    Our hypothesis was that a tantalum trabecular metalsurfaced acetabular cup would give a higher degree of fixation over a larger area, leading to better initial stability. We designed a randomized radiostereometric analysis (RSA) trial comparing the tantalum trabecular metalsurfaced acetabular cup with a titanium fibermesh surface cup. The primary end point was cup migration within the ...

    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 6year period. There were 29 Paprosky type 3A defects and 9 Paprosky type 3B defects. The mean age of the patients at the .
