Purpose: To evaluate the effectiveness of iliosacral screw fixation with anterior plating in the management of an unstable pelvic ring injury.
Materials and Methods: Nineteen patients with an unstable pelvic ring injury were enrolled in this retrospective study. All patients were followed up for at least 1 year. The mean age of the patients was 43 years. According to the AO-OTA classification, there were five B2 injuries, 11 C1 injuries, and 3 C2 injuries. After anterior fixation by plating, ilio-sacral screw fixation was performed percutaneously under the C-arm guide.
Results: All cases united except for 1 case of nonunion at the pubic ramus. The radiology results showed 9, 7, 2 and 1 case of anatomic, nearly anatomic, moderate and poor reduction, respectively. Sixteen out of 19 patients had a good or excellent functional result. Two moderate and one poor result were from an unsatisfactory reduction in a type C injury with the residual neurological signs. Screw misplacement with neurological compromise occurred in one patient but there were no adverse sequelae after its removal. Regarding the complications, there were two cases of screw loosening, two cases of anterior metal failures, and 1 case of a deep infection.
Conclusion: Percutaneous ilio-sacral screwing with anterior plating may be a useful method for treating unstable pelvic ring injuries, and the reduction quality and neurological signs are important.
