摘　　要：目的:建立3D金属打印技术IdebergⅡ型区域肩胛盂骨折解剖钢板的数字化模型。方法:回顾性选择1例34岁健康男性志愿者的肩胛骨影像学资料,运用Mimics 15.01,NX 12.0等软件设计IdebergⅡ型区域肩胛盂骨折导向钢板系统,将STL数据输入金属3D打印机打印1∶1肩胛骨模型及带导向套筒的肩胛盂解剖钢板,并在体外试验钢板的贴合性和影像学评估螺钉位置的准确性,记录肩胛骨模型的打印时间、钉道设计及解剖导向钢板制作时间。结果:3D金属打印的IdebergⅡ型肩胛盂骨折导向钢板与3D打印肩胛骨模型贴合良好,锁定螺钉导向准确,X线及CT扫描显示螺钉位置良好。肩胛骨模型打印时间、钉道设计及异形解剖导向钢板制作的时间分别为52.0、15.0、320 min。结论:基于3D金属打印技术的解剖钢板可实现IdebergⅡ型区域骨折良好贴合和螺钉的精确置入,为IdebergⅡ型肩胛盂骨折的治疗方案提供一种新的精确手术方法。Objective To establish digital model of Ideberg typeⅡregional glenoid fracture anatomical plate with 3D metal printing technology.Methods The scapular imaging data of a 34-year-old healthy male volunteer were retrospectively selected.Mimics 15.01,NX 12.0 and other software were used to design Ideberg typeⅡregional scapular fracture guide plate system.STL data were input into a metal 3D printer to print 1∶1 scapular model and anatomical plate of scapular pelvis with guide sleeve.The fit of the plate was tested in vitro and the accuracy of the screw position was evaluated by imaging.The printing time of scapular model,design of the nail path and making time of the anatomic guided plate were recorded.Results 3D metal-printed Ideberg typeⅡguide plate for scapular fracture fitted well to 3D printed scapular model,the locking screw was oriented accurately,and X-ray and CT showed good screw position.The printing time of scapula model,time of nail path design and special-shaped anatomical guide plate production were 52.0,15.0 and 320 min,respectively.Conclusion Anatomical plates based on 3D metal printing technology could achieve good adhesion of Ideberg typeⅡregional fractures and precise screw placement,providing a new and accurate surgical method for the treatment of Ideberg typeⅡglenoid fractures.
