Abstract:

Objective To compare the application effects of C-shaped forceps external fixation emergency technique and pelvic belt suspension traction technique in unstable pelvic posterior ring fractures. Methods A total of 80 patients with unstable pelvic posterior ring fractures were selected and randomly divided into the observation group and the control group, with 40 cases in each group. The control group was given pelvic belt suspension traction technique to fix pelvic fractures, while the observation group was given C-shaped forceps external fixation emergency technique to fix pelvic fractures. After fixation, pelvic X-ray examination was performed to evaluate the reduction quality of pelvic fractures in two groups. The emergency operation/surgery time, total blood transfusion volume and 2-hour shock index after surgery were recorded. The emergency effects (rebleeding rate, secondary injury rate, secondary surgery rate, rescue success rate and internal fixation surgery rate) were evaluated. The facial expression pain scale (FPS-R) was used to assess the degree of pain before fixation and 30 minutes after fixation. After 6 months of treatment, pelvic function was evaluated using the Pelvic Fracture Function Rating System (Majeed). Results The excellent rate of pelvic fracture reduction quality was higher in the observation group than that in the control group (75.0% vs. 55.0%, P<0.05). The secondary injury rate, internal fixation surgery rate and secondary surgery rate were lower in the observation group than those of the control group, and the success rate of rescue was higher than that of the control group (P<0.05). The emergency operation/surgery time, total blood transfusion volume and shock index were lower in the observation group than those in the control group (P<0.05). After 30 minutes of fixation, the FPS-R scores of both groups decreased compared to before fixation, and FPS-R scores of the observation group was lower than those of the control group (P<0.05). After 6 months of treatment, Majeed scores in both groups were increased compared to those before fixation, and there were no significant differences in Majeed scores between the two groups. Conclusion The emergency treatment of unstable pelvic posterior ring fractures using C-shaped forceps external fixation technique has shown good results and is worthy of clinical promotion and application.
