Early osteolysis associated with trunion-liner impingement.
Osteolysis is perhaps the biggest unsolved problem in joint arthroplasty. Many factors contribute to osteolysis, some of which cannot be controlled. It is imperative to minimize controllable factors contributing to osteolysis whenever possible. We report four cases of trunion impingement on an elevated rim liner, which may have contributed to early aggressive osteolysis. Although the use of an elevated liner may result in a lower incidence of postoperative instability, the trade-off in using such a device must be understood.
