1. A method for planning/guiding alterations to a bone comprising:
obtaining, using one or more processors of a computer-assisted surgery system, orientation-based data for at least two degrees of freedom in orientation from a positioning block secured to the bone, the positioning block having an inertial sensor unit moving concurrently therewith, an orientation of the positioning block being adjustable with respect to the bone by movement;
determining, using the one or more processors of the computer-assisted surgery system, an orientation reference of the bone from the orientation-based data of the positioning block; and
calculating and outputting, using the one or more processors of the computer-assisted surgery system, bone alteration parameters from the orientation-based data of the positioning block with respect to the orientation reference of the bone
wherein the outputting of the bone alteration parameters is displayed in real-time in a same field of view of an operator as the positioning block.
