The 3D printing technology is a relatively new procedure with a high potential, especially in the field of shoulder surgery. The 3D printing procedures are increasingly being developed and also gaining new users. Principally, 3D printing procedures can be applied preoperatively in planning the surgical procedure, patient clarification and in teaching; however, the technology is increasing being used intraoperatively. In addition to intraoperative visualization of the models, 3D printing permits the use of individual and specific instruments and implants. This allows the precise transfer of the preoperative planning to the surgical procedure. Inaccuracies are mainly caused by soft tissues. The 3D printing can be beneficial in the fields of arthroplasty, shoulder instability as well as orthopedic trauma. The literature shows promising results in relation to duration of surgery, blood loss and clinical results of the procedure. On the other hand, it is still unclear which indications warrant the use of 3D printing. Other aspects that raise questions are the time of planning, the production time and the additional cost that the use of 3D printing entails. Nonetheless, 3D printing represents a meaningful enhancement of the portfolio of surgeons, which becomes highly beneficial and useful in complex situations. Furthermore, this procedure enables a certain amount of flexibility when reacting to certain circumstances.
3D打印技术是一种潜力巨大的相对较新的手术方法，尤其在肩部手术领域。3D打印手术方法正在不断发展，并且有越来越多的新用户。原则上，3D打印手术方法可在术前用于手术规划、患者说明和教学；然而，该技术在术中的应用也越来越多。除了术中对模型的可视化，3D打印还允许使用个性化和特定的器械及植入物。这使得术前规划能够精确地应用于手术过程。不准确主要是由软组织引起的。3D打印在关节成形术、肩部不稳定以及骨科创伤领域可能会有帮助。文献显示，在手术时长、失血量和手术临床效果方面有令人期待的结果。另一方面，仍不清楚哪些适应症适合使用3D打印。其他引发问题的方面包括规划时间、制作时间以及使用3D打印所带来的额外成本。尽管如此，3D打印是外科医生技术组合中有意义的补充，在复杂情况下非常有益且实用。此外，该手术方法在应对某些情况时具有一定的灵活性。
