The "Double Washer" Technique Is an Effective Strategy for Bicortical Fixation in Periprosthetic Fractures About a Femoral Stem: A Technical Trick and Case Series.

SUMMARY:Periprosthetic fractures about the hip and knee are challenging injuries to treat for the orthopaedic surgeon. The pre-existing femoral implant and poor bone quality provide for difficulties in achieving stable fixation. We present a surgical technique and clinical series of 5 patients describing the use and outcomes of a 3.5 screw with a "double washer" technique to achieve bicortical fixation around a femoral prosthesis.
