Outline of Final Research Achievements |
The characteristics of spinal lesions and features related to cervical spine abnormalities in 12 patients with D4ST1-deficient Ehlers-Danlos syndrome were determined. In addition, observation of bone tissue obtained from patient surgical specimens and bone morphometry showed that bone turnover was reduced. Taken together, these results suggest that the pathogenesis of progressive spinal deformity in D4ST1-deficient Ehlers-Danlos syndrome may involve (1) reduced bone metabolic rotation without calcification abnormalities and (2) ligament laxity presumed to be caused by connective tissue weakness.
