Mittal A, et al. - This study was undertaken to investigate outcomes of interprosthetic femoral fractures (IFFs) managed with modern distal femoral locking plates, in a larger sample size than previously published. Researchers designed a retrospective study examining 49 closed IFFs in 48 patients at a major trauma center from 2009 to 2019 occurring between previous total hip arthroplasty (n=38), hemi hip arthroplasty (n=3), dynamic hip screw (n=6), or cephalomedullary nail (n=2) and total knee arthroplasty. The results demonstrate that IFFs are occurring with elevating frequency in a frail elderly population. Using modern distal femoral locking plates, MIPO and biological fixation techniques can achieve a high rate of the union when combined with immediate unrestricted weight-bearing postoperatively in patients with IFFs.
