Learning objectives

-To review the different types ofPeriprosthetic Femoral Fractures in hip and knee replacement. -To illustrateimportant findings which should be described in periprosthetic fractures reporting in order to give the surgeon adequate information.

Background

Hip and knee replacement have become frequent surgeryand periprosthetic fractures are one of the most frequent and important complications. Thus, knowledge of imaging findings and parameters which should be evaluated in periprosthetic fractures is importantinradiological evaluation of hip and knee replacement.

Findings and procedure details

Periprosthetic fracture (PF) is a term used to describe any fracture that occurs around an implanted orthopedic prosthesis, most commonly knee or hip arthroplasties. Periprosthetic fractures complicate 1-4% of total hip arthroplasties and 1.5-3% of total knee arthroplasties PERIPROSTHETIC HIP FRACTURES A periprosthetic fracture is a serious complication that most often requires surgery. PF is an increasingly common complication associated with THA, occurring in 1-4.1% of primary THAs and at higher rates following revision THAs. Fractures occur more often around the femoral than the acetabular...

Conclusion

It is important for the radiologist to be aware of signs indicating periprosthetic fractures in order to avoid delays in patient treatment. However, they can be difficult to diagnose, with metalware potentially obscuring the fracture on x-ray or creating extensive artifact on CT/MR.
