Sacroiliac Separation that Can be Diagnosed After Pelvic Fixation During Surgery: A Case Report and Review of Literature

Introduction: Sacroiliac joint separation is a life-threatening serious condition in pelvic injuries. It should be diagnosed early and treated properly. Although these injuries can often be detected by imaging methods, in some cases, it is not diagnosed. Case presentation: We report a rare case of pelvic injury with sacroiliac separation during surgery, while the sacroiliac joint was completely normal on X-ray and CT and no pelvic binder was used in the patient. The sacroiliac separation noticed during the operation was fixed with a sacroiliac screw. Conclusion: Pelvic injuries, especially ligament injuries, may not be detected on both physical examination, direct radiography, and CT.
