In Vitro Comparative Study Between Conventional and Computer-Assisted Surgery Methods for Planning and Resection of Bone Sarcomas

摘要

This poster aims to achieve an "in vitro" comparative study between three methods: 2D digital images planning and execution without navigation (freehand with ruler and caliper), 3D planning and execution without navigation (freehand with ruler and caliper) and 3D planning and execution guided with navigation. 3D planning and navigated procedures potentially improve sarcoma resection. Surgeons plan surgeries using bi-dimensional images from magnetic resonance and tomography to define the rumor extension and then handle standard tools intraoperatively (caliper and ruler) to resect bone sarcoma. We wonder if surgeons have more information about the spatial tumor situation before and during the surgical procedure would it reduce the risk of potential sarcoma recurrence? Thus, the aim of this comparative study is to reach ideal "in vitro" conditions with an experimental design to answer these questions: Which type of planning method is safest for planning an oncologic margin? Which type of executing method is safest for sarcoma resection?
