Clinical analysis of surgical treatment for idiopathic scoliosis in adults / 中国矫形外科杂志

ABSTRACT

[Objective]To analyze the clinical and radiographic outcome of surgical treatment for idiopathic scoliosis in patients treated at the age of 20 years or older.[Methods]In this study,62 adult patients with idiopathic scoliosis who underwent surgery using pedicle screw instrumentation were followed up for 2 to 5 years,and the results were analyzed clinically and radiographically.[Results]The prevalence of pain requiring specific treatment decreased from 16% to 4%,and the pain relieve was reliably obtained in the older patients.Radiographically,the mean correction rate of Cobb's angle was 56% for both the thoracic and lumbar curves,whereas it decreased with the age increasing,especially in relation to the thoracic curve.The sagittal plane correction was satisfactory.[Conclusion]This study clarified different specific characteristics and problems in the surgical treatment of adult idiopathic scoliosis in different age groups.Pain is the most important indication for surgery in patients older than 40 years,and it has been improved reliably by surgery in most of these patients.On the other hand,the correction rate of Cobb's angle would be decreased with the increased age,the sagittal plane correction rate is not related to age.
