<p begin="00:00:07.299" end="00:00:08.884" style="s2">- [Voiceover] A linear array transducer</p>
<p begin="00:00:08.884" end="00:00:11.445" style="s2">with a musculoskeletal exam type is used</p>
<p begin="00:00:11.445" end="00:00:15.224" style="s2">to perform and ultrasound<br />examination of the olecranon.</p>
<p begin="00:00:15.224" end="00:00:18.477" style="s2">The patient is asked to<br />flex their elbow 90 degrees</p>
<p begin="00:00:18.477" end="00:00:21.409" style="s2">with the hand placed on<br />the examination table.</p>
<p begin="00:00:21.409" end="00:00:24.451" style="s2">The transducer is placed<br />over the posterior elbow</p>
<p begin="00:00:24.451" end="00:00:27.501" style="s2">in a longitudinal fashion<br />with the orientation marker</p>
<p begin="00:00:27.501" end="00:00:30.104" style="s2">directed toward the patient's head.</p>
<p begin="00:00:30.104" end="00:00:32.221" style="s2">The distal triceps muscle appears</p>
<p begin="00:00:32.221" end="00:00:34.988" style="s2">as a hypoechoic striated structure,</p>
<p begin="00:00:34.988" end="00:00:38.403" style="s2">which transitions to the<br />fibular triceps tendon.</p>
<p begin="00:00:38.403" end="00:00:40.558" style="s2">The olecranon is seen as a bright,</p>
<p begin="00:00:40.558" end="00:00:43.159" style="s2">hyperechoic curved structure.</p>
<p begin="00:00:43.159" end="00:00:46.296" style="s2">The posterior fat pad<br />can be seen as a complex</p>
<p begin="00:00:46.296" end="00:00:51.170" style="s2">hyperechoic area overlying the<br />posterior olecranon recess.</p>
<p begin="00:00:51.170" end="00:00:54.787" style="s2">The transducer is rotated<br />90 degrees counterclockwise</p>
<p begin="00:00:54.787" end="00:00:56.538" style="s2">with the orientation marker directed</p>
<p begin="00:00:56.538" end="00:00:58.738" style="s2">toward the patient's right side.</p>
<p begin="00:00:58.738" end="00:01:02.604" style="s2">The triceps tendon appears as<br />a hyperechoic oval structure</p>
<p begin="00:01:02.604" end="00:01:06.224" style="s2">overlying the hyperechoic<br />surface of the olecranon.</p>
<p begin="00:01:06.224" end="00:01:09.558" style="s2">Gentle backward and forward<br />rocking of the patient's elbow</p>
<p begin="00:01:09.558" end="00:01:12.122" style="s2">may be helpful to shift elbow joint fluid</p>
<p begin="00:01:12.122" end="00:01:15.872" style="s2">into the olecranon<br />recess for visualization.</p>
