Computer navigated percutaneous screw fixation for traumatic pubic symphysis diastasis of unstable pelvic ring injuries

摘要

Displaced and unstable pelvic ring injuries have been treated mainly by open reduction and internal fixation. The goal of treatment relies on restoration of pelvic anatomy with stable internal fixation, allowing early mobilization of the patient.1,2 The symphysis pubis dislocation (>25 mm) is consistent indication for anterior internal fixation.3 In most situations, the fixation of the displaced symphysis pubis requires extensive exposure, which may lead to complications including blood loss, neural or vascular injury, postoperative infections, wound healing problems and heterotopic bone formation.
