title: [New concepts of monitoring and assessment of bone union stiffness in fractures treated by Dynastab DK external fixation].
abstract: This paper focuses on heuristic techniques based on artificial intelligence namely artificial non-linear and multilayer neurons employed for assessment of bone union in fractures treated by Dynastab DK external fixation. The software used allowed for prediction of bone union curve at the early stage of treatment. The training of the neural net has been done on the ground of 56 cases of Dynastab DK treated fractures. The net served for periodical assessment of bone union and its further prediction in 17 long bone shaft fractures. Bone mechanical properties at the fracture site showed non-linear changes in time. Specifically great changes were noted 4 months postoperatively. Flexion at the fracture site is critical. Neuron net proved to be useful in predicting bone union curve.
