■在这项研究中,目的描述退行性颈椎后凸畸形(DCK)合并脊髓型颈椎病(CSM)的影像学特点,探讨DCK与脊髓功能障碍的关系。
■总共,本研究回顾性分析了2017年9月至2022年8月在本中心住院的90例CSM患者,然后将其分为后凸畸形组和非后凸畸形组。病人的人口统计学,临床特征,并获得了放射学数据,包括性别,年龄,疾病的持续时间,颈椎日本骨科协会(JOA)评分,宫颈前凸(CL),椎间隙的高度,椎体楔入程度,骨赘形成的程度,椎间盘突出程度,脊髓压迫程度,和脊髓的前后直径。在后凸组中,后凸段,后凸的顶点,记录节段后凸角度。还比较了两组之间的放射学特征。对不同脊髓压迫类型进行相关性分析。
■根据我们的发现,后凸畸形组的患者表现出更明显的椎体楔入,更严重的脊髓前部压迫,椎间盘突出程度更高,而与非后凸畸形组相比,脊髓的后部压迫相对较轻。CL与脊髓压迫的类型有关,由于颈椎后凸畸形是脊髓前路受压的独立危险因素。
■DCK可能在脊髓功能障碍的发病机制中起重要作用。在DCK患者中,确定前柱支撑较少,并且存在更严重的前脊髓压迫。对于患有DCK的CSM患者,应首选前路。
UNASSIGNED: In this study, we aim to describe the radiological characteristics of degenerative cervical kyphosis (DCK) with cervical spondylotic myelopathy (CSM) and discuss the relationship between DCK and the pathogenesis of spinal cord dysfunction.
UNASSIGNED: In total, 90 patients with CSM hospitalized in our center from September 2017 to August 2022 were retrospectively examined in this study; they were then divided into the kyphosis group and the nonkyphosis group. The patients\' demographics, clinical features, and radiological data were obtained, including gender, age, duration of illness, cervical Japanese Orthopaedic Association (JOA) score, cervical lordosis (CL), height of intervertebral space, degree of wedging vertebral body, degree of osteophyte formation, degree of disc herniation, degree of spinal cord compression, and anteroposterior diameter of the spinal cord. In the kyphosis group, kyphotic segments, apex of kyphosis, and segmental kyphosis angle were recorded. Radiological characteristics between the two groups were also compared. Correlation analysis was performed for different spinal cord
compression types.
UNASSIGNED: As per our findings, the patients in the kyphosis group showed more remarkable wedging of the vertebral body, more severe anterior compression of the spinal cord, and a higher degree of disc herniation, while the posterior
compression of the spinal cord was relatively mild when compared with the nonkyphosis group. CL was related to the type of spinal cord
compression, as cervical kyphosis is an independent risk factor for anterior spinal cord
compression.
UNASSIGNED: DCK might play a vital role in the pathogenesis of spinal cord dysfunction. In patients with DCK, it was determined that the anterior column is less supported, and more severe anterior spinal cord
compression is present. The anterior approach is supposed to be preferred for CSM patients with DCK.
