Abstract: Objective    To compare the differences between the virtual model of the digital optimization design navigation template and the real model of 3D printing.    Methods    Shoulder CT images were collected from 80 patients (37 women and 43 men) from January 2018 to October 2022. The patient’s CT images were imported into Mimics software to create virtual and real navigation bone tunnels. The 10 parameters were measured for virtual and real navigator bone tunnels.    Results    We designed and printed 80 shoulder joints including collarbones and shoulder blades. There was no statistically significant difference in 9 parameters (P>0.05) between the two bone tunnels, but there was a statistically significant difference in OQ (the length of the coracoid needlepoint to the coracoid tine)(P<0.05). All measurements were lower in female patients than in male patients (P<0.01).   Conclusions   The virtual model of digital optimization design has similar accuracy to the real model of 3D printing. In clinical practice, patients with acromioclavicular dislocation requiring coracoclavicular ligament reconstruction can try to locate bone tunnels using a virtual model of the digitally optimized design navigation template.
