Amputations at the level of the lower leg are called transtibial, i.e., made below the knee. In this case, the design of prostheses is simpler than that which also includes prosthetics of the knee joint. A significant difference is also in the design of the receiving sleeve – shortened prostheses are characterized by the absence of a thigh sleeve, which makes it advisable to use vacuum attachment.
Also, the prosthesis of the lower leg can vary greatly in the design of the feet – these can be either cosmetic feet that provide stable walking or special designs designed for running, jumping, lifting weights, equipped with shock absorbers and having an increased coefficient of adhesion to the surface, made of modern alloys.
The polymer knee cap and silicone liner provide vacuum attachment of the prosthesis to the stump. Sometimes an additional attachment in the form of a special femoral cuff is used, but this is associated with ensuring the stability of the knee joint in case of individual indications. The shape and size of the receiving sleeve for the stump and the soft silicone insert are determined individually. Due to the small volume of soft tissue (compared to the thigh), a very precise calculation and high requirements for the attachment site are required for the lower leg. It should in no way cause discomfort to the user, so more than one fitting may be required after manufacturing.
Such wide opportunities for prosthetics are provided by the modular technology of manufacturing. The modular lower leg prosthesis is a “construction set” assembled from standardized, high-quality parts into an individual device that is perfectly matched to the user in terms of size, fit and functionality. The height of the prosthesis can be adjusted with high precision, adjusting it during the fitting process to ensure a smooth, natural gait, thanks to the adjustment and connection device that connects the foot and the residual limb socket.
Cosmetic prostheses, are also used and ensure the good look and steady gait in urban environments.
The All-Ukrainian Center for Rehabilitation and Prosthetics “ZDOROVIA” offers high-quality lower leg prostheses made of components from well-known manufacturers. We cooperate only with the most trusted manufacturers Streifeneder, Teufel, OttoBock. In addition:
