Changes in regenerated bone optical density at the stages of surgical treatment of forearm bone defects and pseudoarthroses

97 x-ray images of 19 patients with posttraumatic defects of forearm bones have been analyzed using "DiaMorph" computer-assisted complex. Mean optical density of regenerated bone shadows has been evaluated for the purpose of studying the dynamics of osteogenesis and mineralization of newly formed bone tissue during osteosynthesis. By planimetry of distraction regenerated bones it was established that osteogenesis developed by normoplastic type. Typical distraction regenerated bones were formed while filling defect-diastases; the regenerated bones lost their zonal structure at the end of fixation period. During formation of wedge-shaped regenerated bones clear zonal structure of newly formed tissue was not traced, the area of interlayer occupied significantly less part than it was in case of filling the defects of forearm bones by fragment lengthening and formation of typical distraction regenerated bone.
