[Anterior tibial tubercle fracture in teenagers. Clinical cases].

INTRODUCTION

Anterior tibial tubercle fractures are relatively infrequent and occur mainly in young athletes 14 to 17 years old. Most fractures result from jumping during sports activities.

METHODS

We describe two cases of anterior tibial tubercle fractures. The latter were Ogden IIIA and IIIB. In both cases treatment consisted of open reduction and internal fixation with cannulated screws.

DISCUSSION: The mechanism of injury in the first case is more common than the one in the second case. The first case occurred after jumping to receive a pass during a basketball game. The second one occurred while playing soccer. The patient was kicked on the quadriceps musculature. Both cases involved functional disability.

CONCLUSION

Biomechanically, the mechanism of injury in the second case increased the tension on the extensor apparatus. We performed synthesis with cannulated screws and obtained good results without complications.
