To Determine Whether Maximal Rib Prominence Measured On Lateral Radiographs Can Be Used As A Surrogate To Rib Rotation Determined By Surface Tomography (Quantecscanning) In Assessment Of Spinal Rotation. Patients With Adolescent Idiopathic Scoliosis Underwent Plain Lateral Radiographs And Quantec Scans. Maximal Rib Prominence On The Lateral Radiograph Was Defined Pre- And Post-Operatively By Distance From Most Posterior Aspect Of The Rib To The Facet Joint And Instrumented Rod, Respectively. Rib Rotation Was Measured By Surface Tomography Quantec Scan Using The Suzuki Method. This Was Then Repeated At A Later Time And By An Additional Investigator To Assess Intra- Observer And Inter-Observer Variability. The Correlation Between Maximal Rib Prominence And The Suzuki Ratio Was Determined.Aim:
