Coonrad Classification Paper

Description: Spine. 1998 Jun 15;23(12):1380-91. Links A logical coronal pattern classification of 2,000 consecutive idiopathic scoliosis cases based on the scoliosis research society-defined apical vertebra.Coonrad RW, Murrell GA, Motley G, Lytle E, Hey LA.
CONCLUSION: Two thousand consecutive idiopathic coronal curve patterns separated into eleven readily identifiable types, and incorporating the widely referenced five King types, makes recognition simple for purposes of identification and communication. Sagittal and 3D factors excluded from this classification are equally important in the process of treatment decisions. Apical frequency data determined in this study lends credence to Scoliosis Research Society definitions for idiopathic curve patterns.
