The purpose of this study was to use MRI and CT to observe osteoporosis vertebral fracture (OVF) combined with endplate-disc complex (EDC) injury and to classify the degree of EDC injury according to the changes in EDC signal intensity and morphology on the images.
We investigated the incidence of EDC injury, observed the morphology and signal intensity changes of EDC injury using MRI and CT, and graded the injuries from 0 to 4 according to their severity. We compared whether there were differences in the degree of EDC injury among different vertebral fractures, bone mineral density(BMD), and severity of vertebral fractures.
A total of 479 patients were included in this study, of whom 321 had EDC injury adjacent to the fractured vertebral body. Among those, 158 cases were grade 0, 66 cases were grade 1, 72 cases were grade 2, 78 cases were grade 3, and 92 cases were grade 4. The degree of EDC injury associated with thoracolumbar vertebral fractures was more serious than that of EDC injuries associated with thoracic and lumbar vertebral body fractures. Vertebral fractures with severe osteoporosis were associated with more severe EDC injury. Additionally, the more severe the vertebral fracture, the more severe was the combined EDC injury.
This study found that the incidence rate of EDC injury reached 67.0%. Among patients with OVF, severe osteoporosis and severe fractures in the thoracolumbar segments were often associated with more severe EDC injury.
本研究旨在通过 MRI 和 CT 观察骨质疏松性椎体骨折（OVF）合并终板-椎间盘复合体（EDC）损伤，并根据图像上 EDC 信号强度和形态的变化对 EDC 损伤程度进行分类。
我们调查了 EDC 损伤的发生率，观察了 MRI 和 CT 上 EDC 损伤的形态和信号强度变化，并根据损伤的严重程度将其分为 0 至 4 级。我们比较了不同椎体骨折、骨密度（BMD）和椎体骨折严重程度之间 EDC 损伤程度的差异。
本研究共纳入 479 例患者，其中 321 例存在与骨折椎体相邻的 EDC 损伤。其中，0 级 158 例，1 级 66 例，2 级 72 例，3 级 78 例，4 级 92 例。胸腰椎骨折相关的 EDC 损伤程度较胸腰椎体骨折更严重。严重骨质疏松性椎体骨折与更严重的 EDC 损伤相关。此外，椎体骨折越严重，合并的 EDC 损伤越严重。
本研究发现 EDC 损伤的发生率为 67.0%。在 OVF 患者中，严重骨质疏松症和胸腰椎段严重骨折常与更严重的 EDC 损伤相关。
