[Bilateral tibial head epiphysiolysis in somersault jumping]

We are reporting about a rare case of a bilateral epiphyseal separation of the proximal tibial epiphysis which occurred to a 16 year old male at the time of bileged take-off when somersault diving. The X-rays at admission showed a bilateral proximal tibial epiphyseal separation of Salter-Harris type I on the right side and Salter-Harris type II on the left side. Both epiphyses showed a posterior dislocation. Stable, anatomical position on both sides was achieved by closed reduction under general anaesthesia and fixed by a plaster cast for five weeks. Healing occurred in anatomical position and no redislocation or growth disturbance was observed. The treatment for such separations is usually conservative; the prognosis is very good, provided that an optimal reposition with restoration of the anatomical situation has been achieved.
