Digital Sizing for Orthopaedic Hip Implants

October 24, 2011 updated by: Ottawa Hospital Research Institute

Photo-manipulation of Digital Radiographs and Digitized Templates as a Method for Preoperative Sizing of Total Hip Arthroplasties

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.
