Abstract
A method for diagnosing a joint condition includes in one embodiment: creating a 3d model of the patient specific bone; registering the patient's bone with the bone model; tracking the motion of the patient specific bone through a range of motion; selecting a database including empirical mathematical descriptions of the motion of a plurality actual bones through ranges of motion; and comparing the motion of the patient specific bone to the database.
Claims20
A method of analyzing motion of a patient's bones, the method comprising:
- registering each of a plurality of patient bones with a corresponding virtual 3D bone model;
- non-invasively tracking the motion of the plurality of patient bones through a range of joint motion;
- selecting a database comprising empirical mathematical descriptions of motion of a plurality of actual bones through a comparable range of joint motion;
- and
- comparing the motion of the plurality of patient bones to the database.
A method of monitoring an enclosed joint, the method comprising:
- non-invasively placing an inertial sensor approximate the enclosed joint;
- gathering vibration data using the inertial sensor while moving the enclosed joint through a range of motion;
- and
- simultaneously with gathering the vibration data, gathering kinematics data pertaining to the enclosed joint.
A method of diagnosing an enclosed joint condition, the method comprising:
- creating a virtual 3D model of components of the enclosed joint;
- obtaining vibration data and kinematics data while moving the enclosed joint through a range of motion;
- correlating the kinematics data with the virtual 3D model of components of the enclosed joint to generate a virtual 3D dynamic model of components of the enclosed joint;
- and
- analyzing the vibration data and the virtual 3D dynamic model to diagnose at least one of the presence and severity of a joint degradation.
