Purpose: To evaluate three-dimensional (3D) vertebra and disk shape changes over 2 years following anterior vertebral body tether (AVBT) placement in patients with idiopathic scoliosis (IS).
Methods: Patients with right thoracic IS treated with AVBT were retrospectively evaluated. 3D reconstructions were created from biplanar radiographs.
Objective: The purpose of this study was to assess L4-S1 inter-vertebral coronal motion of the unfused distal segments of the spine in patients with adolescent idiopathic scoliosis (AIS) after instrumented fusion with regards to postoperative time and fusion length, independently.
Methods: Coronal motion was assessed by standardized radiographs acquired in maximum right and left bending positions. The intervertebral angles were measured via digital radiographic measuring software and the motion from the levels of L4-S1 was summed.
Study Design: Reproducibility study of SterEOS 3-dimensional (3D) software in large, idiopathic scoliosis (IS) spinal curves.
Objective: To determine the accuracy and reproducibility of various 3D, software-generated radiographic measurements acquired from a 2-dimensional (2D) imaging system.
Summary Of Background Data: SterEOS software allows a user to reconstruct a 3D spinal model from an upright, biplanar, low-dose, X-ray system.
Objective: To define the current rate of postoperative surgical site infections (SSIs) in a large prospective series of surgical adolescent idiopathic scoliosis (AIS) cases.
Methods: A multicenter, prospective database of patients who underwent surgical correction of AIS was reviewed. Early SSIs were defined as occurring within 90 days after the index operation, as per the Center for Disease Control's definitions.
Study Design: Retrospective review.
Objective: To determine the association of patient characteristics and spinal curve parameters with Lenke curve types.
Summary Of Background Data: The Lenke curve classification may be used for surgical planning and clinical research.
Study Design: A cross-sectional study.
Objective: The purpose of this study was to assess intervertebral segmental and cumulative motion in the distal unfused segments of the spine in patients with adolescent idiopathic scoliosis after instrumentation as a function of the lowest instrumented level.
Summary Of Background Data: The implications of hyper- or hypomobility in the unfused segments of the spine after instrumentation are poorly understood.
Study Design: A multicenter study of changes in Scoliosis Research Society (SRS) outcome measures after surgical treatment of adolescent idiopathic scoliosis (AIS).
Objective: To evaluate changes in patient determined outcome measures between 2 and 5 years after AIS surgery.
Summary Of Background Data: Current surgical procedures have been shown to improve subjective measures in patients with AIS.
Does obesity affect surgical outcomes in adolescent idiopathic scoliosis?

Study Design: A retrospective review of surgical outcomes in adolescents with idiopathic scoliosis.
Objective: To determine if an association exists between body mass and surgical outcomes in adolescent idiopathic scoliosis (AIS).
Summary Of Background Data: Obesity has reached epidemic proportions globally.
Study Design: A retrospective chart review and radiographic analysis.
Objective: To evaluate the association between thoracic hyperkyphosis and patient quality of life measures as determined by the Scoliosis Research Society (SRS) outcomes instrument.
Summary Of Background Data: Although validated outcomes questionnaires (e.
Study Design: This research was part of a multicenter study of the surgical treatment of adolescent idiopathic scoliosis (AIS).
Objective: To compare the radiographic and perioperative surgical treatment outcomes of male AIS patients with female AIS patients.
Summary Of Background Data: The results of treatment in male patients with idiopathic scoliosis have not been widely reported.
