A possible mechanism of direct injury to the EPL tendon at Lister's tubercle during falls with the wrist fully extended.

摘要

We present three cases of pathology of the extensor pollicis longus tendon at the level of Lister's tubercle after falls with the wrist fully extended. A small anatomical study demonstrates the possibility of the base of the third metacarpal impacting this area in hyperextension. This mechanism of injury to the tendon may explain the clinical findings.
