Registries look at cancer, PJI and fracture

isar_2017_congress_report.pdf

Cancer, PJI and periprosthetic fracture were the main subjects discussed at the Sixth International Congress of Arthroplasty Registries (ISAR) held May 20-22, 2017, in San Francisco, USA. According to the Australian registry, the overall incidence of cancer for THA patients was 6% higher than the population average. The authors did not find a significant difference in all-site cancer rates between metal-on-metal (MoM) and other bearings. Nevertheless, the incidence of Hodgkin’s Lymphoma was 117% higher with MoM.

PJI remains one of the most frequent reasons for failure in THA worldwide, according to the authors of an international registry collaboration study. The British National Joint Registry (NJR) shows an increased risk of revision for PJI in males, smokers and patients with high BMI, diabetes, rheumatoid arthritis, chronic pulmonary disease or liver disease. The authors also identified an influence of dementia, fractured neck of femur, previous history of infection and lateral surgical approach. There was no evidence of association with the presence of a consultant (none, assisting, operating), grade of operating surgeon (consultant, other) and place of surgery (England, Wales). Ceramic bearings showed a protective effect against PJI.
