1. A pre-operative planning method for designing a shoulder surgery guide, the method comprising:
receiving, with a computing system, one or more images of a shoulder of a subject;
virtually aligning, with the computing system, at least one implant to a virtual representation of a glenoid of the shoulder;
conducting, with the computing system, a range of motion analysis of the virtual alignment of the at least one implant to the virtual representation of the glenoid, the range of motion analysis including virtually positioning the virtual alignment of the at least one implant to the virtual representation of the glenoid through ranges of motion of the shoulder to measure impact locations and to compensate for necessary functional range of motion of the shoulder;
comparing, with the computing system, vectors in three dimensions, wherein the vectors comprise a distance and direction, measured in the one or more images, between tendon and muscle insertions on a scapula and a humerus of the subject of the shoulder of the subject, wherein the vectors measure the distance of relocation of humeral tuberosity compared to the scapula of the shoulder of the subject;
generating, with the computing system, information, for the pre-operative planning, indicative of at least one of a selection of glenoid implant, humeral implant, or information for creation of the shoulder surgery guide based on the range of motion analysis and the comparison of the vectors; and
outputting, with the computing system, the generated information for the selection of the glenoid implant, the humeral implant, or the creation of the shoulder surgery guide.
