Plain English summary of protocol
Background and study aims
Pelvic fractures, especially the unstable pelvic fractures, are associated with massive hemorrhage or important organ injuries resulting in significant morbidity (disease) and mortality (death). The early reduction (a type of surgical procedure to try and fix the fracture) for the unstable pelvic fractures has been considered to be effective to improve the clinical results. However, the optimal early reduction technique for the unstable pelvic fractures remains controversial. This study uses a computer aided system to help treat the unstable fracture. The aim of this study is to verify the effectiveness and report early experience with reduction of the unstable pelvic fractures using a computer aided pelvic reduction frame.
Who can participate?
Adults aged 18 and older who have unilateral unstable pelvic fractures and displacements.
What does the study involve?
Participants undergo surgery for their unstable pelvic fracture using a computer aided reduction frame. Participants also undergo a CT scan (a type of imaging that uses x-rays to create a detailed image of the body) during the procedure to see the reduction quality. Based on this scan, a pelvic model is reconstructed and the differences between the model and the actual pelvis are calculated. The reduction precision of the fracture is measured and any complications are recorded.
What are the possible benefits and risks of participating?
The direct benefit for the patients taking part in the study include low complications rates, smaller incisions of the operations, and shorter rehabilitation period. The direct risks for the patients include higher radiation exposure from intraoperative CT scan.

| Ethics approval(s) | Institutional Ethical Review Committee of Chinese PLA General Hospital, 01/01/2015 |
| Health condition(s) or problem(s) studied | Unstable pelvic fracture |
| Intervention | This study is a prospective single-group interventional study. All the participants in this study are allocated to the treatment group. All participants undergo the surgery of unstable pelvic fracture using a computer aided reduction frame. For evaluation of the reduction quality of the clinical application of the entire system, this series of patients are performed with a second intro-operative CT scan after reduction with the frame. Based on this second intro-operative CT scan data, the 3D pelvic model at the anatomical reduction position can be reconstructed. The residual translational and rotational differences between the actual and virtual anatomical reduction positions could be calculated. The operation time is also recorded for the quality control of this technique. Participants receive the standard post surgical care. |
| Intervention type | Procedure/Surgery |
| Primary outcome measure(s) | 1. The reduction precision of the unstable pelvic fractures is measured using the residual translational and rotational differences between the actual and virtual anatomical reduction positions of pelvis at the end of operations 2. The intra-operative complications, such as wound infection, nerve or vascular injury, are recorded and retrieved from the medical electric records after the operations |
| Key secondary outcome measure(s) | The mean duration for the setup of the frame, the virtual surgery simulation, and the reduction of the unstable pelvic fractures, were recorded by our researchers during operations. |
