Sacroiliac joint (SIJ) pain has been recognized as a main source of pain in 13% to 30% of patients with low back pain. Although it is not clear how the pain is created, it is believed that alteration in the normal joint motion can contribute to development of sacroiliac pain. Thus understanding the kinematics and load sharing across the joint can help to understand the mechanisms for generation of SIJ pain. Despite various biomechanical studies on biomechanics of SIJ, there is no literature on biomechanical differences between male and female SIJs. Due to limitation of in vivo and in vitro studies in quantifying load-sharing and stress distribution patterns in the joint, finite element analysis is a useful tool to assess these biomechanical parameters. The validated finite element models of a male and female lumbar spine-pelvis were utilized to simulate anatomical flexion, extension, lateral bending, and axial rotation motions. The range of motion, stress distribution, load sharing across the SIJ and pelvis ligaments strain for intact, instrumented, and post-partum female model were computed and compared between male and female models. This study found that the female sacroiliac joint had relatively higher range of motion, stresses, and loads than male model at both sides of the joint. Unilateral stabilization significantly reduced the fixed and contralateral SI joint range of motion. Moreover, laterally placement of the implant and presence of threads on the implant provided higher control on the SIJ motion. The motion reduction at the SI joint after unilateral and bilateral fusions resulted in minimal change in motion at the adjacent lumbar levels for both male and female models. The implant shape characteristics and their placements played a major role in stresses on the bone and implant. In both unilateral and bilateral fusions, SIJ stabilization was primarily provided by the inferior and superior implants. The simulated post-partum period female pelvis showed that post-partum effect along with ligament laxity increased SIJ motion and stresses markedly. Female SIJ had higher mobility, stresses, and loads compared to male SIJ leading to higher chances of feeling pain across the joint. This could be a possible reason for higher incidence of low back pain in females.
