Abstract: An orthosis chosen from a venous support orthosis and an elastic venous compression orthosis, the orthosis including a ribbed top and a leg part, the ribbed top including an intermediate part extending the leg part, the stitch being different on each side of the boundary separating the leg part and the intermediate part, a welt extending the intermediate part and of a height less than 1.5 cm.

Abstract: An elastic venous compression orthosis has a top part and a leg part, the top part and the leg part having a top part knit thread and leg part knit thread, respectively, defining a network of knitted meshes, and a top part weft thread and leg part weft thread, respectively, the orthosis being characterized in that the top part has a reinforcement thread with an elongation at break, measured according to DIN 53834, of below 40% and a linear density of over 30 dTex.

Abstract: An elastic venous compression orthosis having a top part and a leg part, the top part and the leg part having a top part knit thread and leg part knit thread, respectively, defining a network of knitted meshes, and a top part weft thread and leg part weft thread, respectively, each weft thread having a core which is covered by means of a covering thread, the orthosis being characterized in that the core of the top part weft thread and the one or more covering threads of the top part weft thread are made of elastane, and the core of the top part weft thread has a linear density of less than 0.7 times that of the core of the leg part weft thread.

Abstract: An orthosis chosen from an elastic venous retention orthosis and an elastic venous compression orthosis is intended to treat a venous disorder of a lower limb of a patient in a service position in which it is fitted on the lower limb. The orthosis has a leg part, a ribbed top configured to maintain the orthosis in the service position, and a tab fixed on the ribbed top in such a way as to be accessible to the patient in the service position.
