[Bilateral traumatic elongation of the distal biceps tendon].

The rupture of the distal biceps brachii tendon involves characteristic functional deficits and clinical findings that allow easy diagnosis. Well-established surgical techniques will usually largely restore strength of flexion and supination. Lacerations without complete disruption of the tendon, however, pose diagnostic problems due to the absence of the typical gap in the course of the tendon. Our case of a bilateral traumatic elongation of the distal biceps brachii tendon demonstrates the value of clinical history, physical and sonographical examination that lead to the accurate diagnosis and adequate surgical treatment of this rare injury.
