Comparison of Compensatory Curve Spontaneous Derotation After Selective Thoracic or Lumbar Fusions in Adolescent Idiopathic Scoliosis

Axial plane rotational correction of the unfused minor curve in patients undergoing selective fusions does occur. Significant spontaneous correction of a thoracic rib hump after a selective lumbar fusion should not be anticipated, whereas an approximate 50% reduction in the lumbar prominence was the average after selective thoracic fusions.
