Abstract

Porous tantalum acetabular implants provide a potential solution for dealing with significant acetabular bone loss. This study reviews 24 acetabular revisions using tantalum implants for Paprosky type 3 and 4 defects. The mean Harris Hip Score improved from 35±19 (range, 4-71) to 88±14 (range, 41-100), p<0.0001. Postoperative radiographs showed radiolucent lines in 14 hips with a mean width of 1.3±1.0mm (range, 0.27-4.37mm). No gaps enlarged and 71% of them disappeared at a mean of 13±10months (range, 3-29months). At a mean follow-up of 37±14months (range, 24-66months), 22 reconstructions showed radiograpic evidence of osseointegration (92%). The two failures were secondary to septic loosening. When dealing with severe acetabular bone loss, porous tantalum acetabular components show promising short-term results.
