A novel modularized splint was designed to have functions of fixation, traction and flexibility following the principle of modern osteosynthesis, to overcome the shortage of the common non-surgical treatment of distal radius fracture. A concrete design with detailed kinematic and mechanical analysis was put forward. Then experiments which built relationships between displacement with skin deformation and moment of wrist rotation with angle were set. The results indicated that the novel splint was able to realize traction by displacement, and had sufficient stiffness in fixation mode, while had a changeable range of motion and stiffness in flexible mode. Therefore, the effectiveness of the mechanism could be proved and the foundation of further research was laid.
