手舟骨血供3D可视化模型的制备
The establishment of visual model of the scaphoid bone and its nutrient artery
目的 建立手舟骨动脉血供三维数字可视化模型，为基础研究及临床应用提供形态学基础。 方法 8具尸体行一次性全身动脉造影、螺旋CT扫描，运用Mimics软件构建腕骨及手舟骨滋养动脉的3D可视化模型。 结果 （1）该模型能够清晰显示桡骨、尺骨远端与手部各骨及其周围血管网，并可任意旋转观察与测量；（2）手舟骨有3支主要的滋养动脉；（3）通过选择性透明或隐藏处理后，对手舟骨营养血管入骨点及其在骨内的分布情况得到了很好的显示。 结论 该模型可清晰的显示手舟骨及其滋养动脉的来源、分布、及空间毗邻，可为手舟骨疾患的临床诊治提供直观的数字化解剖学依据。
Objective To study the blood supply of the scaphoid bone by the three-dimensional visualization model，and to provide technical platform for basic research and clinical application. Methods Eight fresh cadavers were injected for three-dimensional reconstruction of the carpal and scaphoid's nutrient arteries using a spiral computed tomography scanner and three-dimensional reconstruction by MIMICS. Results (1)The radial bone，ulnar bone, proximal wrist bone, and the radial artery were reconstructed.(2)There were 3 major nutrient arteries in the scaphoid bone.(3)The model could display the location, origin, distribution, and adjacent structures of the scaphoid bone and its blood distribution. The reconstructed structures could be continuously rotated in 3D space at different velocities. Conclusions The model can clearly display the scaphoid bone and sources of its nutrient arteries, distribution, and provide visual digital anatomical information for clinical diagnosis and treatment of scaphoid bone diseases.
