Acetabular Revision Using Trabecular Metal Augments for Paprosky Type 3 Defects.

Background: Trabecular Metal (TM) augments are one option when reconstructing bone loss during acetabular side revision surgery.

Methods: We studied 38 consecutive patients with Paprosky type 3 defects that were revised using a TM shell and one or more augments over a 6-year period. There were 29 Paprosky type 3A defects and 9 Paprosky type 3B defects.
