Summary:We reported the case of a 40-year-old man who had cervical myelopathy due to ossification of the ligamentum flavum accompanied with cervical spondylosis. The ossification of the ligamentum flavum was obscure in the plain radiograph and tomogram. But, the computerized tomogram showed the accurate diagnosis of the level of the spinal canal stenosis. The ossification of the ligamentum flavum seemed to be the major cause of spinal cord compression. The expansive laminoplasty was carried out with resection of the ossified ligamentum flavum. And the good result was obtained. Microscopic examination of the removed ligamentum showed not only a bony structure consisting of haversian systems but also calcified tissues in the ligamentum flavum.
