Acetabular fractures are potentially severe fractures associated with high morbidity and disability. Although open reduction and internal fixation are the standard methods of treating displaced acetabular fractures, open reduction has substantial morbidity, such as blood loss, neurovascular injury, wound infection, wound healing problems and heterotopic bone formation. With the development of advanced radiologic technology and new techniques and approaches for reduction and internal fixation, a percutaneous approach for internal fixation has become possible. Percutaneous approach is associated with fewer complications related to surgical exposure. It is a possible treatment option with no or minimal displaced, but instable acetabular fractures with a risk of secondary displacement, and displaced acetabular fractures which can be reduced by cannulate screw.
