<p begin="00:00:10.011" end="00:00:12.732" style="s2">- Today we're going to<br />examine the shoulder.</p>
<p begin="00:00:12.732" end="00:00:15.420" style="s2">There are multiple protocols<br />available for the shoulder,</p>
<p begin="00:00:15.420" end="00:00:17.859" style="s2">however I've found some<br />simplified techniques</p>
<p begin="00:00:17.859" end="00:00:20.246" style="s2">and I think what's most important is</p>
<p begin="00:00:20.246" end="00:00:22.034" style="s2">to maintain a consistent protocol</p>
<p begin="00:00:22.034" end="00:00:23.825" style="s2">and repetitively go over it and over it</p>
<p begin="00:00:23.825" end="00:00:26.716" style="s2">until you're comfortable<br />with what exam works for you.</p>
<p begin="00:00:26.716" end="00:00:29.474" style="s2">In looking at the shoulder, I<br />recommend that the patient's</p>
<p begin="00:00:29.474" end="00:00:31.301" style="s2">in the seated position.</p>
<p begin="00:00:31.301" end="00:00:34.226" style="s2">I prefer to stand behind the<br />patient so that I can look</p>
<p begin="00:00:34.226" end="00:00:36.676" style="s2">at the screen, which is in front of me</p>
<p begin="00:00:36.676" end="00:00:40.572" style="s2">at approximately a 2<br />o'clock window for me so</p>
<p begin="00:00:40.572" end="00:00:42.879" style="s2">that the patient and myself<br />can both look at the screen</p>
<p begin="00:00:42.879" end="00:00:45.242" style="s2">an interact and educate the patient while</p>
<p begin="00:00:45.242" end="00:00:47.103" style="s2">I'm doing the scan.</p>
<p begin="00:00:47.103" end="00:00:48.370" style="s2">In examining the shoulder,</p>
<p begin="00:00:48.370" end="00:00:50.207" style="s2">there are some important<br />principles to follow.</p>
<p begin="00:00:50.207" end="00:00:53.130" style="s2">First of all, when holding the transducer,</p>
<p begin="00:00:53.130" end="00:00:56.656" style="s2">it's easiest to have the<br />notch of the transducer</p>
<p begin="00:00:56.656" end="00:00:59.875" style="s2">always facing upwards or<br />cephalad on the patient.</p>
<p begin="00:00:59.875" end="00:01:02.803" style="s2">That will always be your<br />lighthouse so to speak</p>
<p begin="00:01:02.803" end="00:01:05.888" style="s2">of exactly where you are, so I<br />always keep the notch upward,</p>
<p begin="00:01:05.888" end="00:01:08.234" style="s2">as well as looking at the<br />upper left hand corner</p>
<p begin="00:01:08.234" end="00:01:12.265" style="s2">of the screen to making sure<br />I know exactly where I am.</p>
<p begin="00:01:12.265" end="00:01:14.020" style="s2">I'm going to using a linear transducer</p>
<p begin="00:01:14.020" end="00:01:16.130" style="s2">and this is a high frequency probe,</p>
<p begin="00:01:16.130" end="00:01:18.232" style="s2">which allows us the optimal resolution</p>
<p begin="00:01:18.232" end="00:01:20.033" style="s2">in musculoskeletal imaging.</p>
<p begin="00:01:20.033" end="00:01:21.860" style="s2">With examination of the shoulder,</p>
<p begin="00:01:21.860" end="00:01:23.764" style="s2">I prefer the musculoskeletal setup.</p>
<p begin="00:01:23.764" end="00:01:26.767" style="s2">I press the exam button<br />and I check to make sure</p>
<p begin="00:01:26.767" end="00:01:29.740" style="s2">that I'm on the musculoskeletal<br />setting and press select.</p>
<p begin="00:01:29.740" end="00:01:33.431" style="s2">Next it's important to know<br />what depth you'd like to do</p>
<p begin="00:01:33.431" end="00:01:35.743" style="s2">for the exam and here for starters,</p>
<p begin="00:01:35.743" end="00:01:40.296" style="s2">I'm going to begin at 3.3,<br />which is noted on the screen.</p>
<p begin="00:01:40.296" end="00:01:43.922" style="s2">I can move up or down and<br />the closer to the surface</p>
<p begin="00:01:43.922" end="00:01:48.089" style="s2">of the skin, the better clarity<br />and resolution I'll have.</p>

<p begin="00:00:09.561" end="00:00:12.559" style="s2">- Next, I'm going to examine<br />the subscapularis tendon.</p>
<p begin="00:00:12.559" end="00:00:16.130" style="s2">I start with the patient<br />again with his palm up</p>
<p begin="00:00:16.130" end="00:00:19.226" style="s2">at the bicep tendon in<br />the cross-sectional view</p>
<p begin="00:00:19.226" end="00:00:22.797" style="s2">with my hand on the patient's shoulder,</p>
<p begin="00:00:22.797" end="00:00:25.299" style="s2">identify the bicep tendon.</p>
<p begin="00:00:25.299" end="00:00:27.624" style="s2">Next I'm going to have the<br />patient slowly externally</p>
<p begin="00:00:27.624" end="00:00:29.874" style="s2">rotate his arm to the side.</p>
<p begin="00:00:31.365" end="00:00:34.448" style="s2">What this does is opens up<br />the subscapularis tendon</p>
<p begin="00:00:34.448" end="00:00:36.531" style="s2">so we can clearly see it.</p>
<p begin="00:00:38.449" end="00:00:40.047" style="s2">Oftentimes, I'll have the patient resist</p>
<p begin="00:00:40.047" end="00:00:42.832" style="s2">against my hand in internal rotation</p>
<p begin="00:00:42.832" end="00:00:44.840" style="s2">to detect any pathology.</p>
<p begin="00:00:44.840" end="00:00:45.921" style="s2">Push against my hand.</p>
<p begin="00:00:45.921" end="00:00:47.616" style="s2">Good, relax.</p>
<p begin="00:00:47.616" end="00:00:48.449" style="s2">And again.</p>
<p begin="00:00:49.362" end="00:00:50.195" style="s2">Relax.</p>
