title: [Platyspondylisis+ in beta-thalassemia major].
abstract: Platyspondylia was observed in 14 patients affected with thalassemia major (7 males and 7 females, age range: 10-18 years) who received an intensive transfusion regimen combined with continuous chelation therapy (desferrioxamine: 50-80 mg/kg daily). Height/width ratio was decreased at all the investigated tracts--i.e., cervical and/or dorsal and/or lumbar spine. The range of height/width ratio values was 0.41-0.55 at the 5th cervical body, 0.33-0.53 at the 8th dorsal body, 0.43-0.56 at the 12th dorsal body and 0.47-0.62 at the 2nd lumbar body. The flattening of the vertebral bodies seems to be due to the depletion of hematopoetic tissue determined by the high transfusion regimen. The reduced intramedullary pressure is thought to counteract neither weight-bearing nor other biological stresses, which might ultimately provoke the thinning of vertebral bodies.
