Abstract
Radiography, Multislice Computed Tomography (MSCT) and Magnetic Resonance Imaging (MRI) were used to examine 168 patients with lower limb shortening, bone deformity at different stages of limb lengthening using transosseous distraction osteosynthesis with the Ilizarov apparatus. Based on the findings an algorithm for examination of patients with limb shortening and deformity was improved and added at different stages of treatment. The algorithm must include standard polypositional radiography with data processing if needed, using software for quantitative assessment of optical density, updated MSCT and MRI techniques. Indications for MSCT were preoperative measurement of bone density, evidently impaired architectonics; and delayed consolidation, cysts and areas of low density in the regenerate bone during treatment. MRI should be produced after removal of the frame in patients with lengthy fixation period, with the purpose of assessing degree of bone restructuring at the distractional regenerate bone and quality of new bone to plan a programme of rehabilitation.
