Abstract
Systems and methods are described to determine joint center of rotation during a procedure. Joint center measurements may be useful to determine other clinically relevant measurements and/or to assist with replacement surgery.
Claims20
A system to determine a center of rotation of a joint during a surgical procedure, comprising:
- an electronic guidance system comprising a target to generate relative poses between a first bone and an object, wherein the first bone and the object are connected via the joint having the center of rotation;
- and
- a computing unit comprising circuitry configured to:
- collect an articulation data set comprising poses from the electronic guidance system wherein the poses relate to a target attached to a tool, and wherein the tool is articulated about the center of rotation;
- and
- calculate a joint center of rotation responsive to the articulation data set to guide the surgical procedure.

A method to determine a center of rotation of a joint during a surgical procedure, the method comprising:
- collecting an articulation data set comprising poses from an electronic guidance system comprising a target to generate relative poses between a first bone and an object, wherein:
- the first bone and the object are connected via the joint having the center of rotation;
- and
- the poses of the articulation data set relate to the target attached to a tool as the tool is articulated about the center of rotation;
- and
- calculating a joint center of rotation responsive to the articulation data set to guide the surgical procedure.
3 more elements
A method comprising:
- preparing a joint of a patient for a surgical procedure, the joint connecting a first bone to an object and the joint having a center of rotation;
- coupling to the object a target of an electronic guidance system configured to generate relative poses between the first bone and the object using the target;
- rotating the target about the center of rotation to provide an articulation data set comprising poses from the electronic guidance system to a computing unit configured to calculate a joint center of rotation for the joint responsive to the articulation data set.
