Simulated Weight Bearing and Articular Injury From Transarticular Screws In A Lisfranc Injury Model:

摘要

Category:Midfoot/Forefoot, TraumaIntroduction/Purpose:Successful treatment of Lisfranc injuries, relies upon anatomic reduction [1-3] and rigid fixation until bony or ligamentous healing has occurred and inherent stability has been restored. Historically, transarticular screw fixation has been the most common method of fixation, but optimal treatment remains controversial.Articular injury from transarticular screw fixation may lead to arthritis of the Lisfranc joints and future morbidity. To our knowledge only two studies have evaluated articular injury from transarticular screws [6,7]. Neither of these studies, and no other study to our knowledge has investigated relative increase in articular damage after simulated weight bearing.The aims of this study were: (1) create a ligamentous Lisfranc injury model and (2) compare relative increase in articular injury pre- and post-simulated weight bearing from screw toggle.Methods:10 cadaver specimens underwent transarcticular screw fixation with 3.5 mm cortical ...
