Closed traumatic avulsion of both extensor carpi radialis tendons is report
ed in a young healthy patient. Early diagnosis important because the tendon
s tend to retract and anatomic repositioning is more difficult to perform w
ith passing time. Diagnostic markers are the inability to actively extend t
he wrist and the presence of dorsal bone fragments on the lateral radiograp
h of the wrist. We recommend fixation of the avulsed fragments to restore t
he length and strength of the wrist extensors. (J Hand Surg 1999;24A: 1286-
