<p begin="00:00:07.460" end="00:00:09.135" style="s2">- [Voiceover] A linear array transducer</p>
<p begin="00:00:09.135" end="00:00:11.309" style="s2">with a musculoskeletal exam type</p>
<p begin="00:00:11.309" end="00:00:13.848" style="s2">is used to perform an<br />ultrasound examination</p>
<p begin="00:00:13.848" end="00:00:15.776" style="s2">of the medial elbow.</p>
<p begin="00:00:15.776" end="00:00:18.227" style="s2">The patient is placed in a supine position</p>
<p begin="00:00:18.227" end="00:00:19.982" style="s2">with the elbow slightly flexed,</p>
<p begin="00:00:19.982" end="00:00:22.782" style="s2">and the forearm forcefully<br />externally rotated</p>
<p begin="00:00:22.782" end="00:00:25.412" style="s2">and resting on the examination table.</p>
<p begin="00:00:25.412" end="00:00:28.394" style="s2">The transducer is placed<br />over the medial epicondyle</p>
<p begin="00:00:28.394" end="00:00:31.456" style="s2">in a longitudinal fashion,<br />with the orientation marker</p>
<p begin="00:00:31.456" end="00:00:34.130" style="s2">directed towards the patient's head.</p>
<p begin="00:00:34.130" end="00:00:35.756" style="s2">The flexor tendon can be seen</p>
<p begin="00:00:35.756" end="00:00:38.481" style="s2">as a fibrillar patterned structure.</p>
<p begin="00:00:38.481" end="00:00:40.264" style="s2">The medial epicondyle is seen as</p>
<p begin="00:00:40.264" end="00:00:42.946" style="s2">a bright, hyperechoic, curved structure</p>
<p begin="00:00:42.946" end="00:00:45.026" style="s2">lying below the tendon.</p>
<p begin="00:00:45.026" end="00:00:48.006" style="s2">The anterior bundle of the<br />medial collateral ligament</p>
<p begin="00:00:48.006" end="00:00:50.840" style="s2">can be seen as a thin, hyperechoic band</p>
<p begin="00:00:50.840" end="00:00:54.562" style="s2">that runs between the medial<br />epicondyle and the ulna.</p>
<p begin="00:00:54.562" end="00:00:56.968" style="s2">Dynamic scanning with valgus stress</p>
<p begin="00:00:56.968" end="00:00:59.964" style="s2">can be used to evaluate the<br />medial collateral ligament</p>
<p begin="00:00:59.964" end="00:01:01.881" style="s2">for laxity or injuries.</p>
