1. A method of providing automated measurements associated with anatomical features of a spine, comprising: electronically providing a three dimensional (3-D) model of the spine having substantially naturally shaped vertebrae, with a plurality of landmarks electronically applied to each of the vertebrae; obtaining 3-D patient image data of a spine of the patient; extracting subvolumes of the 3-D patient image data associated with the spine, respective subvolumes each including at least one vertebra in full and at least one neighboring vertebrae structure or a portion thereof; extracting subvolumes of the 3-D model corresponding to the subvolumes of the patient image data; electronically registering, subvolume by subvolume, the 3-D model and the 3-D patient image data of the spine; then electronically transferring the landmarks from the model to the 3-D patient image; and electronically calculating measurements for one or more vertebrae, including at least one of the following: (i) position in x, y and z coordinates (mm), (ii) rotation θx, θy, θz in degrees, and (iii) a local deformity (lateral wedge) value (mm) using the transferred landmarks.
