From: Perioperative complications after surgical treatment in degenerative adult de novo scoliosis
The flow chart demonstrates patients with deformity surgery (n = 622) from 2007 until 2009 and the exclusion process of any type of scoliosis other than of degenerative adult de novo (DAD) scoliosis (n = 92). An extensive patient history was undertaken. If doubts arose, previous radiographic imaging was examined. Additionally, referral doctor and/or family physician were contacted to exclude other causes for scoliosis. Exclusion occurred when idiopathic (n = 412), neuromuscular (n = 68), congenital (n = 33) or vertebral fractures (n = 17) were answered with a “Yes” or radiographic images showed idiopathic or any scoliosis deformation other than DAD scoliosis
