Extensor pollicis longus tendon rupture following avulsion fracture of the third metacarpal.

摘要

Extensor pollicis longus (EPL) tendon rupture is a recognised complication of distal radial fractures and their fixation with dorsal radial plates and pins. A number of other conditions including internal fixation of wrist fractures and inflammatory arthropathies have also been reported as aetiological factors of EPL tendon rupture. We report a case of extensor pollicis longus tendon rupture following avulsion fracture of the third metacarpal and review the radiographic and sonographic features.
