Abstract:
Objective To find out the character of the its strain distribution. Methods We use five fresh cadaver sacroiliac joints of male adults. We fixed the samples in the CT. We chose the same point of the joints and measure the CT values . Result The bone CT values of the sacroiliac joints and the same slide distributes in a curve from the anterior of the joint to the posterior. Conclusion The density of the bones are directly related with the strains. So the strain distribution on the sacroiliac joint surface is similar to the CT value distribution. This is similar to the result we get with tri- dimentional finite elements study of the sacroiliac joint.
