1. A method for surgical planning, comprising: displaying a set of related two-dimensional (2D) anatomical images; identifying a plurality of anatomical landmarks on the set of 2D anatomical images; creating a 3D anatomical model from the set of related 2D anatomical images using at least one of the plurality of anatomical landmarks, wherein the 3D anatomical model comprises the plurality of anatomical landmarks located in three dimensions; scaling a three-dimensional (3D) representation of a parent prosthesis to match a scale of the set of related 2D anatomical images based at least in part on a relationship between the plurality of anatomical landmarks; relating the plurality of anatomical landmarks located in three dimensions to the 3D parent prosthesis; and displaying a 2D representation of the scaled 3D parent prosthesis on at least one of the set of related 2D anatomical images.
