Diagnosis of a peritoneal injury during acetabular fracture surgery using the Stoppa approach: a case report

As the global population ages, acetabular fractures are increasingly diagnosed in older adults. These injuries, often caused by low-energy trauma, present treatment challenges due to reduced bone quality and the presence of comorbidities. Surgical fixation is frequently required to restore mobility and prevent long-term disability. In some cases, however, associated abdominopelvic injuries may remain occult until discovered intraoperatively. We report the case of a 67-year-old woman who sustained an acetabular fracture after a fall from height. During internal fixation using the modified Stoppa approach, an undetected peritoneal rupture was identified. This case underscores the importance of careful preoperative evaluation and preparedness for intraoperative collaboration with abdominal surgery teams, particularly when subtle abdominal signs are present.
