Orthpaedic monitoring system, methods and apparatus

摘要

A method for assessing the orthopedic performance of a joint of a patient can comprise implanting at least a first and second RF wirelessly detectable markers in first and second bones associated with a site and determining and storing their positions before a surgical procedure is performed. The procedure can be carried out on the site and the positions of the first and second markers can be detected and stored after the procedure has been completed. The detected positions can be used to generate a representation of the orthopedic performance of the joint after the procedure.

1. A method for assessing the orthopaedic performance of a patient after a surgical procedure has been carried out on a joint of the patient, the patient having a first marker attached to a first bone associated with a joint and a second marker attached to a second bone associated with the joint, the first and second markers being wirelessly trackable at at least one radio frequency, the first and second bone each having bone surfaces, the method comprising:
determining and storing the positions of the first and second markers using a tracking system before the surgical procedure is performed on the joint; determining and storing the positions of the first and second markers using a tracking system after the surgical procedure has been performed on the joint, the surgical procedure comprising cutting at least one of the surfaces of at least one of the first bone and second bone; and generating a representation of the orthopaedic performed of the joint from the stored positions of the first marker and the second marker before the surgical procedure and the positions of the first marker and the second marker after the surgical procedure.
