Curve progression in non-surgically treated patients with idiopathic scoliosis: a cohort study with 40-year follow-up.

Background And Purpose:  Treatment of idiopathic scoliosis in childhood aims to prevent curve progression. It is generally accepted that curves > 50° have the highest risk of progression, but less well described is what happens with mild to moderate curves. The aim of this study was to assess long-term curve progression and health-related quality of life (HRQoL) and compare thoracic and thoracolumbar/lumbar (TL/L) curves.

Dual test gas pulmonary diffusing capacity in patients with idiopathic scoliosis 40 years after diagnosis.

There is limited knowledge on diffusing capacity in scoliosis patients. It remains to be determined if impaired pulmonary diffusing capacity is mostly influenced by reduced alveolar-capillary membrane diffusing capacity (D), reduced pulmonary capillary blood volume (V) or both. This study aims to report findings from dual test gas pulmonary diffusing capacity for carbon monoxide and nitric oxide (D) with quantification of pulmonary diffusing capacity for carbon monoxide corrected for haemoglobin with a five s breath-hold (D) and nitric oxide with a five s breath-hold (D), D and V.

A Feasibility Study of a Controlled Standing Fulcrum Side-Bending Test in Adolescent Idiopathic Scoliosis.

: Spinal flexibility radiographs are important in adolescent idiopathic scoliosis (AIS) for clinical decision-making. In this study, we introduce a new method, the 'quantitatively controlled standing fulcrum side-bending' test (CSFS test). This is a feasibility study; we aimed to quantify the applied force and track the temporospatial changes in the spine specifically by measuring the continuous change in the Cobb angle (in degrees) during lateral bending.

MRI in early stages of adolescent idiopathic scoliosis indicates a neuro-osseous growth mismatch associated with curve progression.

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.

Two-Year Radiological Outcome of Adult Spinal Deformity Treated with Lumbar Pedicle Subtraction Osteotomy or Posterior Lumbar Interbody Fusion: A Propensity Score-Matched Analysis.

Objective: The purpose of this retrospective cohort study was to compare the 2-year radiological outcome and revision rates in patients with adult spinal deformity treated with either pedicle subtraction osteotomy (PSO) or posterior lumbar interbody fusion (PLIF), when PLIF was used to improve sagittal balance.

Methods: In 2016, PLIF was introduced at our institution as an alternative method when restoring lumbar lordosis. We analyzed 2 cohorts of patients with adult spinal deformity undergoing either PSO in 2010-2015 or PLIF in 2016-2020, retrospectively.
