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.

40. An orthopedic system for orienting a cutting plane during a joint replacement procedure comprising:
-
a base member attachable to a bone; at least one adjustment device coupled to and moveable relative to the base member in at least one degree of freedom; a portable surgical orientation device coupled or configured to couple to the at least one adjustment device, the portable surgical orientation device comprising; a housing, an inertial sensor configured to monitor the orientation of the portable surgical orientation device in a three-dimensional coordinate reference system upon moving and/or swinging an extremity of the patient or the portable surgical orientation device, and an electronic control unit configured to determine a center of rotation of a joint and/or a mechanical axis based upon data produced by the inertial sensor. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)

53. A method of performing an orthopedic procedure, comprising:
-
coupling a base member to a bone; coupling a portable surgical orientation device to at least one adjustment device coupled to the base, the portable surgical orientation device comprising an inertial sensor; moving and/or swinging an extremity of the patient or the portable surgical orientation device, wherein the inertial sensor monitors the orientation of the portable surgical orientation device in a three-dimensional coordinate reference system upon moving and/or swinging the extremity of the patient or the portable surgical orientation device; and wherein the system determines a center of rotation of a joint and/or a mechanical axis of a bone based on data produced by the inertial sensor. - View Dependent Claims (54, 55, 56, 57, 58, 59)
