Prospective study.
To explore the application and potential clinical value of shear wave elastography (SWE) in assessing the biomechanical properties of paraspinal muscles in adolescent idiopathic scoliosis (AIS).
This study screened 30 AIS who visited our hospital between January 1, 2023, and January 4, 2024. Shear wave elastography (SWE) was used to measure the Young's modulus of the paraspinal muscles while the patients were seated in a neutral posture. The biomechanical properties of the paraspinal muscles were analyzed, and their correlation with the degree of scoliosis was explored.
The Young's modulus values of the bilateral erector spinae, quadratus lumborum, and psoas major muscles in AIS showed significant differences (P < 0.05). A significant correlation was found between the difference in Young's modulus values of the paraspinal muscles and the Cobb angle (P < 0.05). Specifically, the erector spinae had a negative correlation with the Cobb angle (r = - 0.410, P = 0.024), while the psoas major and quadratus lumborum had positive correlations (r = 0.852, P = 0.024; r = 0.419, P = 0.021).
The results show that in AIS, the stiffness of the erector spinae is higher on the convex side, while the psoas major and quadratus lumborum are stiffer on the concave side. The Cobb angle positively correlates with the stiffness of the psoas major and quadratus lumborum, and negatively with the erector spinae. SWE effectively evaluates paraspinal muscle properties in AIS, aiding scoliosis diagnosis and assessment.
前瞻性研究。
探讨剪切波弹性成像（SWE）在评估青少年特发性脊柱侧凸（AIS）患者椎旁肌生物力学特性中的应用及潜在临床价值。
本研究筛选了2023年1月1日至2024年1月4日期间来我院就诊的30例AIS患者。患者取中立位坐姿时，采用剪切波弹性成像（SWE）测量椎旁肌的杨氏模量。分析椎旁肌的生物力学特性，并探讨其与脊柱侧凸程度的相关性。
AIS患者双侧竖脊肌、腰方肌和腰大肌的杨氏模量值存在显著差异（P < 0.05）。发现椎旁肌杨氏模量值的差异与Cobb角之间存在显著相关性（P < 0.05）。具体而言，竖脊肌与Cobb角呈负相关（r = -0.410，P = 0.024），而腰大肌和腰方肌呈正相关（r = 0.852，P = 0.024；r = 0.419，P = 0.021）。
结果表明，在AIS中，凸侧竖脊肌的刚度较高，而凹侧腰大肌和腰方肌的刚度较高。Cobb角与腰大肌和腰方肌的刚度呈正相关，与竖脊肌呈负相关。SWE可有效评估AIS患者的椎旁肌特性，有助于脊柱侧凸的诊断和评估。
