can hear the sounds. In this video, recorded as part of a larger segment of the doing a joint exam for HDIQ, I demonstrate using a doppler.

    Thank you for the demostration. Seems a little subjective and difficult to hear the sounds over the background noise. I saw a demo of Joint vibrational analysis, which generates a graph of the joint sounds. JVA seems more quantative,but is the science really there on JVA?

    What are the treatment options for people with medial disc displacement? Can I restore people with Pipper IVa or IVb joints?
