Scaphoid nonunion is a complication that occurs in 5-10% of patients who sustain an acute scaphoid fracture. There is no superior method for managing scaphoid nonunion that has been established in the current literature. The use of patient specific devices has been explored as a way to improve surgical management of scaphoid nonunion. 3D printing has made the production of patient specific devices more accessible. CT and MRI images can be used to model devices such as anatomic models and surgical guides. In this review we aim to discuss the current evidence for the use of patient specific devices for managing chronic scaphoid nonunion and demonstrate their different uses. A scoping review of peer-reviewed literature, existing patent applications, and grey literature was performed. Although the current research has demonstrated some possible benefits such as reduction in surgical time and accuracy of restoration of anatomy, further investigation with comparative studies is required to make conclusions about the superiority of these techniques over standard freehand techniques.
舟骨不愈合是一种并发症，发生于5%至10%的急性舟骨骨折患者中。目前文献中尚未确立治疗舟骨不愈合的最佳方法。探索使用定制器械作为改善舟骨不愈合手术治疗的一种方式。3D打印使定制器械的生产更易实现。CT和MRI图像可用于构建诸如解剖模型和手术导板等器械。在本综述中，我们旨在讨论使用定制器械治疗慢性舟骨不愈合的现有证据，并展示其不同用途。对同行评审文献、现有专利申请和灰色文献进行了范围综述。尽管目前的研究已证明了一些可能的益处，如手术时间缩短和解剖结构恢复的准确性提高，但仍需要通过比较研究进行进一步调查，以得出这些技术优于标准徒手技术的结论。
