Avulsion of both extensor carpi radialis tendons: a case report.

Closed traumatic avulsion of both extensor carpi radialis tendons is reported in a young healthy patient. Early diagnosis important because the tendons tend to retract and anatomic repositioning is more difficult to perform with passing time. Diagnostic markers are the inability to actively extend the wrist and the presence of dorsal bone fragments on the lateral radiograph of the wrist. We recommend fixation of the avulsed fragments to restore the length and strength of the wrist extensors.
