Case 1. A 22 year old male fractured his lower leg when landing on a baseball court. On that day after the diagnosis of open lower leg fracture we executed osteosynthesis with an interlocking nail (Gustilo type II, A0 type A3). Case 2. A 37 year old female fractured her lower leg when falling on a badminton court. On that day we executed irrigation and debridement after the diagnosis of lower leg open fracture (Gustilo type II, A0 type A1). 17 days after the first operation we executed plate osteosynthesis.
Discussion. In a gymnasium players occasionally lose their balances. To prevent falling to the court, a strong force between the sole of their sports shoes and the court may be transmitted to the bone causing fracture.
This report describes 2 cases of an open fracture of the lower leg due to indirect forces, and a discussion about the generation of indirect forces from the interaction of the sole of a sports shoe with the gymnasium floor.
