Rare Hereditary Abnormal Bone Hyperplasia and Ossification of the Yellow Ligament Complicated by Thoracic Spinal Stenosis.

We report a rare case of familial inherited abnormal bone hyperplasia and ossification of the yellow ligament complicated by spinal stenosis. Complete reconstruction of stability and spinal cord decompression were achieved by posterior total laminectomy, fusion, and internal fixation. We cannot clearly describe the inheritance characteristics of the disease. Although the risk of surgical treatment is high, it is still necessary to perform surgery, and the effect of the operation is substantial.
