Background and Objectives: The potential association between implants and m
alignancy has been discussed in the literature, but never as a cause of loo
sening of joint arthroplasty.
Methods: The records of all patients who underwent revision arthroplasty at
our institution between 1992 and 1995 were reviewed.
Results: Among 93 patients who underwent revision hip arthroplasties, I I (
11.8%) had a history of previous malignancy. At surgery, in 2 of these pati
ents, metastasis was found to be the cause of loosening in the affected hip
Conclusions: When revision hip arthroplasty is considered, patients with a
history of malignancy require attenuated pre-, intra-, and postoperative wo
rkup. Management algorithm in such cases is proposed. (C) 1999 Wiley-Liss,
