Abstract: A method for estimating an orientation for placement of a prosthetic implant comprises receiving information indicative of a first virtual axis established between estimated positions of two anatomic landmarks in the anatomical area of interest. The method also comprises calculating an orientation of a first virtual plane, the first virtual plane being perpendicular to the first virtual axis. The method further comprises receiving information indicative of a second virtual axis established between at least one of the estimated positions of the first two landmarks and a third anatomic landmark in the anatomical area of interest. The method also comprises calculating an orientation of a second virtual plane based, at least in part, on the first virtual axis and the second virtual axis. The method further comprises estimating an angle between the orientation sensor and at least one of the first virtual plane or the second virtual plane.
