Purpose: Our objective was to analysis the barycentremetry, obtained from the external envelope reconstruction of biplanar radiographs, in adolescent idiopathic scoliosis (AIS) and to determine whether assessing would help predict the distinction between progressive and stable AIS at the early stage.
Methods: A retrospective study with a multicentre cohort of 205 AIS was conducted. All AIS underwent a biplanar X-ray between 2013 and 2020.
Article Synopsis
- This study aimed to evaluate the odontoid-hip axis (OD-HA) angle in patients with mild scoliosis to predict whether adolescent idiopathic scoliosis (AIS) is progressing or stable.
- Researchers used biplanar X-rays from 2013 to 2020 to analyze the OD-HA angle in 205 AIS patients and 83 non-scoliotic controls, identifying key differences in alignment.
- The findings indicated that AIS patients are significantly more likely to have malalignment, suggesting the OD-HA measurement could help clinicians assess the stability of scoliosis in adolescents.
Article Synopsis
- The study investigates how spinal surgery for adolescent idiopathic scoliosis (AIS) affects spinal axial torque, which is critical in understanding spinal load distribution.
- It utilized a retrospective analysis of 29 AIS patients who underwent posterior spinal fusion in 2019, comparing preoperative and postoperative measurements against a reference group of asymptomatic individuals.
- Findings revealed significant reductions in Cobb angle and spinal axial torque post-surgery, but over 90% of patients still exhibited elevated torque levels, particularly at the upper end vertebra, indicating persistent issues postoperatively.
Purpose: Lumbar kyphosis occurs in approximately 8-20% of patients with myelomeningocele (MMC). The purpose of this article is to analyze the risks and benefits of vertebrectomy and spinal stabilization in MMC children with severe lumbar kyphosis and to establish treatment guidelines.
Methods: This is an IRB-approved retrospective analysis of 59 patients with MMC who underwent kyphectomy and posterior instrumentation in three centers.
Proximal Junctional Kyphosis in Modern Spine Surgery: Why Is it So Common?
Spine Surg Relat Res
March 2023
In the past few decades, proximal junctional kyphosis (PJK) has emerged as a new complication after instrumented spinal fusion in adult and pediatric spinal deformities. This phenomenon has occurred concomitantly with the rise of robust instrumentation techniques and enhancement of our abilities to obtain greater spinal deformity correction. The goal of this paper is to review the mechanical and biological causes of PJK and recommend prevention strategies.
