This study was designed to develop a machine learning (ML) model that predicts future Cobb angle in patients with adolescent idiopathic scoliosis (AIS) using minimal radiographs and simple questionnaires during the first and second visits. ⋯ The ML-based model using items commonly evaluated at the first and second visits accurately predicted future Cobb angles in female patients with AIS.

To determine the association of the ultrasound reflection coefficient index and other clinical parameters to predict curve progression in children with AIS. ⋯ This pilot study showed that curve progression is associated with the Risser sign, KA, and RC index. Other parameters and a more extensive clinical study should be combined to develop a higher-accuracy prediction model.

Thoracolumbar kyphosis (TLK) is frequently reported in children with achondroplasia. The combination of TLK and the narrow spinal canal in achondroplasia increases the risk of developing symptomatic spinal stenosis. However, there is no consensus on the optimal management of TLK. ⋯ TLK is highly prevalent in achondroplasia, necessitating careful monitoring. A wait-and-see policy with restrictions on unsupported sitting is recommended initially, but early bracing should be considered for more severe cases.

Basilar invagination (BI) represents a complex anomaly of the craniovertebral junction, characterized by the displacement of the odontoid process towards the foramen magnum. Current surgical interventions include anterior decompression and combined anterior-posterior decompression with posterior fusion. Traditional methods for odontoid resection encompass transoral, transnasal, and endonasal approaches. However, these techniques are fraught with significant risks. Furthermore, the restricted exposure provided by the endonasal corridor's anatomical limitations hampers surgical manipulation, prompting spine surgeons to seek alternative techniques. This report details a case of BI managed through an endoscopic posterolateral odontoidotomy, showcasing an innovative surgical approach. We aim to describe our experience in partially removing the odontoid via posterolateral approach with a novel endoscopic technique, preventing the need for additional approach and related complications. ⋯ Our findings demonstrate that partial or total resection of the odontoid process via a posterolateral approach is feasible using endoscopic techniques. The endoscopic posterolateral transmass odontoidotomy should be considered a viable alternative method and route for patients necessitating partial or total odontoidectomy.

The aim of this study is to assess inter-reader agreement of imaging findings and compare readers' assessment of image quality (IQ) and appearance of metal artifact (MA) in patients with spinal implants between 0.55T and 1.5T MRI. ⋯ Imaging patients with spinal hardware at 0.55T results in comparable inter-reader agreement for clinically-relevant imaging findings and equivalent or improved image quality compared to 1.5T.
