Bone Surface Registration Patent for Orthopedic Procedures
Summary
USPTO published patent application US20260108306A1 (Application No. 19423871) on April 23, 2026, disclosing systems and methods for negative registration of bone surfaces used in orthopedic procedures. The invention enables a computing device to project geometry data of a first bone-contacting surface into a second bone's coordinate space and map the projected geometry across multiple poses within a patient's range of motion to generate data indicative of the second bone-contacting surface. The patent lists Adam Ryals and Daniel Girardeau-Montaut as inventors.
“The computing device also maps the projected geometry to a plurality of poses in a range of motion of the first bone relative to the second bone using position data indicative of relative positions of the first bone and the second bone at the plurality of poses in the range of motion.”

What changed
USPTO published application US20260108306A1 disclosing computing-implemented methods for generating bone surface geometry during orthopedic procedures. The system projects first bone-contacting surface data to a second bone's coordinate space and maps the projected geometry across a range of motion poses to identify intersecting geometry representing the second bone-contacting surface. The filing covers systems and methods applicable to surgical planning and navigation for joint procedures.
Manufacturers and developers of orthopedic surgical navigation systems, robotic surgery platforms, and preoperative planning software should treat this published application as prior art. While the patent is not yet granted, competitors in the bone registration and computer-assisted orthopedic surgery space should review their own technology portfolios for potential overlap and consider the implications of this disclosure for Freedom to Operate analyses.

Abstract
Systems and methods for bone surface geometry generation include a computing device. The computing device projects first geometry data indicative of a first bone-contacting surface of a first bone of a patient to a coordinate space of a second bone of the patient to generate projected geometry. The second bone includes a second bone-contacting surface that interfaces with the first bone-contacting surface. The computing device also maps the projected geometry to a plurality of poses in a range of motion of the first bone relative to the second bone using position data indicative of relative positions of the first bone and the second bone at the plurality of poses in the range of motion. The computing device further selects intersecting geometry from the mapped, projected geometry to generate second geometry data indicative of the second bone-contacting surface.
