Pelvic injuries are usually encountered in patients with polytrauma. These are injuries that need to be treated with a multidisciplinary approach. The primary approach is to stabilize the patient hemodynamically. Mortality rate in pelvic injuries reaches 10-20%.~The pelvis has a ring-shaped structure. It is the sacrum that transfers the load from the lower extremities to the axial spine from this structure. The joint between the sacrum and the ilium, that is, the joint that is exposed to the load, is the sacroiliac joint. For this reason, surgical treatments have been developed to stabilize the posterior pelvic ring, to mobilize the patient as soon as possible, to walk in a balanced way without leg length difference, to prevent loss of work force, and to shorten the hospitalization period. Open reduction internal fixation and closed reduction percutaneous sacroiliac screw fixation surgical methods have been described to ensure the stability of the posterior pelvic ring In this study, we evaluated the radiological and functional results of patients with posterior pelvic ring injuries stabilized by open and closed surgical approaches; We have compiled and summarized the current literature on pelvic injuries. We aimed to contribute to the literature by sharing our knowledge and findings about these difficult, complex and prone surgical techniques.~marks of conformity~Surgical intervention for sacroiliac joint fracture-dislocation~18-65 years old patient~Patients who come to clinical follow-ups for at least 6 months
Surgical trearment of unstable posterior pelvic injuries can be performed with open reduction and internal fixation, closed reduction with percutaneous sacroiliac fixation. Biomechanically, no significant difference was found between the two methods in the literature. The aim of our study is to compare the radiological and clinical functional results of these methods.
