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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Patient specific instrumentation (PSI) for orthopedic surgery and systems and methods for using X-rays to produce same","description":"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 s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11490902","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
