Triggering due to de Quervain's disease is exceedingly rare. This is the first successfully diagnosed case of the snapping phenomenon of the extensor pollicis brevis (EPB) tendon in de Quervain's disease evaluated with preoperative dynamic ultrasonography, clearly demonstrated in an intraoperative video, and treated with decompression of EPB subcompartment only under a wide‐awake surgery. Dynamic ultrasonographic images identified snapping caused by unsmooth excursion of an enlarged EPB tendon in a separate subcompartment. In snapping de Quervain's disease, ultrasonographic evaluations and wide‐awake surgery are essential to exactly diagnose and successfully treat the snapping condition of the EPB and/or APL tendons.
