Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <sec id="mus24483-sec-0001" sec-type="section"> <title>Introduction</title> <p>In this anatomical study we evaluated the feasibility of ultrasound (US) guided perineural injection of the deep branch of the radial nerve (DBRN) at the arcade of Frohse as potential therapy for nerve entrapment at this site.</p> </sec> <sec id="mus24483-sec-0002" sec-type="section"> <title>Methods</title> <p>We examined 21 arms from 11 nonembalmed cadavers with US. Under US guidance, we injected ink into the DBRN perineural sheath beneath the arcade of Frohse. In subsequent anatomical dissection we evaluated the distribution of the ink.</p> </sec> <sec id="mus24483-sec-0003" sec-type="section"> <title>Results</title> <p>It was possible to apply ink at the DBRN in 95%. In 80% the ink remained within the supinator and did not reach the DBRN segment proximal to the arcade.</p> </sec> <sec id="mus24483-sec-0004" sec-type="section"> <title>Conclusions</title> <p>With US guidance, it is possible to apply injection fluid safely around the DBRN inside the supinator tunnel. Due to the limited extent of the fluid, a second injection proximal to the arcade should be considered in the clinical setting. <italic>Muscle Nerve</italic><bold>51</bold>: 853–858, 2015</p> </sec> </abstract>
