The aim of this study is to analyse the deep fasciae of limbs in order to evaluate the collagen and elastic fibre arrangement and the types of innervation. Histological and immunohistochemical stains were performed in 72 specimens. The deep fascia of the limbs is a sheath presenting a mean thickness of 1mm, formed by two to three layers of parallel collagen fibre bundles. In the adjacent layers, they show different orientations. Each layer is separated from the adjacent one by loose connective tissue, permitting the sliding of the collagen layers. Nerve fibres were found in all specimens, while muscular fibres were evidenced only in one specimen. The described structure permits the fasciae of the limbs to have a strong resistance to traction, even when exercised in different directions. The capacity of the different collagen layers to glide one on the other could be altered in cases of overuse syndrome, trauma, or surgery.
本研究旨在分析四肢深筋膜，以评估胶原纤维和弹性纤维的排列以及神经支配类型。对72个标本进行了组织学和免疫组织化学染色。四肢深筋膜是一层平均厚度为1毫米的鞘膜，由两到三层平行的胶原纤维束组成。在相邻层中，它们呈现出不同的方向。每层之间由疏松结缔组织分隔，使得胶原层能够滑动。在所有标本中均发现了神经纤维，而仅在一个标本中发现了肌纤维。所描述的结构使得四肢深筋膜即使在不同方向运动时也能对牵引力具有很强的抵抗力。在过度使用综合征、创伤或手术的情况下，不同胶原层之间相互滑动的能力可能会发生改变。
