Case: We present a case of a 54-year-old man with atraumatic, U-type sacral insufficiency and L5 compression fractures leading to spinopelvic dissociation, inability to ambulate, and bowel/bladder compromise. The patient underwent L3-4 percutaneous pedicle screw fixation with bilateral iliac bolts and percutaneous iliosacral screw fixation. Postoperatively, the patient had return of bowel/bladder function and independent ambulation at 2.5 years.
Conclusion: Atraumatic spinopelvic dissociation is an underappreciated pathology in older patients. Here, we describe the result of our preferred treatment strategy, triangular osteosynthesis, to preserve function and independence. Despite optimal, prompt treatment, these injuries pose a difficult rehabilitation process for patients.
