Despite growing interest in retinacular structure and function, a\udcomprehensive analysis is still lacking. For some authors, they are\udsimple reinforcements of the fascia, while for others they are distinct\udstructures. Postmortem specimens taken from the antebrachial\udfascia (AF) and flexor retinaculum carpi (FR) of 20 upper limbs were\udanalyzed with histological (H.E., Weigert-van Gieson, azan-Mallory)\udand immunohistochemical (anti-S100) stains. The study demonstrated\udthat the AF is formed by numerous layers of collagen fiber\udbundles and some elastic fibers. In each layer, the bundles are parallel\udto each other, whereas adjacent layers show different orientations.\udEach layer is separated from the adjacent one by a thin layer\udof loose connective tissue. The FR is not separable from the AF by\uddissection but presents different histological characteristics: the collagen\udfiber bundles are thicker, while the elastic fibers are almost\udabsent. Muscular fibers from thenar and hypothenar eminences\udinserted into the FR. Both the AF and the FR showed an abundant\udinnervation, mainly constituted by free nerve endings in the AF and\udby Ruffini and Pacini corpuscles in the FR. Thus, the FR, although in\udcontinuity with AF, may be considered for its peculiar structure and\udtype of innervation as a specific anatomical entity
