Abstract: A system for intra-operatively registering a pelvis comprising an acetabulum with a computer model of the pelvis in a coordinate system. The system may include: a) a surgical navigation system including a tracking device; and b) at least one computing device in communication with the surgical navigation system. The at least one computing device: i) receiving first data points from first intra-operatively collected points on an articular surface of the acetabulum, the first data points collected with the tracking device; ii) receiving a second data point from a second intra-operatively collected point on the pelvis, the second data point collected with the tracking device, the second data point corresponding in location to a second virtual data point on the computer model; and iii) determining an intra-operative center of rotation of the femur relative to the pelvis from the first data points.

Abstract: A system for surgical registration. The system may include at least one computing device in communication with a surgical navigation system and the surgical device. The at least one computing device: a) receiving external bone registration data corresponding to locations on the exterior surface of the femur; b) calculating a first registration transform based on the external bone registration data; c) transforming a first bone removal plan of a surgical plan to the operative coordinate system based on the first registration transform; d) receiving internal bone canal registration data corresponding to at least one of location or orientation data from the inner canal of the femur; e) calculating a second registration transform based on both of the external and internal bone canal bone registration data; and f) transforming a second bone removal plan of the surgical plan to the operative coordinate system based on the second registration transform.

Abstract: A method of calculating leg length discrepancy of a patient including: receiving patient bone data associated with a lower body of the patient; identifying anatomical landmarks in the patient bone data; orienting a first proximal landmark and a second proximal landmark relative to each other and an origin in a coordinate system; aligning a first axis associated with a first femur and a second axis associated with a second femur with a longitudinal axis extending in a distal-proximal direction, wherein the first and second distal landmarks are adjusted according to the alignment of the first and second axes; calculating a distance between the first and second distal landmarks in the distal-proximal direction along the longitudinal axis; and displaying at least one of the distance or a portion of the patient bone data on a display screen.
