Pelvis fractures are common injuries with high morbidity and mortality rates. Appropriate fixation at the right time will reduce mortality and mortality, thereby improving long-term outcomes. The decision, planning, and execution of surgical treatment should be made by experienced surgeons who have received training. Extern fixation; today, it is used as a bridge treatment that reduces bleeding by decreasing the pelvis volume to increase the survival of the hemodynamically unstable patient rather than definitive treatment of adult pelvis fractures. The internal fixation ensures the continuation of anatomical reduction. It is biomechanically more stable and accelerates the rehabilitation process with early mobilization. Deciding which approach or approaches to use in treatment is at least as important as the surgical treatment decision. The most common complications are surgical site infections, reduction loss due to fixation failure, and mal-union.
