Loosening of a Total Hip Arthroplasty Associated with a Periprosthetic Femoral Fracture Caused by Recurrent Hydatidosis of the Hip: A Case Report.

CASE: A 35-year-old woman, who lived in an endemic area for echinococcosis, developed a periprosthetic fracture with loosening of a total hip arthroplasty that had been performed 9 years earlier for hydatidosis of the right proximal femur with a pathological femoral neck fracture. At that time, the patient did not have any signs of liver or lung involvement. She was successfully managed by a cemented revision hip arthroplasty without any signs of recurrence at the last follow-up of 5 years.

CONCLUSIONS

Total hip arthroplasty can offer effective management of proximal femur hydatidosis, despite the high rate of recurrence and mechanic failure.
