Operative results of adolescent idiopathic scoliosis in Lerdsin Hospital.

ABSTRACT

OBJECTIVE: Evaluate the results of the posterior instrumentation for the correction of adolescent idiopathic scoliosis (AIS) in Lerdsin Hospital. MATERIAL AND METHOD: A retrospective study was conducted to determine the effectiveness of surgical treatment of idiopathic scoliosis in Lerdsin Hospital. The pre-operative, immediate post operative, and the most recent follow-up (minimum 2 years) x-ray of 17 patients were evaluated for curve correction and spinal balance. RESULT: The present study found that the curvatures in thoracic King type II and III were corrected by about 58% post operatively. The curve progressed 3 degrees (5%) at the end of 2 years. For lumbar curve in King types I and II, there was the correction of 51% and 59%. After 2 years, the curve progressed around 6 degrees (7%) and 8 degrees (14%). Trunk balance was corrected by 60% in King type III. Degrees of thoracic kyphosis was decreased about 4 degrees. CONCLUSION: Frontal and sagittal thoracic and lumbar curve correction can be satisfactorily obtained by posterior spinal correction with instrumentation.
