Application of digital photography in biomechanical studies of osteosynthesis systems

Proposed and experimentally grounded non-contact method for measuring the displacement of bone fragments with the help of digital photography. The described technique is both a direct measurement of displacements along the marks established at the points under study in the fracture zone, and by the analytical method with the positions of the reference points outside the fracture zone. The results of measurements of displacements by the proposed method and the traditional method using a cathetometer. A comparison of the results obtained confirmed the suitability of the method for measuring the displacement of bone fragments with the help of digital photography for practical use.
