Case: This case report discusses 2 cases of proximal femur peri-implant fractures after the use of lateral locking plates for distal femur periprosthetic fractures.
Conclusion: The use of locking plate technology for fixation of distal femur periprosthetic fractures is a common treatment modality. Although much has been reported regarding healing and complication rates of distal femoral periprosthetic fractures, little has been reported about peri-implant fractures subsequent to treatment using locking plates. We propose the importance of developing a method of fixation to protect the entire femur in osteoporotic patients sustaining distal femur periprosthetic fractures at the index surgery to avoid this complication.
