Myelodysplasia: the natural history of kyphosis and scoliosis. A preliminary report.

The results of this study support the concept that the levels of the bifid vertebral arch and of functional motor activity are significant influences on the development of scoliosis and kyphosis in patients born with myelodysplasia. 'Significant' degrees of scoliosis and kyphosis may appear at any time during life, but most frequently occur during late childhood or adolescence. Not all 'significant' curvatures require treatment, nor do all children with myelodysplasia and factors predisposing to kyphosis and scoliosis develop these complications. It is believed that the preliminary cumulative percentage curves presented in this study will be of value in counselling parents of afflicted newborn infants, and in planning the management of patients born with myelodysplasia.
