Multicenter Study Comparative Study
Restoration of thoracic kyphosis after operative treatment of adolescent idiopathic scoliosis: a multicenter comparison of three surgical approaches.
Multicenter analysis of 3 groups of patients who underwent surgical treatment for adolescent idiopathic scoliosis (AIS). OBJECTIVE.: To evaluate 3 surgical approaches to determine the modality that has the greatest influence on improving thoracic kyphosis. ⋯ ASFI is the best method to restore thoracic kyphosis when compared with posterior approaches using only hooks or a hybrid construct in the treatment of thoracic adolescent idiopathic scoliosis.

Multicenter Study Comparative Study
Comparison of compensatory curve spontaneous derotation after selective thoracic or lumbar fusions in adolescent idiopathic scoliosis.
Retrospective review of a multicenter prospectively collected series of adolescent idiopathic scoliosis (AIS) patients. ⋯ 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.

Multicenter Study
Radiographic predictors for the development of myelopathy in patients with ossification of the posterior longitudinal ligament: a multicenter cohort study.
A multicenter cohort study was performed retrospectively. ⋯ Static and dynamic factors were related to the development of myelopathy in OPLL.
