Angular Displacement Sensor for Joints And Associated System and Methods
First Claim
1. A system for monitoring joint position following introduction of a joint prosthesis in a patient, the system comprising:
- a first angular movement sensor positionable adjacent a first side of a bodily joint of a patient;
a second angular movement sensor positionable adjacent a second side of the bodily joint of the patient, the second side on an opposite side of the bodily joint from the first side;
a receiver adapted to receive data from the first and the second angular movement sensors;
a processor in signal communication with the receiver having comparison means resident thereon for determining whether the received data from the first and the second angular movement sensors indicate that movement of the bodily joint is less than a predetermined limit; and
an indicator in signal communication with the comparison means forwarning the patient if the joint movement is determined by the comparison means to be above the predetermined limit.

Abstract
A system for monitoring joint position following introduction of a joint prosthesis in a patient includes a first angular movement sensor positioned adjacent a first side of a bodily joint of a patient and a second angular movement sensor positioned adjacent a second, opposite side of the bodily joint. A receiver can receive data from the angular movement sensors. A processor in signal communication with the receiver has a comparator for determining whether the received data from the sensors indicate that movement of the bodily joint is less than a predetermined limit. An indicator in signal communication with the comparator is provided for warning the patient if the joint movement is determined by the comparator to be above the predetermined limit. The received data can be tracked over time.

18. A method for monitoring joint position following introduction of a joint prosthesis in a patient, the method comprising:
-
sensing a first angular movement using a first sensor positioned adjacent a first side of a bodily joint of a patient; sensing a second angular movement using a second sensor positioned adjacent a second side of the bodily joint of the patient, the second side on an opposite side of the bodily joint from the first side; receiving data from the first and the second sensors; determining whether the received data indicate that movement of the bodily joint is less than a predetermined limit; and warning the patient if the joint movement is determined to be above the predetermined limit. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
