Dynamic traction for unstable fractures of the distal radius

We have designed a flexible distracter through which dynamic traction is applied to fractures of the distal radius. The distraction is maintained during flexion and extension as well as radial and ulnar deviation. The results in 30 patients showed that the majority of the fractures maintained reduction during the period of dynamic traction. In several patients the radiological variables even improved during dynamic traction. The median radial shortening was 0 mm, the palmar angulation 7 degrees, and the radial inclination 23 degrees. Continuous dynamic traction applied to fractures of the distal radius did not lead to redisplacement of the fracture, and the overall functional results were good.
