Introduction:
Periprosthetic fractures of the femur are uncommon, but at times may lead to complications especially in elderly patients. As treatment of these fractures is difficult, prevention by identifying the risk factors is the best way to overcome these complex problems.
Case report:
A periprosthetic right femur fracture associated with a neglected left femoral neck fracture in the contralateral femur in a 78-year-old elder woman patient is reported in the present article. We discuss the prevention of periprosthetic fractures after hip arthroplasty and address the risk factors associated with this complication.
Conclusion:
The present case emphasizes the importance of investigating and treating the cause of sudden onset of restriction on full weight-bearing in the contralateral limb, to prevent periprosthetic femoral fracture after hip arthroplasty in elderly patients.
