This study analyzed the postoperative results of surgical treatment for thoracic and cervicothoracic myelopathy caused by ossification of the posterior longitudinal ligaments (OPLL) or ossification of the yellow ligaments (OYL) in 22 patients using magnetic resonance imaging (MRI), myelography and computed tomography (CT). Anterior procedures were performed in 11 patients for OPLL, while posterior approaches were adopted for the management of 11 patients for both OYL and OPLL combined with OYL lesions. Clinical symptoms were improved using both anterior and posterior techniques. MRI and myelo-CT studies, which show the direction of cord compression, the form and extent of the lesion, and the degree of thoracic kyphosis, are very useful when the surgical procedure for OPLL and OYL in the thoracic and cervico-thoracic spine is selected.
本研究使用磁共振成像（MRI）、脊髓造影和计算机断层扫描（CT）分析了22例因后纵韧带骨化（OPLL）或黄韧带骨化（OYL）导致胸段和颈胸段脊髓病的患者手术治疗的术后结果。11例因OPLL接受了前路手术，而11例因OYL以及OPLL合并OYL病变接受了后路手术。前后路技术均改善了临床症状。当选择胸段和颈胸段脊柱OPLL和OYL的手术方式时，显示脊髓压迫方向、病变形态和范围以及胸椎后凸程度的MRI和脊髓CT研究非常有用。
