Biomechanical Evaluation of Periprosthetic Femoral Fracture Fixation

Biomechanical Evaluation of Periprosthetic Femoral Fracture Fixation Downloaded from http://journals.lww.com/jbjsjournal by BhDMf5ePHKbH4TTImqenVA5KvPVPZ0P5BEgU+IUTEfzO/GUWifn2IfwcEVVH9SSn on 06/10/2020 COPYRIGHT  2008 BY THE JOURNAL OF BONE AND JOINT SURGERY,INCORPORATED Biomechanical Evaluation of Periprosthetic Femoral Fracture Fixation By Rad Zdero, PhD, Richard Walker, MD, James P.

Schemitsch, MD, FRCS(C) Investigation performed at the Martin Orthopaedic Biomechanics Laboratory, St. Michael’s Hospital, Toronto, and the Division of Orthopaedics, Department of Surgery, University of Toronto, Toronto, Ontario, Canada Background: A variety of methods are available for the fixation of femoral shaft fractures after total hip arthroplasty. However, few studies in the literature have quantified the performance of such repair constructs. The aim of this study was to evaluate biomechanically four different constructs for the fixation of periprosthetic femoral shaft fractures following total hip arthroplasty. Methods: Twenty synthetic femora were tested in axial compression, lateral bending, and torsion to determine initial stiffness, as well as stiffness following fixation of a simulated femoral midshaft fracture with and without a bone gap. Four fracture fixation constructs (five specimens per group) were assessed: construct A was a Synthes locked plate (a twelve-hole broad dynamic compression plate) with locked screws; construct B, a Synthes locked plate (a twelve-hole broad dynamic compression plate) with http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png The Journal of Bone and Joint Surgery Wolters Kluwer Health
