Complication related to orthopaedic hardware. Transverse (a, b) sonograms obtained from proximal (a) to distal (b) over the dorso-radial aspect of the distal radius in a patient with extensor carpi radialis brevis (ECRB) partial tear due to impingement on screws’ tips. In a, a screw tip is well demonstrated (black arrows) to be extruding from the cortex of the radius and penetrating the ERCB. In b, US shows a partial tear (white arrows) affecting the deep part of the tendon secondary to impingement on the screw’s tip. ECRL extensor carpi radialis longus
