目的：利用计算机3D-MAX软件辅助设计桡骨远端解剖型支架夹板，制作更符合人体解剖及治疗特点的支架夹板。方法：根据人机工程学设计原理，选取志愿者模特前臂及腕部制作石膏夹板，测量数据，经计算机3D-MAX 软件处理，设计桡骨远端解剖型支架夹板的三维立体模型，并将数据转化为图纸，制作桡骨远端解剖型支架夹板。结果：桡骨远端解剖型支架夹板较纸质支架夹板更符合人体解剖特点，临床使用不需塑形，不影响夹板原有的生物力学性能，不会出现挤压不适等主诉。结论：利用3D-MAX软件辅助设计制作桡骨远端解剖型纸质支架夹板三维模型，提供了桡骨远端夹板各关键部位的重要参数，设计出的夹板更符合人体解剖形态及临床治疗需求，避免了进一步塑形而造成的夹板生物力学性能的丧失，临床使用更方便，疗效更确切，临床推广使用前景广阔。

This study was aimed to design the distal radial anatomic splint which was more in line with the human anatomy and treatment characteristics using the computer design software 3D-MAX. According to ergonomic design principles, the forearm and wrist plaster splint were selected from volunteer models. Then, data of the plaster was measured and input into the computer for the design of the three-dimensional model of distal radial anatomic splint with 3D-MAX software. Finally, the blueprint was drawn for the factory to make the distal radial anatomic splint. The results showed that the distal radial anatomic splint was more in line with human anatomy, which did not require shaping in clinical using. It did not affect the biomechanical properties. And the patients never complain the squeezing discomfort of the splint. It was concluded that the three-dimensional model of the distal radial anatomic splint, which designed with 3D-MAX software, provided key parameters of the important part of the distal radial anatomic splint. Therefore, the produced splint was more in accordance with the human anatomy and the clinic treatment requirements. It avoided the loss of biomechanical properties after shaping, which was more convenient and effective in the clinical using. Its clinical promotion has a broad prospect.
