Poor reduction can lead to complications such as deformity and delayed fracture healing. We introduce a 3D printed external fixator technology that can assist in fracture reduction and fixation.
A fractured long bone was first fixed by a temporary external fixator and then scanned with computed tomography. Three-dimensional reconstruction of the contour and bone fragments of the affected limb was performed using Mimics software, and the fracture reduction was simulated. Subsequently, data were imported into SolidWorks software for customized external fixator design and 3D printing. Through the precise assembly of the 3D printed external fixator and external fixation pins, automatic fracture reduction.
The patient's fractures were well reduced, firmly fixed, and the postoperative fractures healed well with no complications.
The technique we introduce not only assists in fracture reduction for temporary external fixation but can also be used as a definitive treatment for long bone fractures.
复位不佳可导致畸形和骨折愈合延迟等并发症。我们介绍一种 3D 打印外固定架技术,可辅助骨折复位和固定。
先使用临时外固定架固定骨折的长骨,然后进行计算机断层扫描。使用 Mimics 软件对受影响肢体的轮廓和骨碎片进行三维重建,并进行骨折复位模拟。随后,将数据导入 SolidWorks 软件,进行定制外固定架设计和 3D 打印。通过 3D 打印外固定架和外固定针的精确组装,实现自动骨折复位。
患者骨折复位良好,固定牢固,术后骨折愈合良好,无并发症。
我们介绍的技术不仅可辅助临时外固定的骨折复位,还可作为长骨骨折的确定性治疗方法。
