Background: Various fixation methods can be applied in sacroiliac injuries.Objective: To propose an alternative fixation method for sacroiliac joint injuries with a pre-contoured cloverleaf plate. Methods:We used a modified surgical technique with using a cloverleaf plate as a sacroiliac joint plate for treating a series of 7 patients with complex sacroiliac joint injuries in a single medical institute. The surgical technique was detailed described. Each patient was followed up with at the outpatient clinic after discharge at 2 weeks, 4 weeks, 12 weeks, and until bone union and pelvic ring stabilization.Results: All patients were followed up with for at least 6 months. There were no perioperative complications, such as nerve or vascular injury, a broken plate, loose screw and plate, and loss of reduction, due to the osteosynthesis operations. During the follow-up period, all fixations were maintained until early bone union. Conclusion:Fixation of a sacroiliac joint fracture with a cloverleaf plate is an alternative and new option that provides good fixation strength and economic efficiency.
