Management of radiation induced, bilateral Primary THA loosening with an aseptic Paprosky Type IIB acetabular defect and a contralateral septic Type IIIB acetabular defect: A case report and review of literature

摘要

Introduction Primary THA in an irradiated hip poses risk for early loosening and inadequate ingrowth.Adverse effects such as decreased vascularity and increased infection risk pose a threat. Case presentation Our patient was a case of post-irradiation (for cervical cancer) bilateral THA loosening causing aseptic acetabular loosening on one side and catastrophic septic loosening with a Paprosky type IIIB acetabular defect with pelvic discontinuity on the contralateral side. Discussion There have been various studies documenting deleterious effects of irradiation on osseointegration and provide a challenge for long-term implant stability in THA patients. Conclusion A meticulous treatment protocol with contemporary implant technology and staged bilateral stepwise management can lead to satisfactory clinical outcomes.This case report highlights on such specific nuances and principles.
