目的 比较数字优化设计导航模板虚拟模型和3D打印模型之间的差异。 方法 收集2018年1月至2022年10月就诊西南医科大学附属中医医院的80名肩锁关节脱位患者的肩关节CT图像（37名女性和43名男性患者），将其CT图像导入Mimics软件，建立虚拟与真实导航骨隧道，设计并打印80个包括锁骨和肩胛骨在内的肩关节，分别测量虚拟与真实导航骨隧道的10个相关参数。 结果 两条骨隧道在9个参数上没有统计学差异（P>0.05），喙突针点到喙突尖的长度（OQ）有统计学差异（P<0.05）。女性患者的所有测量值低于男性（P<0.01）。 结论 数字优化设计导航模板的的虚拟模型具有与3D打印模型相似的准确性，可用于临床肩锁关节脱位需喙锁韧带重建术治疗的患者进行骨隧道定位。

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.
