Combined external osteosynthesis in treatment of forearm long bones fractures and its consequences
The authors observed the stages of developing of optimal combined (pin-wire) external fixation assemblies for forearm long bones fractures. Using 3-D paramethric modeling in software complex Solid Works the rigidity of bone fragments fixation in system «forearm skeleton + external fixation device» (105 series of experiments). Computer model adequacy is proved in experiments on cadaver material (15 series of experiment). The assemblies which provide good reduction capabilities while minimal number of transosseus elements, the smallest frame sizes and have the opportunity of module transformation are determined. They are approbated in treatment of 57 patients. Good and excellent results are achieved in 96 % of cases.
