For compression fracture, vertebral body height loss (VBHL) and kyphotic angle (KA) are two important imaging parameters for determining the prognosis and appropriate treatment. This study used previous measurement methods to assess the degree of VBHL and KA, compare and examine differences between various measurement methods, and examine the correlation between relevant measurement parameters and intravertebral cleft (IVC) in the vertebral body. The radiographic images (lateral view of the T-L spine) of 18 patients with a single-level vertebral compression fracture were reviewed. We measured 9 characteristic lengths and angles on plain radiographs, including anterior vertebral height (AVH) and AVH of the adjacent upper and lower levels, middle vertebral height (MVH) and MVH of the adjacent upper and lower levels, posterior vertebral height (PVH), and vertebral body width, and assessed 6 parameters, including vertebral compression ratio (VBCR), percentage of anterior height compression (PAHC), percentage of middle height compression (PMHC), kyphotic angle (KA), calculated kyphotic angle (CKA), and IVC. The results showed that VBCR is a simple and rapid method of VBHL assessment, but it may result in an underestimation of the degree of VBHL compared to PAHC. When or , the probability of IVC occurring on the vertebral body was higher which means the higher risk of vertebral body instability. The results of this study could provide a reference for surgeons when using imaging modalities to assess the degree of vertebral body collapse.

椎体压缩性骨折中椎体塌陷程度的不同放射学测量参数评估。

对于压缩性骨折，椎体高度损失（VBHL）和后凸角（KA）是确定预后和适当治疗的两个重要影像学参数。这项研究使用以前的测量方法来评估VBHL和KA的程度，比较和检查各种测量方法之间的差异，并检查相关测量参数与椎体内椎体裂隙（IVC）之间的相关性。回顾了18例单水平椎体压缩性骨折患者的影像学检查（TL脊柱的侧视图）。我们在平片上测量了9个特征长度和角度，包括邻近的上下水平的前椎高（AVH）和AVH，邻近的上下水平的中椎高（MVH）和MVH，后椎高（PVH） ，和椎体宽度，并评估了6个参数，包括椎骨压缩比（VBCR），前高度压缩百分比（PAHC），中高度压缩百分比（PMHC），后凸角（KA），计算后凸角（CKA）和IVC。结果表明，VBCR是一种简单而快速的VBHL评估方法，但与PAHC相比，它可能导致VBHL程度被低估。什么时候 要么 ， IVC发生在椎体上的可能性更高，这意味着椎体不稳定的风险更高。这项研究的结果可以为外科医生使用影像学方法评估椎体塌陷程度提供参考。
