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.

Methods: Patients were classified according to overall survival (OS): favorable corresponded to an OS ≥ 24 months, moderate corresponded to an OS of 6-24 months, and poor corresponded to an OS < 6 months. Multivariate Cox regression analyses were used to evaluate prognostic factors.
Article Synopsis
- * A study involving 33 AIS patients assessed the impact of 4D spinal reconstruction on their postural stability both before and after surgery, using a force plate to measure performance in eye-open and eye-closed positions.
- * Results showed that while postural stability temporarily decreased one week after surgery, significant improvements were observed two years post-operation, especially in the eye-closed condition, compared to preoperative levels.
Background: In full-endoscopic spine surgery via transforaminal approach (FESS-TF), the outside-in method facilitates treatment for various cases; however, the technique is difficult to perform. To facilitate this procedure, we developed a duckbill release technique. In this article, we aimed to introduce the details of this technique and investigate its effectiveness.

Methods: A total of 299 patients with ASD who underwent multi-segment posterior spinal fusion were registered in a multi-center database were investigated. Patient mobility status was assessed using walking aids and classified into five levels (1: independent, 2: cane, 3: walker, 4: assisted, and 5: wheelchair) preoperatively, at discharge, and after 2 years.
