As part of a complete joint & muscle exam joint auscultation is necessary. We need to be able to answer the question “Where is the disc relative to the head of the condyle in rotation and translation?”. The answer to this question identifies disc position on both the medial pole and the lateral pole and helps us begin to assess the risks. Ultimately the definitive answer to this question requires an MRI, but auscultation is one early way to get an idea. The following video discusses doppler auscultation as well as demonstrating the technique and creating an opportunity to listen to an observe the sounds.
