Abstract
Periprosthetic femur fractures are becoming more frequent, as the prevalence of hip
and knee arthroplasties keeps increasing and our population continues to age. Although
the vast majority of literature on periprosthetic fractures has centered on radiographic
and functional outcomes, only limited information is available on mortality. Patients
with periprosthetic femur fractures are at a similar or higher mortality risk than
hip fracture patients. Furthermore, periprosthetic femur fractures carry a significantly
higher mortality risk than hip or knee arthroplasty or operative fixation of native
distal femur fractures. Advanced patient age and underlying comorbidities increase
the risk of mortality. Factors related to the injury itself and treatment method may
play an additional role, especially during the short postoperative period.
