【 摘 要 】

Category:Ankle ArthritisIntroduction/Purpose:Pre-operative templating using plane radiographs is of great importance in planning arthroplasty of the hip and knee. Its role in total ankle arthroplasty (TAR) is less clear. Being able to use the best fitting implant is of paramount importance for transferring forces through the ankle joint. This contributes to the longevity of the TAR prosthesis. It is unclear whether pre-operative templating is more accurately performed using an AP radiograph or 3-Dimensional (3D) imaging using MRI or CT. We sought to compare the accuracy of pre-operative templating with an AP radiograph versus CT/MRI, in relation to the size of the implanted prosthesis.Methods:29 patients undergoing TAR with BOX™ TAR between July 2014 and September 2015 were included in the study. Data was collected prospectively using a TAR database. Pre-operative templating of Tibial and Talar width using AP Radiographs was performed and recorded onto the database (Fig1). The implant sizes used was also ...
