Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
