Introduction and objective: Adolescent idiopathic scoliosis (AIS) is a three-dimensional spinal deformity with lateral curvature of ≧10 degree measured by Cobb angle. Previous studies reported that ~30% of female AIS patients had systemic osteopenia which could persist beyond skeletal maturity and that was one of the important prognostic factors. The aim of this study is to investigate the incremental prognostic value of osteopenia on curve progression in AIS as defined...

Introduction and objective: Adolescent idiopathic scoliosis (AIS) is a structural spinal deformity characterized by 3D deformity with lateral curvature of ≧10° as measured by Cobb angle and is predominately seen in girlsaged between 10 and 16-years-old. Low bone mass has been found to be a significant prognostic factor for curve progression in AIS.In our hospital, computed assisted navigation is used for intraoperative pedicle screw placement...
