Abstract
Systems and methods for joint replacement are provided. The systems and methods include a surgical orientation device and at least one orthopedic fixture. The surgical orientation device and orthopedic fixtures can be used to locate the orientation of an axis in the body, to adjust an orientation of a cutting plane or planes along a bony surface, to distract a joint, or to otherwise assist in an orthopedic procedure or procedures.
Claims20
A method of performing an orthopedic procedure, comprising:
- coupling an orthopedic fixture and a portable surgical orientation device with a distal portion of a limb that comprises a portion of a ball-and-socket joint, the portable surgical orientation device including a housing enclosing an inertial sensor and a microprocessor;
- activating the inertial sensor within the portable surgical orientation device, such that the inertial sensor output is indicative of orientation, velocity, and/or position;
- collecting the inertial sensor output from the inertial sensor using the portable surgical orientation device;
- determining with the portable surgical orientation device a center of rotation of a ball portion of the limb based on the inertial sensor output;
- and
- determining with the portable surgical orientation device a location of the mechanical axis of the limb based on the inertial sensor output.
