modular or revision porous tantalum metal shell) was then ﬁrmly impacted against the native bone and the PMMA-covered portion of the augment. The revision porous tan-talum shell offers the theoretical advantages over the modular component of a lower modulus of elasticity, increased ability to obtain screw ﬁxation by drilling
Mar 25, 2013· The Trabecular Metal Augment and Restrictors from Zimmer are a selection of structural augments intended for revision or difficult primary hip reconstructions associated with significant bone loss. This is part of the Zimmer TMARS (Trabecular Metal Acetabular Revision System).
Trabecular metal has been proposed in revision TKA because of its properties, such as increased osteointegration and structural stability. Tantalum cones can be a viable option to treat severe type 2 or 3 bone defects and can be used in association with tantalum augments to increase primary fixation .

Porous tantalum acetabular cups and augments were introduced to improve biological fixing and restore the normal centre of rotation. The greatest advantage is for major bone defects, where the tantalum cup and augments provide stable primary fixing with the biological potential for bone ingrowth.
The revision acetabular shell was used in 15 sion with porous tantalum acetabular components and reconstructions when the surgeon believed the bone quality modular augments for Type IIIA acetabular defects during was particularly poor, additional screw fixation was the aforementioned time period.
Oct 16, 2008· Abstract. Large acetabular defects can be reconstructed with various methods depending on size and location of the defect. We prospectively followed our first 37 patients in whom we reconstructed the acetabulum with a trabecular metal augment combined with a trabecular metal shell.

The use of a trabecular metal acetabular component and trabecular metal augment for severe acetabular defects.
one or more acetabular tantalum augment was necessary to fit the defect and stabilize the trial. The augment could be inserted in many variable loca-tions according to the bone loss pattern. Augments are often placed on the medial aspect of the ilium and are commonly used with the wide base placed laterally and the apex medially in type IIIB and in
Early rEsults of traBEcular mEtal augmEnt 531 Modular porous trabecular metal (tantalum) aug-ments were recently developed to achieve biologi-cal fixation and provide coverage and mechanical support for an uncemented hemispheric acetabular component. These cups and augments are manufac - tured in multiple sizes and shapes to accommodate

The potential for biologic fixation with the use of a trabecular metal acetabular component and augment may also provide improved long-term outcomes, unlike the use of a cage, which is subjected to nonbiologic fixation and the potential for fatigue failure 13, 14. The material properties of trabecular metal are ideal for acetabular revision.
