Platyspondyly in treated beta-thalassemia.
Flattening of the vertebral bodies with a platyspondyly appearance is described in 14 patients selected for evaluation of short stature from 106 patients affected by thalassemia major, who received an intensive transfusion regimen combined with continuous chelation therapy. The vertebral body height/width ratio was decreased at the level of all the investigated tracts, namely, cervical and/or dorsal and/or lumbar. The flattening of the vertebral bodies may be due to suppression of intramedullary hematopoiesis by a high transfusion regimen. The reduced intravertebral pressure due to disturbed hemopoiesis could cause weight-bearing and other biological stresses to provoke a reduction in vertebral body height.
