Comparison of Surgical Results of Modified Stoppa and Ilioinguinal Approach in Patients with Acetabular Fractures Involving Quadrilateral Surface Fractures.

Objectives: The aim of this study was to evaluate the results of surgical treatment in patients with acetabular fractures with a fractured quadrilateral surface treated using two different approaches.

Methods: The study included 106 patients who were operated on with ilioinguinal (group A) or modified Stoppa (group B) technique for acetabular fracture with a fractured quadrilateral surface between 2011 and 2020 in our clinic. The quality of reduction was evaluated according to Matta criteria and postoperative pelvic (anteroposterior, external oblique, iliac oblique) radiographs. Evaluation of hip function was recorded using the Merle d'aubigne and Postel Score and Harris Hip Score.

Results: Among the patients included in the study, there were 45 patients in group A and 61 patients in group B. When the group data were compared, it was seen that the modified Stoppa approach was superior in terms of intraoperative reduction quality, radiological data, Harris hip score, Merle d'aubigne and PostelScore. (Respectively p=0.40, p=0.49, p=0.040, p=0.028).

Conclusion: : Modified Stoppa approach has successful clinical and radiological outcomes and better reduction quality and hip scores than ilioinguinal approaches in acetabular fractures involving quadrilateral plates.
