Premature epiphyseal fusion and extramedullary hematopoiesis in thalassemia.
The main skeletal abnormalities in beta-thalassemia are widening of medullary spaces, rarefaction of bone trabeculae, thinning of cortical bone, and perpendicular periosteal spiculation. Premature epiphyseal fusion (PEF) and extramedullary hematopoiesis (EH) are found, though more rarely. The incidence of PEF and EH in 64 patients affected by beta-thalassemia is reported. The different incidence of such complications in thalassemia major and intermedia is reported, and a possible correlation with transfusion regimen is also considered.
