Abstract
Pelvic fractures, usually are multiple, unstable fractures occuring most frequently due to violent traumatic events. Orthopedic treatment of these lesions is often distressing both to patients and medical personnel since it requires bed discharge or sometimes tractions which can have a duration up to 45 days and can compromise the static and the walking mechanisms; open operative management is difficult, carrying a significant burden in terms of morbidity and associated with vascular (venous plexus), nervous (sacred roots) or septic risk to take into account. For this reason it is generally reserved for patients with neurologic and strongly displaced forms. Percutaneous fixation under fluoroscopy in unstable type B and type C pelvic fractures allows the synthesis of posterior lesions causing instability by fixing the hip bone to S1 or S2 body, a rapid recovery and rehabilitation of walking.
