Abstract
The present disclosure provides methods of identifying a loosened joint implant by analyzing acoustic emissions from the implant. The present disclosure further provides apparatuses for measuring acoustic data and analyzing acoustic emissions from a joint implant.
Claims19
A method of identifying a loosened implant in a joint, the method comprising the steps of:
- positioning a plurality of acoustic sensors at a respective plurality of locations around the joint,
- causing the joint to be moved,
- receiving signals from the acoustic sensors during the movement of the joint,
- identifying signals from two or more of the plurality of acoustic sensors that correspond to a common acoustic event,
- identifying a position of the acoustic event within the joint, and
- providing a health indication related to the joint.
3 more elements
A method of identifying a loosened implant in a joint, the method comprising the steps of:
- positioning an acoustic sensor at a location proximate to the joint,
- causing the joint to be moved,
- receiving a signal from the acoustic sensor during the movement of the joint,
- analyzing the signal to identify an attribute that is associated with a state of joint health, and
- providing a health indication related to the joint.
2 more elements
An apparatus for identifying a loosened implant in a joint, the apparatus comprising the steps of:
- a plurality of acoustic sensors configured to be placed in contact with a patient's skin at a respective plurality of locations around the joint,
- a processor configured to receive signals from the acoustic sensors during the movement of the joint, wherein the processor is configured to:
- identify signals from two or more of the plurality of acoustic sensors that correspond to a common acoustic event,
- compare an attribute of the signals,
- identify a position of the acoustic event within the joint, and
- provide a health indication related to the joint.
