Ulnar nerve dislocation at the elbow: the role of ultrasound

We have read with attentiveness the case “Ultrasonography Detects Ulnar Nerve Dislocation Despite Normal Electrophysiology and Magnetic Resonance Imaging” by Pisapia et al.1 The paper describes the interesting case of a young patient with ulnar nerve dislocation at elbow in whom electrophysiological and magnetic resonance (MR) findings were normal. In this case, ultrasound (US) found nerve dislocation over the medial epicondyle, which was confirmed by surgical exploration. The manuscript provides useful information for physicians. The case presentation and its management are very clear and very didactic. The significance of a correct clinical evaluation, as described by the authors, is high. This evaluation, in fact, allows formulating a diagnostic suspicion and deciding the best further course.
