Finite element analysis of the stability of tibiofibular fractures treated with various combinations of external fixators

The external fixator should be configured to keep the crossbar as close to the skin as possible. For proximal tibial fractures, to minimize the use of external fixation components, the triangular cross-bar structure of Model B4 can be employed. In the case of distal tibial fractures, while the triangular cross-bar structure of Model C4 offers good stability, the risk of displacement is greater. Therefore, it is advisable to use an H-shaped fixation method with additional external fixation components, such as those found in Model C3.
