Clinical and Radiological Early results of Acetabulum Fractures Operated with the Modified Stoppa Approach

Aim: To evaluate the follow-up results of patients hospitalized for acetabular fractures and treated with the modified Stoppa approach. Methods: Records of fifty-two Acetabula from 48 patients who were followed up for at least six months between 2016 and 2019 were retrospectively analyzed. All fractures were classified according to the Judet-Letournel classification along with direct X-rays and 3D computed tomography findings. The postoperative reduction quality and radiological assessments during follow-up visits were evaluated according to Matta's reduction quality criteria and Matta's radiological scoring system. The clinical outcomes were analyzed using the modified Merle d'Aubigne scoring system. Results: The mean follow-up period of 48 patients included in the study was 9.72 (6-26) months. Excellent clinical results were obtained in 38 acetabula (73%). A significant correlation was found between the reduction quality assessment performed on the postoperative X-rays and the clinical outcome (p=0.002). At the same time, there was a significant correlation between Matta's radiological criteria and clinical outcomes (p<0.001). Conclusion: This study shows that reduction quality in acetabular fractures and anatomical reduction done with stable fixation under optimal conditions is strongly associated with clinical outcomes.
