Objectives : This study was designed to find The characteristics of the Moire topography in patients of HIVD of Cx-spine. Methods : The Moire topography using IBS(Intek-plus Body Scanner 2000, Seoul, Korea) were obtained in 688 people of control group and 105 patients of HIVD of Cx-spine. Each values were studied to determine the difference between controls and patients. Results : There were significantly difference between controls and patients in thoracic ratio, lumbar ratio, top of the thoracic depth ratio, top of the lumbar depth ratio, Z axis distance and DZ/DY. Conclusions : There were increase of the thoracic kyphosis and lower position in top of the thoracic kyphosis in patients of HIVD of Cx-spine than controls.
