A retrospective study of 21 patients with idiopathic scoliosis who underwent endoscopic thoracoplasty was done. The objective of the study was to report and assess the morbidity and mid term outcomes of video-assisted thoracoplasty in idiopathic scoliosis. Patients with idiopathic scoliosis often present cosmetic complaints due to their rib deformity. This deformity may still exist after surgical correction of the main scoliotic curve. Endoscopic thoracoplasty has been reported as a safe method in limited cases of idiopathic scoliosis. Between 2002 and 2004, 21 patients underwent endoscopic anterior release and thoracoplasty for significant rib hump deformity associated with idiopathic scoliosis. Patients were operated on lateral position, with two endoscopic ports. Anterior release and rib resection were performed during the first stage, and instrumented posterior fusion was performed in a second stage. Patients were evaluated preoperatively, 1 week after surgery, 6 months after surgery and at their most recent follow-up with clinical and radiological measurement of the rib deformity. The mean age at surgery was 14.9 years old (range 13-17 years). The average Cobb's angle of the main scoliotic curve was 70 degrees (range 60 degrees -85 degrees). Average follow-up was 25 months (range 23-32 months). The mean number of resected ribs was five ribs (range 4-7) and the mean length of the resected rib was 4.2 cm (range 2.2-7 cm). Average operating time of endoscopic thoracoplasty (including anterior release) was 65 min (range 45-108 min). The mean preoperative height of rib hump deformity was 3.6 cm (range 2.5-5.5 cm). It was reduced to 1.5 cm at most recent follow-up. There was no significant thoracic pain necessitating medication postoperatively. No complications related to endoscopic anterior release and rib hump resection occurred in the series. Endoscopic thoracoplasty is a safe and reliable technique in idiopathic scoliosis. If indicated, the anterior release can be performed with video-assistance and the thoracoplasty can be performed on the same stage.

Intelligent measurement of adolescent idiopathic scoliosis x-ray coronal imaging parameters based on VB-Net neural network: a retrospective analysis of 2092 cases.

Background: Adolescent idiopathic scoliosis (AIS) is a complex three-dimensional deformity, and up to now, there has been no literature reporting the analysis of a large sample of X-ray imaging parameters based on artificial intelligence (AI) for it. This study is based on the accurate and rapid measurement of x-ray coronal imaging parameters in AIS patients by AI, to explore the differences and correlations, and to further investigate the risk factors in different groups, so as to provide a theoretical basis for the diagnosis and surgical treatment of AIS.
Methods: Retrospective analysis of 3192 patients aged 8-18 years who had a full-length orthopantomogram of the spine and were diagnosed with AIS at the First Affiliated Hospital of Zhengzhou University from January 2019 to March 2024.

Purpose: To investigate the relationship between spinal cord anatomy and the risk of curve progression in mild to moderate adolescent idiopathic scoliosis (AIS).
Methods: We prospectively included patients presenting with mild or moderate AIS (< 40 degrees). Irrespective of curve severity, patients underwent 3-dimensional MRI and were followed until skeletal maturity or surgery.
Enhancing Recovery in Severe Adolescent Idiopathic Scoliosis (AIS) Patients With Cobb Angle ≥90 Degrees Undergoing Single-staged Posterior Spinal Fusion (PSF): Evaluating the Feasibility of Rapid Recovery Protocol (RRP).

Department of Orthopaedic Surgery, National Orthopaedic Centre of Excellence for Research and Learning (NOCERAL), Faculty of Medicine, Universiti Malaya, Kuala Lumpur, Malaysia.
Study Design: Retrospective study.
Objective: To assess the feasibility and outcome of rapid recovery protocol (RRP) in severe adolescent idiopathic scoliosis (AIS) patients with Cobb angle ≥90 degrees underwent single-staged posterior spinal fusion (PSF).
Summary Of Background Data: Corrective surgeries in severe AIS patients entail a higher risk of prolonged operation, excessive bleeding, extended hospital stay, and higher complication rates compared with non-severe AIS patients.

Department of Orthopaedics & Traumatology, Haydarpasa Numune Training and Research Hospital, Istanbul, Turkey.
Background: The aim of this study is to examine the association between adding-on (AO) and disc degeneration(DD) of distal unfused levels in Lenke 3 C, 5 C, 6 C adolescent idiopathic scoliosis (AIS) patients with a follow-up of at least two years by comparing preoperative and postoperative magnetic resonance imaging (MRI).
Methods: 47 AIS patients (32 females and 15 males) with structural thoracolumbar/lumbar (TL/L) curves treated with long segment thoracolumbar fusion were retrospectively evaluated. Patients were divided into two groups according to the occurrence of the AO (AO and Non-AO groups).
Four-dimensional anatomical spinal reconstruction using pre-bent rods in thoracic adolescent idiopathic scoliosis.

A four-dimensional (4D) anatomical spinal reconstruction (ASR) technique and anatomical notch-free, pre-bent rods have been developed for thoracic adolescent idiopathic scoliosis (AIS) surgery. We aimed to evaluate the outcomes of ASR using notch-free rods through multiple comparisons with conventional methods, including the simultaneous double-rod rotation technique (SDRRT) and ASR using manually bent notched rods. Three consecutive series of 126 patients who underwent surgery for Lenke 1 AIS curves were prospectively followed up for 2 years after surgery.
