Fig. 1 Ultrasound of the right elbow showing (A) the posterior interosseous nerve (PIN) (long arrow) proximal to anchor and between the 2 heads of the supinator muscle (one head seen between arrow heads); (B) enlarged PIN (shown between large arrows) of 6.8mm diameter (dotted line) as it approaches anchor; (C) anchor through the course of PIN (encircled); (D) PIN distal to the anchor (long arrow). (E) Lateral and AP Xray views of the right forearm and 2 biceps anchors with distal anchor appearing to protrude through posterior aspect of radius (arrow head). (F) Schematic depiction of biceps tendon anchors, with anchor morphology shown in the top right corner [4]. eNeurologicalSci  2017 8, 34-35DOI: (10.1016/j.ensci.2017.07.002) Copyright © 2017 The Authors Terms and Conditions
