Experimental study of bone tissue density in patients with congenital pseudarthrosis of the tibia bones before and after surgery according to computer tomography data

Surgical treatment of congenital pseudarthrosis the tibia bones is accompanied by a significant percentage complications and refractions. One main reasons for unsatisfactory results violation quality bone tissue in area pseudoarthrosis, which an obstacle to normal process fusion shin bones. Рurpose - use computed tomography examine density patients with pseudoarthrosis before after surgery. Materials methods. CT scans three tibia, aged 5 7 years. The Hounsfield units cortical layer above below nonunion zone was determined. Results. Prior treatment, decrease (p=0.001) injured limb along its entire length year surgery, statistically difference remains. optical damaged significantly less than healthy (p=0.001). surgical osteosynthesis intramedullary rod axial mobility, operated limbs remains limb. On unoperated limb, (p<0.05) increase observed all studied areas. Conclusions. As result there layer. surgery close due not only growth patients, but also occurs possibility loading research carried out accordance principles Helsinki Declaration. study protocol approved Local Ethics Committee participating institution. informed consent patient obtained conducting studies.
