Objective: To determine the course of scoliosis in β-thalassemia and to compare the findings with those of patients with idiopathic scoliosis.
Methods: Forty-three patients with β-thalassemia were reexamined clinically and radiologically (anteroposterior and lateral roentgenograms) 10 years after the initial examination for scoliosis. The patients -19 males and 24 females- had a mean age + SD of 22.7 + 5.5 years (range 14 to 39 years).
Results: At the initial examination as well as at the follow-up examination 10 years later there were 9 patients without scoliosis and 34 (79%) with curves of at least 5o. Except for one patient with scoliosis of 85o at the second examination, curves in patients with scoliosis did not exceed 20o. Twelve (27.9%) patients had curves >10o, at the initial examination and 15 (34.9%) at the follow-up examination (p>0.3). “De novo” scoliosis of 10o or more evolved in 3 patients, curves of less than 10o progressed to curves of 10o or more in 4 patients, scoliosis of 10o or more resolved in one and improved in 3 patients. Degree and location did not differ significantly between initial and follow-up examination (t=1.02, p>0.31, x2=0.7, p>0.3, respectively). The ratio males: females at the initial and follow-up examination was 0.9 and 1.1, respectively.
Conclusion: Scoliosis in β-thalassemia is a different entity than idiopathic scoliosis: It appears early in childhood1, affects equally males and females, curves do not usually exceed 20o and prognosis is good, in contrast to idiopathic scoliosis, because curvatures do not usually progress.
