Modular hip prosthesis, including for congenital underdevelopment

Modular hip prosthesis. The moulding part of the cosmetic lining is modular soft polyurethane. Cosmetic lining covering - orthopaedic perlon stockings. Trial sleeve made of easily mouldable plastic from a residual limb impression. Double permanent socket: supporting and stump receiving socket with fitting for hip flexion contracture. Material of the permanent socket: injection moulded laminate based on acrylic resins. Silicone sheaths are used as an insertion element, fixation using a two-point fixation system. material: titanium. Single-axis knee joint with braking mechanism throughout the entire support phase, with dependent mechanical regulation of the flexion-extension phases and protective cover, the transfer phase is regulated by axial friction and the force of springs integrated in the ankle joint. Foot with all-round mobility due to titanium RSU roll over on a ring-shaped rubber shock absorber.
