Orthopaedic fusion planning systems and methods of repair

A system for planning an orthopaedic procedure comprising:

• a computing device including a processor coupled to a memory, and software planning instructions stored in the memory and executable by the processor, the software planning instructions including a display module, a spatial module and a comparison module such that when the software planning instructions are executed by the processor, the processor:
• stores a plurality of bone models including a first bone model and a second bone model in the memory;
• displays the first bone model and the second bone model in a graphical user interface using the display module;
• establishes, using the spatial module, a first resection surface of the first bone model according to a first reference plane;
• establishes, using the spatial module, a second resection surface of the second bone model along a second reference plane;
• positions, using the spatial module, the first resection surface in contact with the second resection surface along a contact region;
• determines, using the comparison module, a contact area ratio defined as a first area of the first resection surface along the contact region divided by a second area of the second resection surface;
• and
• generates, using the comparison module, a first indicator in response to one or more predetermined criteria being met, the one or more predetermined criteria including the contact area ratio meeting a first predefined threshold in the software planning instructions.
