<p begin="00:00:07.711" end="00:00:09.526" style="s2">- [Voiceover] A<br />linear-array transducer with</p>
<p begin="00:00:09.526" end="00:00:12.155" style="s2">a musculoskeletal exam<br />type is used to perform</p>
<p begin="00:00:12.155" end="00:00:16.827" style="s2">an ultrasound examination of<br />the flexor tendon of the ankle.</p>
<p begin="00:00:16.827" end="00:00:19.167" style="s2">The patient is placed in a supine position</p>
<p begin="00:00:19.167" end="00:00:21.755" style="s2">with the foot rotated slightly laterally</p>
<p begin="00:00:21.755" end="00:00:24.852" style="s2">and a pillow under the lateral malleolus.</p>
<p begin="00:00:24.852" end="00:00:27.174" style="s2">The transducer is placed obliquely behind</p>
<p begin="00:00:27.174" end="00:00:30.348" style="s2">the medial malleolus with<br />the orientation marker</p>
<p begin="00:00:30.348" end="00:00:32.705" style="s2">directed toward the patient's right.</p>
<p begin="00:00:32.705" end="00:00:34.588" style="s2">The medial melleolus is seen as</p>
<p begin="00:00:34.588" end="00:00:37.115" style="s2">a bright, hyperechoic structure.</p>
<p begin="00:00:37.115" end="00:00:40.118" style="s2">The tibialis posterior<br />tendon can be seen as</p>
<p begin="00:00:40.118" end="00:00:43.352" style="s2">a hyperechoic, compact fibular structure</p>
<p begin="00:00:43.352" end="00:00:46.051" style="s2">posterior to the malleolus.</p>
<p begin="00:00:46.051" end="00:00:48.861" style="s2">The flexor digitorum<br />longus tendon appears as</p>
<p begin="00:00:48.861" end="00:00:52.096" style="s2">a rounded, hyperechoic<br />structure immediately lateral</p>
<p begin="00:00:52.096" end="00:00:54.308" style="s2">to the tibialis tendon.</p>
<p begin="00:00:54.308" end="00:00:57.044" style="s2">Compressible posterior<br />tibial veins can be seen</p>
<p begin="00:00:57.044" end="00:01:00.621" style="s2">as dark, round, hypoechoic areas.</p>
<p begin="00:01:00.621" end="00:01:03.238" style="s2">The posterior tibial artery can be seen</p>
<p begin="00:01:03.238" end="00:01:06.293" style="s2">as a rounded, pulsatile structure.</p>
<p begin="00:01:06.293" end="00:01:08.347" style="s2">The flexor retinaculum is seen as</p>
<p begin="00:01:08.347" end="00:01:11.449" style="s2">a linear, hyperechoic<br />band which is superficial</p>
<p begin="00:01:11.449" end="00:01:14.782" style="s2">to these structures in the medial ankle.</p>
