摘要
引用本文:Kayser F, Bori E, Armillotta N, Innocenti B, Hontoir F, Vandeweerd JM。羊髌骨肌腱剪切波速与拉伸试验刚度的相关性研究。临床与生物医学研究档案6(2022):248-259。摘要背景:肌腱损伤在男性中非常常见,愈合过程往往缓慢且不完整,现有的治疗方案令人不满意。机械性能如硬度可以反映组织愈合的进展。不幸的是,由于现有的传统生物力学测试方法的侵入性,这些测量不能在体内记录。SWE可以在体内用于研究肌腱的力学特性。材料与方法:对6只健康母羊的12条髌骨肌腱进行体内常规超声、彩色多普勒超声和SWE检查,并在体外进行单轴检查。结果:12根肌腱的平均刚度值为45.69 N/mm (SD±14.56)。平均横波速度为6.27 m/s (SD+/-0.6)。横波速度与年龄呈正相关(r=0.137, p=0.79),而刚度与SWV呈正相关(r=0.87;p = 0.02)。结论:SWE可以代替肌腱的生物力学性能,并且可以在体内进行。它可能是一个有用的成像工具,在疾病进展和愈合随访的背景下。本研究获得的SWV值可作为进一步研究羊模型髌骨肌腱的基线值。
