Publication number: 20200315634Abstract: A method of creating a patient specific instrument (PSI) for use in knee replacement surgery is described which includes using a digital bone model generated using at least two two-dimensional X-ray scans of a bone, each of the X-ray scans being taken from different angular positions. Locations for one or more anchor points on the PSI which are adapted to abut a surface of the bone are determined, the determined locations of the anchor points being disposed on the PSI at locations corresponding to areas of expected high accuracy on the digital bone model generated by the X-ray scans. The areas of expected high accuracy include at least a peripheral bone contour in at least one of the angular position of the X-ray scans. A method of positioning a surgical guide using such a PSI is also disclosed.Type: ApplicationFiled: June 23, 2020Publication date: October 8, 2020Inventors: Pierre COUTURE, Trong Tin NGUYEN, Anselm NEUROHR, Jean-Sébastien MERETTE
