Traumatic avulsion of the triceps brachii.

Traumatic avulsion of the triceps brachii tendon is a rare injury. Clinical diagnosis shows that elbow extension against gravity is not possible. Radiologically, the lateral elbow may show the presence of flecks of avulsed osseous material from the olecranon ("flake sign"), which is almost pathognomonic of this lesion. The authors of the present study present a case of avulsion fracture treated with the attachment of bone suture anchors.
