Bilateral Avulsion Fractures of the Tibial Tuberosity: A Double Case for Open Reduction and Fixation

Tibial tuberosity fractures are rare and occur mainly in adolescent males during vigorous quadriceps contraction. So far, only ten simultaneous bilateral fractures have been reported. We report the case of a 16-year-old male who avulsed both tibial tuberosities when he landed on his feet after a gymnastics routine. Diagnostic imaging demonstrated Ogden Type IIIA fractures. He underwent bilateral open reduction and screw fixation with a good functional result after 3 months. While closed reduction and percutaneous fixation has been proposed by some, the intraoperative findings in our patient would have prevented correct adaptation of the fragments because of a flap of periosteum impinged in both fracture gaps. This case emphasizes that minimally invasive techniques may sometimes be inappropriate in the management of these types of fractures.
