Radionuclide investigations of reparative osteogenesis in the treatment of spiral fractures of the leg bones after G.A. Ilizarov

A study was made of reparative osteogenesis and the content of mineral bone components in 60 patients with spiral fractures of the leg bones during treatment by transosseous osteosynthesis. The time of maximum labelled pyrophosphate accumulation was determined by a degree of the initial dislocation of fragments: in the dislocation to the cortical layer it was noted on the 42nd day, by 1/3 on the 45th day, by 2/3 on the 50th day, to the cross section on the 60th day. The demineralization of bone fragments in the dislocation to the cortical layer was 34%, by 1/2 37%, by 2/3 41% and to the cross section by 44%. The labelled sulphuric colloid accumulation by bone marrow cells was maximal in minimal dislocations and decreased with growing dislocation
