[Osteochondral fracture of the lateral tibial pilon].

In this paper we report a case of osteochondral fracture of the lateral tibial pilon. A young man fell while he was playing soccer. In the following months the ankle was swollen and painful. Later the reason for his ankle pain was clearly visible on the X-ray pictures, which revealed a severe osteochondral fracture of the lateral tibial pilon. We describe the arthroscopic and X-ray grading of osteochondral fractures of the ankle and their treatment.
