Mid-Term Results of 121 Periprosthetic Femoral Fractures: Increased Failure and Mortality Within but not After One Postoperative Year

Periprosthetic femoral fractures are associated with high failure rates and mortality, particularly within one postoperative year. However, mid-term results related to this issue are lacking. Thus, we performed a retrospective follow-up evaluation. Between 2007 and 2012, we treated a total of 121 consecutive patients for periprosthetic femoral fractures. After a mean of 57.2 postoperative months, we documented a total surgical revision rate of 16.5% within the first year, and the one-year mortality rate was 13.2%. Between one year and up to 7.3 postoperative years, only one surgical revision was necessary, and the mortality rate also decreased. No significant factors related to surgical revisions were detected. However, the initial hip fracture, older age, higher ASA score and dementia were associated with a higher mortality rate.
