    Abstract: A system and method perform a registration such as for a surgical navigation system by fitting a plurality of anatomical points as received to a digital model and developing a map having a corresponding confidence level indicating a degree of certainty. As additional anatomical points are received, they are continually matched to the digital model and the confidence level continually updated. The confidence level is output in any form, such as a score, a color code, or other metric. The output may include a graphical representation e.g. overlaid on an image from the digital model. The output may be a heat map overlaid on the image. The heat map may indicate an overall confidence level, and/or may indicate a plurality of confidence levels at various locations on the digital model. The overlay may provide an indication as to one or more suggested probe points to increase the level.

    Abstract: Provided are methods and systems related to computer-assisted joint replacement surgery, and corresponding instrumentation systems. In one example, there is provided a system for guided surgery comprising: a sensor for coupling to a first bone to receive positional signals; a beacon for coupling to an object to provide the positional signals to the sensor, the object comprising one of a second bone and a surgical tool; a patient-specific jig (PSJ) for guiding a relative position of the sensor and the first bone during coupling to position the sensor in a predetermined pose in an anatomical coordinate frame; and an intra-operative computing unit in communication with the sensor, the intra-operative computing unit configured to calculate poses of the beacon with respect to the anatomical coordinate frame utilizing pre-operative data representing the PSJ and display positional information for the object in real time.
