Digital Sizing for Orthopaedic Hip Implants

Ottawa Hospital Research Institute100 enrolled

Overview

Hip implants come in different sizes. Currently, surgeons predict the implant size that will be needed using an analogue method whereby photos of the implant sizes are overlaid on the x-rays. In this study, we propose to use a digital, computerized method of templating which we expect will be more accurate than the overlay method.
