摘　　要：目的收集CT扫描尺骨冠状突数据,利用3D打印技术结合计算机模型设计软件设计尺骨冠状突解剖钢板。方法收集2017年9月至2022年1月于昆明医科大学第一附属医院创伤中心行肘关节(肘关节无明显解剖变异且无骨折、无肘关节手术史)的102例志愿者CT扫描数据进行回顾性分析。男52例,女50例。运用RadiAnt DICOM Viewer软件以及Mimics Medical 21.0软件将肘关节CT数据图像化表达后并运用软件测量尺骨冠状突尖与尺骨粗隆夹角、尺骨冠状突1/2高度处宽度、尺骨冠状突尖至尺骨粗隆水平面距离、螺钉置入安全角度。然后使用Siemens Ungraphics NX12.0软件结合测量值设计尺骨冠状突解剖钢板及螺钉导向装置,将设计出的钢板模型运用3D打印技术制作出1∶1的尺骨冠状突钢板模型,并将钢板模型置于成人尺骨冠状突模型,对该钢板模型匹配度进行验证,与成人尸体骨尺骨冠状突进行匹配实验,并在体外模拟该钢板模型模拟手术的可操作性。结果男性、女性左侧与右侧尺骨冠状突与尺骨粗隆夹角、尺骨冠状突1/2高度处宽度、尺骨冠状突尖至尺骨粗隆水平面距离、螺钉置入安全角度的比较差异均无统计学意义(P>0.05)。男性与女性尺骨冠状突尖与尺骨粗隆夹角、螺钉置入安全角度的比较差异均无统计学意义(P>0.05)。男性与女性尺骨冠状突1/2高度处宽度、尺骨冠状突尖至尺骨粗隆水平面距离比较差异均有统计学意义(P<0.05)。但经过计算机模拟适配以及钢板模型模拟适配实验,发现按男、女各项参数设计的尺骨冠状突解剖钢板可以通用,2种模型贴合度均好、各螺钉置入角度安全。结论本研究设计的尺骨冠状突解剖钢板模型贴合度可,螺钉置入角度安全,基本达到了预期设计目标,为下一步钛合金钢板制作提供了依据。尺骨冠状突解剖钢板不需要设计专用于男、女并区分左、右的钢板,仅需�Objective To design an anatomical plate of ulna coronoid process using 3D printing and computer model design software based on a collection of CT scanning data of the ulna coronoid process.Methods The CT scans of the elbow joint with no obvious anatomic variation,no fracture,or no history of elbow operation were collected which had been taken at Trauma Center,The First Affiliated Hospital of Kunming Medical University from September 2017 to January 2022.There were 52 males and 50 females.RadiAnt DICOM Viewer and Mimics Medical 21.0 were used to visualize the CT data of the elbow joint of 102 volunteers.The software was used to measure the angle between the tip of the ulna coronoid process and the tuberosity of the ulna,the width at 1/2 height of the ulna coronoid process,the distance between the tip of the ulna coronoid process and the horizontal plane of the ulna tuberosity,and the safety angle for screw placement.After the values were measured,Siemens Ungraphics NX12.0 software was used to design the anatomical plate and the screw guide device of the ulna coronoid process.After the plate model was designed,a 1:1 actual plate model of the ulna coronoid process was produced by 3D printing.The actual plate model was placed onto an adult model of the ulna coronoid process and an adult cadaveric specimen of the ulna coronoid process to verify its matching degree.An in vitro operation was simulated using the plate model to verify its operability.Results There were no significant differences between the left and right sides in the angle between the tip of the ulna coronoid process and the tuberosity of the ulna,the width at 1/2 height of the ulna coronoid process,the distance between the tip of the ulna coronoid process and the horizontal plane of the ulna tuberosity,or the safety angle for screw placement in either males or females(P>0.05).There were no significant differences between males and females in the angle between the tip of the ulna coronoid process and the tuberosity of the ulna or in the safety angle for
