Matta's Arc: Relevant or Not?

Abstract

Matta's Roof Arc Angle (RAA) is utilised to evaluate the load-bearing dome in cases of acetabular fractures, assisting clinicians in making informed decisions regarding treatment options through the measurement of angular displacement. This assessment is crucial for the assessment of acetabular coverage and the stability of the femoral head, helping to determine whether surgical intervention or non-operative approaches are more suitable. Nevertheless, the variability of this method underscores the importance of incorporating additional criteria to ensure the best possible clinical outcomes for patients.
