BIOMECHANICAL FIXATION STRENGTH COMPARISON OF ILIOINGUNIAL AND MEDIAL STOPPA APPROACHES ON ANTERIOR COLUMN FRACTURES

Background: Both the ilioinguinal and Stoppa approaches have been used as standard methods for treating anterior column fractures of the pelvis. Objective: We aimed to compare the rigidity of pelvises that were treated using these two approaches. Methods: Fifteen synthetic pelvises were used as test models. Of these, 5 pelvises did not undergo any treatment (control group), and 10 pelvises underwent treatment of one column using the ilioinguinal approach and the other using the medial Stoppa approach (treated group). The compression test was performed on all pelvises, and rigidity of the pelvises was compared between the control and treated groups. Results: A statistical difference was found in the angle between the center of the femoral head and the line from the pubic symphysis to load application between the control and treated groups, using the ilioinguinal approach. The parametric displacement was greater in the treated group using the ilioinguinal approach than in the control group. There were no significant differences between the control and treated groups using the Stoppa approach, and the ilioinguinal approaches. Conclusion: Clinically, the Stoppa approach has several advantages over the ilioinguinal approach. However, based on the compression test, there was no difference in biomechanical rigidity between the fixations performed using these two approaches.
