Management of severe open and segmental tibial fractures with type Ⅳ inlaid external fixator

Using mosaic external fixator to treat the complex fracture of tibia and fibula;

Inlaid external fixator for treatment nonunion of the femur associated with traumatic-infection;

The biomechanical study on the treatment of pelvis fracture and dislocation using trapezoid external fixator;

Objective: The purpose of the study was to evaluate the better way between dynamic compression plate and AO external fixation, using in atrophic humeral shaft nonunion, at the same time, the atrophic humeral shaft nonunion can be applied to the two above-mentioned fixation ways.
