Abstract:
BACKGROUND: Minimally invasive percutaneous plate osteosynthesis for humeral shaft fractures (HSFs) has limitations due to malreduction and radiation exposure. To address these limitations, we integrated robotics and 3D printing by incorporating plates as reduction templates.
METHODS: The innovative technology facilitated closed reduction of HSFs in the operating theatre using 18 models with cortical marking holes. The dataset of the precontoured plate was imported into 3D planning software for virtual fixation and screw path planning. The models were divided into half to simulate transverse fractures. During the operation, the software generated drilling trajectories for robot navigation, and precise plate installation achieved automatic fracture reduction.
RESULTS: The evaluation results of reduction accuracy revealed variations in length, apposition, alignment, and rotation that meet the criteria for anatomic reduction. High interoperator reliabilities were observed for all parameters.
CONCLUSIONS: The proposed technology achieved anatomic reduction in simulated bones.
摘要:
背景:微创经皮钢板内固定治疗肱骨干骨折(HSF)由于复位不良和辐射暴露而存在局限性。为了解决这些限制,我们集成了机器人和3D打印结合板作为减少模板。
方法:创新技术使用18种带有皮质标记孔的模型,促进了手术室中HSF的封闭式减少。将预成型板的数据集导入三维规划软件进行虚拟固定和螺钉路径规划。将模型分成两半以模拟横向骨折。在操作过程中,软件生成的机器人导航钻孔轨迹,和精确的钢板安装实现了自动骨折复位。
结果:降低精度的评估结果显示长度变化,并置,对齐,和符合解剖复位标准的旋转。对于所有参数都观察到高操作员间可靠性。
结论:所提出的技术实现了模拟骨骼的解剖还原。
