The work is based on the analysis of the results of radionuclide examination and treatment of 14 patients with ununited tractures and pseudoarthroses of the forearm bones. Treatment was accomplished by means of external fixation apparatuses which in comparison with intramedullary and epiosseous osteosynthesis provide a better stability of the site of bone injury and create ortimal biomechanical conditions for consolidation of ununited fractures and pseudoarthroses of the forearm bones. Radionuclide examination was conducted before the treatment to determine the initial activity of reparative regeneration in the zone of the pseudoarthrosis and the adjacent healthy regions, 2-3 weeks after perosseous osteosynthesis when the bone fragments were reduced and the compression or distraction regimen was established, and before removal of the apparatus when consolidation of the pseudoarthrosis was demonstrated radiologically. This made it possible to control the activity of reparative regeneration during treatment and to introduce corrections, if necessary. The radionuclide method is preferable to the radiological method in the intermediate stages of treatment not only because of the lesser exposure of the patient to radiation but because of the higner informativeness.
这项工作基于对14例前臂骨不愈合骨折和假关节患者的放射性核素检查及治疗结果的分析。治疗采用外固定器械完成，与髓内和骨膜外骨固定相比，外固定器械能为骨损伤部位提供更好的稳定性，并为前臂骨不愈合骨折和假关节的愈合创造最佳生物力学条件。在治疗前进行放射性核素检查，以确定假关节区域及相邻健康区域修复性再生的初始活性；在经皮骨固定术后2至3周，当骨折碎片复位并确定加压或牵引方案时进行检查；在影像学显示假关节愈合且拆除器械前进行检查。这使得在治疗过程中能够控制修复性再生的活性，并在必要时进行调整。在治疗的中间阶段，放射性核素方法优于放射学方法，这不仅是因为患者受到的辐射暴露较少，还因为其信息量大。
