骨盆解剖参数“入射角”-垂直于骶骨板中部的线与连接骶骨板中部和双股轴中心的线之间的角度-已被证明与骶骨倾斜度和腰椎前凸密切相关，并确保个体经济的站立姿势。这对确定脊柱的矢状曲线很重要。入射角也被证明部分取决于骶骨的矢状解剖结构，这是在儿童时期学习站立和行走时建立的。本研究的目的是（1）确定骶骨和发病角之间的关系，（2）比较三个人群中的这些参数：年轻人、行走前的婴儿和脊椎前移患者。44名正常年轻人，32名尚未行走的婴儿和39名因峡部裂导致脊椎滑脱的患者接受了矢状面全脊柱X线摄影。使用J. Hecquet开发的骶骨二维研究图形表和软件来确定各种解剖和位置参数。采用均值比较检验、多重相关检验和偏相关检验。使用析因计划方法进行测量的可靠性研究。骶骨的矢状面解剖参数与骨盆的入射角参数有密切关系，因此与脊柱的矢状面平衡有密切关系。腰椎滑脱患者骶骨的解剖结构特殊，有些特征与婴儿相似，但更弯曲，入射角明显更大。腰椎滑脱的发生与入射角有密切关系。婴幼儿的各项参数均显著小于成人。由此可见，骶骨的矢状面解剖在脊柱矢状面平衡中起着关键作用。骶骨是骨盆不可分割的一部分，构成脊柱弯曲的未变形部分。生长过程中矢状曲线的组织可以通过观察骶骨来跟踪。腰椎滑脱组的骶骨与正常组不同，较大的入射角和骶骨倾斜度可能导致椎体滑脱。
The anatomic pelvic parameter "incidence" - the angle between the line perpendicular to the middle of the sacral plate and the line joining the middle of the sacral plate to the center of the bicoxo-femoral axis - has been shown to be strongly correlated with the sacral slope and lumbar lordosis, and ensures the individual an economical standing position. It is important for determining the sagittal curve of the spine. The angle of incidence has also been shown to depend partly on the sagittal anatomy of sacrum, which is established in childhood while learning to stand and walk. The purpose of this study was (1) to define the relationship between the sacrum and the angle of incidence, and (2) to compare these parameters in three populations: young adults, infants before walking, and patients with spondylolisthesis. Forty-four normal young adults, 32 infants not yet walking and 39 patients with spondylolisthesis due to isthmic spondylolysis underwent a sagittal full-spine radiography. A graphic table and the software for bidimensional study of the sacrum developed by J. Hecquet were used to determine various anatomic and positional parameters. Comparison tests of means, and multiple and partial correlation tests were used. A study of the reliability of the measurements using factorial plan methods was performed. The sagittal anatomic parameters of the sacrum were found to have a close relationship with the pelvic parameter of incidence angle, and therefore with the sagittal balance of the spine. The anatomy of the sacrum in spondylolisthesis patients is particular in that some features are much like those of young infants, but it is more curved and the incidence angle is significantly larger. There is a close relationship between angle of incidence and the slip of spondylolisthesis. All the parameters of young infants are significantly smaller than those of adults. It can be concluded that the sagittal anatomy of the sacrum plays a key role in spinal sagittal balance. The sacral bone is an integral a part of the pelvis and constitutes the undistorted part of the spinal curves. Organization of sagittal curves during growth can be followed up by looking at the sacrum. The sacrum in the spondylolisthesis group differs from the normal, and the greater angle of incidence and sacral slope in this group could predispose to vertebral slip.
