Abstract
Disclosed herein are joint implants and methods for tracking joint implant performance. A shoulder implant according to the present disclosure can include a glenoid implant on a first bone and a humeral implant on a second bone of a shoulder. The glenoid implant can include magnetic markers. The humeral implant can include marker readers to provide positional data of the glenoid implant with respect to the humeral implant. The humeral implant can include at least one sensor to measure kinematic data between the glenoid and humeral implants. A processor can be coupled the marker reader and the at least one sensor. The processor can be configured to output the positional data and the kinematic data to an external source.
Claims21
A shoulder implant comprising:
- a glenoid implant capable of being coupled to a scapula, the glenoid implant including at least one marker, and
- a humeral implant capable of being coupled to a humerus and contacting the glenoid implant, the humeral implant including:
- at least one marker reader to detect a position of the marker to identify positional data of the glenoid implant with respect to the humeral implant,
- at least one sensor to measure kinematic data between the glenoid and humeral implants;
- and
- a processor operatively capable of being communicatively coupled to the marker reader and to the at least one sensor,
- wherein the processor can output the positional data and the kinematic data to an external source.
A method for monitoring a shoulder joint implant performance, the method comprising the steps of:
- coupling a glenoid implant to a first bone of the shoulder joint, the glenoid implant including at least one magnetic marker;
- coupling a humeral implant to a second bone of the shoulder joint, the humeral implant contacting the glenoid implant, the humeral implant including at least one magnetic sensor to detect a magnetic flux density of the magnetic marker and at least one sensor to measure kinematic data between the glenoid and humeral implants;
- tracking magnetic flux density magnitudes and kinematic data over time using the magnetic sensor and the at least one sensor, and
- initiating a warning when any of a tracked magnetic flux density magnitude and kinematic data differ from a predetermined value.
