Do 3D Printed Calcaneus Models Change Fracture Classification and Surgical Planning?:

摘要

Category:HindfootIntroduction/Purpose:Roy Sanders clearly described the classification and management of calcaneus fractures over two decades ago. Despite this clear explanation, later authors have questioned inter-observer reliability of the sanders classification scheme. In part, this may be due to the complex geometry of the calcaneus and its known fracture patterns. Recently, 3D printed models have been used to better understand complex distal radius fractures. We hypothesize that patient-specific 3D printed models of calcaneus fractures should give surgeons a better understanding of the fracture pattern which would result in more reliable fracture classification and treatment plans between different surgeons. The purpose of this work is to evaluate the superiority of 3D printed models vs standard CT scans with respect to reliability of fracture classification and surgical plan.Methods:Following IRB approval, the surgical billing database at a level one trauma center was queried for calcaneus fracture...
