Surgical Treatment of Acetabular Fractures by Modified Stoppa Approach

Objective To evaluate the effect of the surgical treatment in acetabular fractures through modified Stoppa approach.Methods The clinical data of 72 cases of selective acetabular fractures treated in our hospital were studied retrospectively.Among them,41 cases received operations through single ilioinguinal approach,and 31 through modified Stoppa approach.Results The average time of operation was 125.4 minutes in group of single ilioinguinal approach,the average amount of intraoperative blood was 650 mL.1 case with infection,2 cutaneous nerve of thigh injury,1 ectopic ossification and 1 deep venous thrombosis(DVT) in pelvic limb were observed.The average time of operation was 85.8 minutes in group of modified Stoppa approach,the average amount of intraoperative blood was 410 mL,1 case with deep venous thrombosis(DVT) was observed.According to Matta standard,the excellent and good rate of reduction in single ilioinguinal approach group was 85.4%and 87.1% in modified Stoppa approach.The follow-up was 9~36 months,an average of 15.7 months.All the fructrues healed.The modified Merled′Aubigne and Postel score system showed that the joint functional fineness ratio was 82.9% and 83.9% in modified Stoppa approach group.There were not statistically difference in the excellent and good rate of reduction,the joint functional fineness ratio and the incidence rate of complication(P0.05),but in the average time of preoperation and amount of intraoperative blood(P0.01).Conclusion Because of the particular advantages of perfect exposure,minimally invasion,fewer complication and blood loss,modified Stoppa approach is one of the perfect operative approaches for acetabular fractures and can substitute for the traditional ilioinguinal approach in some cases.
