Design and Application of Computer-assisted Distal Radial Anatomic Splint / 世界科学技术-中医药现代化

ABSTRACT

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 squeez-ing 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 re-quirements. 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.
