3-基于磁共振图像（MRI）的三维骨盆模型可用于研究怀孕期间和分娩后改变骨盆排列的准确性和具体情况。很少有研究使用三维骨盆模型来研究怀孕期间和分娩后骨盆排列的变化。本病例报告记录了使用基于MRI的三维（3D）骨盆模型在妊娠晚期和分娩后骨盆排列的变化。这是一份纵向观察病例报告。一名妇女在妊娠28周和39周以及分娩后4周和72周接受MRI成像。从妊娠第28周开始，在第39周观察到两种无名动物的内部、前部和向下旋转更大。与妊娠第39周相比，在分娩后第4周观察到两个无名氏的内部，前部和向下旋转减少。我们报告了日本首例在怀孕期间和分娩后使用基于MRI的3D骨盆排列模型测量骨盆排列变化的病例。此病例提示耻骨区改变较小，骶髂关节前部分离较大。在一名无骨盆疼痛的日本产妇中观察到两个无名指的内旋、前旋和下旋。
3-dimensional pelvic models based on magnetic resonance images (MRI) can be used to investigate accuracy and specifics of changing pelvic alignment during pregnancy and after childbirth. Few studies have investigated changes of pelvic alignment during pregnancy and after childbirth using three-dimensional pelvic models. This case report documents the changes of pelvic alignment during late pregnancy and after childbirth using MRI-based three-dimensional (3D) pelvic models. This was a longitudinal observation case report. A woman was imaged with MRI at 28 and 39 gestational weeks, as well as 4 and 72 weeks after childbirth. Greater internal, anterior, and downward rotation of both innominates at week 39 was observed from that at gestation week 28. Decreased internal, anterior, and downward rotation of both innominates at week 4 after child birth was observed compared with that at gestation week 39. We report the first case in Japan of changes of pelvic alignment measured using an MRI-based 3D pelvic alignment model during pregnancy and after child birth. This case suggests that the small changes of pubic area and greater separation of anterior portions of sacroiliac joints. Internal, anterior, and downward rotation of both innominates was observed in a Japanese primipara woman having no pelvic pain.
