Biocompatibility for a tissue-sparing procedure

Just as in THA bearing couples, ceramics could be the (bio)logical alternative for hip resurfacing, too: It is the only material in hard-on-hard bearings proven in arthroplasty that does not release toxic metal ions. Currently, two ceramic-on-ceramic hip resurfacing systems are being tested clinically for safety and efficacy.

BIOLOX®delta ceramics failed to stimulate immunological responses

With the increasing use of composite ceramic bearings in THA, a group of researchers led by Joanne Tipper investigated the biological impact of BIOLOX®delta particles. The ceramic particles failed to stimulate an inflammatory response, and did not cause any DNA damage or oxidative stress in human cells in clinically-relevant doses.

Sleeved Ceramic Heads: Versatile, Essential and Proven

In hip revision, the metal taper of an otherwise intact and well-fixed stem can exhibit varying types of damage which may be attributed to assembly or disassembly damage as well as black debris indicating fretting or even corrosion. Depending on the grade of the taper damage, the use of a sleeved ceramic head can offer a possibility to retain a well-fixed stem.
