Additional use of a novel patient-specific glenoid vault model can predict premorbid version, inclination, and amount of volumetric bone loss. Surgical simulation in a 3-dimensional virtual environment using commercially available implant templates provides both position and sizing estimation to generate the best possible scenario of bony structural support for the glenoid implant and can minimize the amount of bone loss by reaming. Preoperative planning with these techniques can enhance decision-making and surgical execution providing the surgeon with the most information possible to recreate a patient’s anatomic shoulder relationships. © 2012 Lippincott Williams & Wilkins, Inc.
