1. A method of pre-operatively developing a shoulder arthroplasty plan, the method comprising:
receiving an image of a patient shoulder comprising a humerus and a glenoid;
performing virtual surgery on a three-dimensional (3D) shoulder model, based at least in part on the image, using a system to generate a modified shoulder model including implanting within the 3D shoulder model a virtual representation of a humeral implant on a virtual humerus and a virtual representation of a glenoid implant on a virtual glenoid;
determining, using the system, a range of motion of the patient shoulder based on finite element analysis of the modified shoulder model including determining an expected interaction between the virtual representation of the humerus implant and the virtual representation of the glenoid implant; and
selecting, using the system and in response to determining that the range of motion is not within a desired range, at least one of a second humeral implant and a second glenoid implant.
