Journal ArticleDOI
Adolescent Idiopathic Scoliosis: A New Classification to Determine Extent of Spinal Arthrodesis
Lawrence G. Lenke,Randal R. Betz,Jürgen Harms,Keith H. Bridwell,David H. Clements,Thomas G. Lowe,Kathy Blanke +6 more
TL;DR: A new two-dimensional classification of adolescent idiopathic scoliosis, as tested by two groups of surgeons, was shown to be much more reliable than the King system.
Journal ArticleDOI
Sagittal alignment of the spine and pelvis during growth.
TL;DR: Pelvic morphology, as measured by the pelvic incidence angle, tends to increase during childhood and adolescence before stabilizing into adulthood, most likely to maintain an adequate sagittal balance in view of the physiologic and morphologic changes occurring during growth.
Journal ArticleDOI
Sagittal spinopelvic balance in normal children and adolescents
TL;DR: Results from this study could be used as an aid for the planning of surgery in pediatric patients with spinal deformity in order to restore a relatively normal sagittal spinopelvic balance.
Journal ArticleDOI
Comparison of anterior and posterior instrumentation for correction of adolescent thoracic idiopathic scoliosis.
Randal R. Betz,Jürgen Harms,David H. Clements,Lawrence G. Lenke,Thomas G. Lowe,Harry L. Shufflebarger,Dezsö Jeszenszky,Bruno Beele +7 more
TL;DR: The 2-year postoperative results of a prospective multicenter study comparing the use of anterior instrumentation with that of posterior multisegmented hook instrumentation for the correction of adolescent thoracic idiopathic scoliosis are presented.
Journal ArticleDOI
Results of in situ fusion for isthmic spondylolisthesis.
Lawrence G. Lenke,Keith H. Bridwell,David Bullis,Randal R. Betz,Christy Baldus,Perry L. Schoenecker +5 more
TL;DR: This critical assessment of fusion grades is recommended to determine fusion success in this patient population of isthmic spondylolisthesis patients with a surprisingly low fusion rate.
