Comparison of Functional Outcome of Modified Stoppa Approach versus Ilioinguinal Approach in Fixation of Acetabular Fractures: An Observational Study

Background: Acetabular fractures are complex injuries typically resulting from high-energy trauma such as road traffic accidents. Surgical fixation with anatomical reduction is the cornerstone of treatment. The Modified Stoppa approach has emerged as an alternative to the traditional Ilioinguinal approach for anterior acetabular fractures.

Objective: To compare functional outcomes, complications, and operative parameters between the Modified Stoppa and Ilioinguinal approaches in acetabular fracture fixation.

Methods: An observational comparative study was conducted at Sir T Hospital, Bhavnagar, including 30 patients with displaced acetabular fractures treated surgically between 2022 and 2024. Patients were divided into two groups: Modified Stoppa approach (n=15) and Ilioinguinal approach (n=15). Functional outcomes were assessed using the Harris Hip Score and the Modified Merle d’Aubigné and Postel scoring system.

Results: Most patients were males (90%) with a mean age of 45.6 years. Road traffic accidents were the most common cause (73%). Both approaches showed good to excellent functional outcomes in most cases. Excellent results were achieved in 40% of patients in both groups according to the Merle d’Aubigné scoring system. Good outcomes were observed in 46.7% in the Ilioinguinal group and 53.3% in the Modified Stoppa group. Average hospital stay was shorter in the Modified Stoppa group (7 days) compared to the Ilioinguinal group (13 days).

Conclusion: The Modified Stoppa approach provides comparable functional outcomes to the Ilioinguinal approach while reducing surgical morbidity and hospital stay.
