This paper reports the analysis of a modular S-ROM hip implant, which was retrieved at revision, secondary to aseptic loosening approximately after 24 months of implantation. Light microscopy and scanning electron microscopy confirmed the presence of pitting, fretting corrosion, plastic deformation, and stress induced corrosion cracking. Energy dispersive X-ray microanalysis of the stem surface revealed...
Clinical performance and microscopic analysis of a porous tantalum patella, retrieved from a 34-year-old male patient eight months after implantation is reported. The patellar component was sectioned and microscopically analyzed to determine the extent and characteristics of the soft tissue ingrowth. The metallic tantalum represented 20 vol.% of the analyzed patellar component. Large and small spherical...
