Publication number: 20250204991Abstract: A processor is configured to execute instructions stored in memory to provide guidance during a surgical procedure. Executing the instructions causes the processor to obtain an image of patient anatomy including at least a femur and a pelvis, segment the image into a pelvis portion and a femur portion, generate a pre-operative plan for the surgical procedure using the segmented image, including calculating, using the segmented image, a surgical area of interest between the pelvis portion and the femur portion and a minimum distance between the femur and the pelvis within the surgical area of interest, and generate and provide, via a display, visual guidance for performing distraction during the surgical procedure, the visual guidance being generated based on the minimum distance.Type: ApplicationFiled: December 16, 2024Publication date: June 26, 2025Applicants: Smith & Nephew, Inc., Smith & Nephew Orthopaedics AG, Smith & Nephew Asia Pacific Pte.
