Porous trabecular metal augments are uncemented hemispheric or elliptical components for the management of severe acetabular bone loss [1]. Based on the unique characteristics of trabecular metal, they can be used instead of structural allograft to reconstruct major acetabular bone defects [1]. They are made of porous metal tantalum or titanium alloys, and they are available in different shapes and sizes [2]. The basic shapes include the half-moon augments appropriate for minor column defects and the buttress augments with anterior of posterior columnar extensions to compensate for anterosuperior or posterosuperior acetabular defects [1, 3]. For superior segmental defects more than 30 mm above the acetabulum, a figure of seven augments may also be used [1].
