Summary
Low back pain is a common disorder, with a life time incidence of 80%. The argument that the Sacroiliac joint is the root cause of back pain is controversial. However clinicians worldwide believe that slight changes in mobility at the sacroiliac joint located between the sacrum and ilium of the pelvis is responsible for a variety of clinical conditions including the low back pain. This is a weight bearing joint and has an approximated restricted movement of up to about 4 degrees in rotation and 1.6mm in translation. Load carrying capacity to the joint is provided by strong Anterior, Posterior and interosseous ligaments, which also help to resist shear. Both the left and the right sacroiliac joints are dependent on each other and also on the pubic symphysis in the osteo-articular ring. In order to study the mechanical response of the joint cartilage, only one SI joint was considered. In our research work, we modeled the left side SI joint in Abaqus with a finite element mesh. The joint is composed of two regions, one for the sacral side another for the iliac side. Each side consists of a strong bony layer and a cartilage layer which is 1.8mm thick on the sacral side and 0.8mm thick on the iliac side. These cartilage layers are further divided into zones, with each zone having its unique stiffness properties. Mooney rivlin hyper elastic material was used to model the cartilage layer, as many researchers have proved that the data obtained from the real cartilage was in unison with mooney rivlin hyper elastic material. The research analyses the joint under different loading conditions and hence obtained results pertaining to various mechanical parameters to show deformation, contact pressure and stress within each layer of the cartilage. The mechanical response is evaluated at different orientations for a normal joint, Fibrillated Joint and an arthritic joint. As per the output requests suggested in ABAQUS, the .dat file was read into MATLAB which would record the data and plot the results in MATLAB for graphical representation and comparison. An approximation on how the cartilage material behaves under different loading and orientations have been obtained
