Abstract: Objective　To study the applied value of high ilioinguinal approach in the clinical treatment of Tile C type pelvic fractures. 　Methods　In this study, 35 patients with Tile C type pelvic fractures were selected as subjects of group A, which were treated by high ilioinguinal approach, while other 35 patients with Tile C type pelvic fractures were selected as subjects of group B, which were treated by simple posterior approach. After the treatment, the excellent and good rate, satisfaction rate, intraoperative blood loss, incision length, operation time, length of stay, time of hospitalization and incidence of complications were compared between the two groups. 　Results　In terms of excellent and good rate, group A was 88.57%, group B was 65.71%, group A was higher than group B (P<0.05). In terms of satisfaction rate, group A was higher than that of group B (P<0.05) (Group A was 97.14%, group B was 74.29%). The volume of intraoperative blood loss, the length of incision, the time of operation, the time of going to the ground and the time of hospitalization in group A were all lower than that in group B (P<0.05). In terms of the incidence of complications, group A was 2.86%, group B was 22.86%, thus group A was lower than group B (P<0.05). Conclusions　In the treatment of Tile C type pelvic fractures, the treatment with the high ilioinguinal approach has the advantages of significant effect and high safety, so it has a high clinical application and promotion value.
