Adolescent idiopathic scoliosis (AIS) affects up to 3% of the population. It can be stratified by curve type according to the Lenke classification. This classification system incorporates curve magnitude, flexibility, the lumbar modifier, and the sagittal plane. The Lenke classification serves as a guide for selection of levels for surgical treatment of AIS. Surgical treatment of AIS includes anterior and posterior approaches; most AIS is treated through a posterior approach. Surgical goals include maximizing correction in the coronal, sagittal, and axial planes.

With the emergence of numerous classifications, surgical treatment for adolescent idiopathic scoliosis (AIS) can be guided more effectively. However, surgical decision-making and optimal strategies still lack standardization and personalized customization. Our study aims to devise proper deep learning (DL) models that incorporate key factors influencing surgical outcomes on the coronal plane in AIS patients to facilitate surgical decision-making and predict surgical results for AIS patients.

Study Design: Retrospective review of a prospectively collected single-center adolescent idiopathic scoliosis (AIS) database.
Objective: To evaluate the outcomes of single-sided thoracic anterior vertebral body tethering (VBT) versus bilateral thoracic/thoracolumbar VBT for the treatment of Lenke 1C type curves, as well as the outcomes of Lenke 1A/B curves compared to 1C curves.
Background: Lenke 1C curves can be successfully treated with selective thoracic fusion alone.
2D and 3D Classification Systems for Adolescent Idiopathic Scoliosis: Clinical Implications and Technological Advances.

Classification systems for Adolescent Idiopathic Scoliosis (AIS) play an important role in guiding both surgical planning and conservative treatments. Traditional 2D classification systems, such as the Lenke, King and Lehnert-Schroth classifications, have been widely used for the clinical diagnosis and treatment of scoliosis. However, with the growing understanding of the three-dimensional nature of scoliosis and advancements in 3D reconstruction technologies, 3D classification systems are gaining increasing attention.

Background: Adolescent idiopathic scoliosis, a complex three-dimensional spine deformity, presents a formidable challenge for orthopedic residents in understanding its anatomy and surgical strategies. The aim of this study is to investigate the impact of three-dimensional printing (3DP) models in enhancing the comprehension of adolescent idiopathic scoliosis among orthopedic residents.
Methods: Forty orthopedic residents were randomly divided into two groups, the first group received lectures that were augmented with 3DP models illustrating five cases of adolescent idiopathic scoliosis, along with corresponding X-ray and CT images.
Correction of L5 Tilt in 2-Row Vertebral Body Tethering Versus Posterior Spinal Fusion for Adolescent Idiopathic Scoliosis.

Department of Orthopaedics, NYU Langone Orthopedic Hospital, New York, NY.
Study Design: Single-center retrospective cohort study.
Objective: To compare the correction of fractional curve and L5 tilt in 2RVBT versus PSF with LIV in the lumbar spine.
Summary Of Background Data: Vertebral body tethering, an AIS fusion-alternative, avoids rigid constructs, allowing for lower instrumented vertebra (LIV) selection.
