We report two cases of calcification of the ligamentum flavum of the cervical spine.Case1: A 68-year-old woman presented a history of numbness of the limbs and gait disturbance. Computerized tomograph showed calcification of the ligamentum flavum from C3 to C6.Case2: A 68-year-old woman presented a history of numbness and pain of the bilateral hands. She had calcification from C5 to C7 and suffered from diabetes mellitus.We treated both cases with open-door laminoplasty and removed the mass. We analyzed the mass of case 2 with X-ray microanalyzer and found that it consisted of hydroxyapatite.Calcification of the ligamentum flavum of the cervical spine is a serious disease with severe myelopathy.
