case_images: The ultrasonographic image taken on the day of the accident showed a complete EPL tendon rupture with a 4.31 cm gap in the right wrist (Fig. 1), and the magnetic resonance imaging (MRI) images taken 4 days after the accident also showed a complete tear of EPL tendon with a 5.6 cm gap in the right wrist (Fig. 2).
case_images: T2-weighted magnetic resonance imaging of the right hand. Complete tear of extensor pollicis longus tendon (A) Coronal view: no tendon in the gap (between 2 arrows) (B) Transverse view: no tendon in the expected course (arrow).

case_images: Thumb and wrist joints burden of the patient's tasks. Extension of the thumb and ulnar deviation of the wrist are thought to be burden on the extensor pollicis longus tendon. (A, B) Extension of the thumb: applying pressure while installing door trim and trunk garnish (C) Ulnar deviation of the wrist: holding the hand-arm vibration tool while injecting antifreeze liquid (D) Repetitive motion of the wrist: tightening a screw with the wrench while installing air cleaner, battery cable, and duct.
