ABSTRACT: Study Design. Retrospective clinical data analysisObjective. This study was conducted to retrospectively analyze the demographics, clinical presentation, and radiographic findings of ossification of posterior longitudinal ligament of the cervical spine in Korean patients in order to obtain a basis for further studies on and treatment of ossification of posterior longitudinal ligament (OPLL)Summary of Background Data. As the frequency of diagnosing the OPLL has been gradually increasing due to the increased importance and interest, it is important to understand the demographic characteristics of the disease.Methods. Of 222 patients diagnosed with OPLL of the cervical spine, 146 patients were evaluated. Demographic features such as age and gender, and clinical features in symptoms and treatments were analyzed and radiologic features observed from plain radiography, CT for 3D reconstruction, and MRI were investigated.Results. A total of 146 subjects consisted of 106 male and 40 female patients, which showed a male to female ratio of 2.65:1. The mean age of the subjects was 53.3 years. Neurological symptoms such as radiculopathy or myelopathy were observed in 109 patients (74.7%). 19.9% of the patients had not been diagnosed in plain radiography. Ossification of paraspinal ligaments was also accompanied in 86.3% of the subjects. Intramedullary high signal intensity in T2-weighted sagittal plane images of MRI was shown in 62 patients (42.5%). Concurrent herniated intervertebral disc was observed in 37 patients (25.3%).Conclusion. The demographics, clinical presentation, and radiographic findings of OPLL of the cervical spine in Korean were analyzed, which could be used as a basis for further study on and treatment of ossification of posterior longitudinal ligament. The classification method using plain radiographs has some limitation for disease treatment or prognosis prediction. For the exact diagnosis and classification of the OPLL, CT scan is more useful.
