Periprosthetic Supracondylar Femoral Fractures Above a Total Knee Replacement: An Updated Compatibility and Technique Guide for Fixation With a Retrograde Intramedullary Nail.

Background: Multiple studies have described retrograde nailing as a treatment of periprosthetic supracondylar femoral fractures (OTA/AO type 33A-C) above total knee replacements (TKRs). It is often difficult to discern which TKRs will be compatible with intramedullary nailing because the femoral component design and intercondylar distance is highly variable among total knee designs. The goal of our study is 3-fold: (1) Review and update previous work of intercondylar distances of all currently available prostheses in the United States.

Patient Mortality in Geriatric Distal Femur Fractures.

Objectives: To estimate 1-year mortality rates in elderly patients who undergo operative treatment for distal femur fractures and identify potential risk factors for mortality.

Design: Retrospective chart review.

Setting: Level 1 and Level 2 trauma centers.
