Abstract:
In our experiment, strain guage was used to investigate the stress distribution in half-ring sulcated external fixator on fresh human tibia and the influence of the number and diameter of stainless steel pin and the compression at fracture ends on stress distribution. The conclusions are as follows: half-ring Sulcated external fixator has no significant influence on the stress distribution on intact human tibia, the rate of stress protection caused by external skeletal fixation is very small (?=1.486) and half-ring sulcated external fixation can be used to result in equal compression at fracture ends; increasing the number and diameter of pin will significantly increase the rate of stress-protection; compression external fixation can not only improve the stiffness of external fixation, but also reduce the rate of stress protection significantly.
