Abstract：Objective To explore the pelvic marrow edema of sacroiliac joint and pubic symphysis at fullterm pregnant female before and after delivery based on Magnetic Resonance Image and its relationship with pelvic pain from pregnancy to postpartum, and to study effects of pregnancy and childbirth on pelvis. Methods We did retrospective investigation from January 2014 to January 2017 in the 97 cases fullterm pregnant female underwent 2 or 3 times pelvic MRI in Nanfang Hospital of Southern Medical University.MRI examination was performed at late term pregnancy, 42 days postpartum and/or 6-8 months postpartum. According to mode of delivery, they were separated to vaginal delivery group (72 cases) and cesarean group (25 cases).Recording whether there was marrow edema of the sacroiliac joint and pubic symphysis and whether there was pubic symphysis fracture on its MRI, and follow-ups were made in all patients about whether they had history of pelvic pain before and during pregnancy and postpartum by telephone. The pelvic MRI of 120 nulliparous female were collected as control.Results (1) After vaginal delivery, pubic symphysis bone marrow edema was higher than cesarean section primipara. (2) Bone marrow edema of sacroiliac joint and pubic symphysis can recover in postpartum 6-8 months. (3) The bone marrow edema of the sacroiliac joint were significantly related to pain of primipara's sacroiliacjoint, but marrow edema of pubic symphysis had no correlation with pubic symphysis pain, but pubic symphysis fracture was significantly correlated with its pain.Conclusion The bone marrow edema of sacroiliac joint is joint inflammation, and significantly associated with primipara's sacroiliac joint pain in late pregnancy and postpartum. So When dealing with primipara's sacroiliac joint pain we should pay enough attention to sacroiliac joint bone marrow edema.
