Recent years have seen the development of various classifications of muscle injuries, primarily based on the topographic location within the bone-tendon–muscle chain. This paper proposes an enhanced nomenclature for muscle injuries that incorporates histoarchitectural definitions alongside topographic classifications, emphasizing the importance of connective tissue damage characterization. A detailed understanding of the distinct anatomical and histological characteristics of tendon, aponeurosis, and fascia is essential for consistent terminology. Tendons, aponeuroses, and fasciae, while all composed of dense connective tissue, differ in collagen fiber orientation and structural organization. Tendons feature longitudinally aligned fibers suited for high tensile forces and muscle-to-bone connections. Aponeuroses have perpendicular collagen fiber layers, allowing for force distribution and support for both longitudinal and transverse traction. Fasciae exhibit loosely organized fibers providing flexibility and movement between muscles. The continuity and differences within the musculotendinous frameworks, particularly at the musculotendinous junction (MTJ), elucidate the higher frequency of injuries at these sites compared with tendons, highlighting the MTJ's role as a stress-absorbing 'safety valve.'

近年来，肌肉损伤的各种分类得到了发展，主要基于骨-肌腱-肌肉链内的地形位置。本文提出了一种增强的肌肉损伤命名法，将组织结构定义与地形分类相结合，强调了结缔组织损伤表征的重要性。详细了解肌腱、腱膜和筋膜的不同解剖学和组织学特征对于术语的一致性至关重要。肌腱、腱膜和筋膜虽然都由致密的结缔组织组成，但在胶原纤维方向和结构组织上有所不同。肌腱具有纵向排列的纤维，适用于高拉伸力和肌肉与骨骼的连接。Aponeuroses 具有垂直的胶原纤维层，允许力分布并支持纵向和横向牵引。筋膜表现出组织松散的纤维，在肌肉之间提供灵活性和运动。肌腱框架内的连续性和差异，特别是在肌腱交界处 （MTJ），阐明了与肌腱相比，这些部位的损伤频率更高，突出了 MTJ 作为吸收应力的“安全阀”的作用。
