ABSTRACT

Introduction: Hip disarticulation is performed by surgeons to prevent the growth of malignant diseases in cases that can not be treated conservatively. There is a possibility that the disarticulation may be caused by a traumatic accident involving one or both lower limbs.
Objective: to modify the design of a prosthesis for people with muscular tension problems, for heavy loads and repetitive movements, to be used in people with unilateral or bilateral hip disarticulation, starting from the patent of invention.
Methods: The design was made taking into account displacement similar to the human locomotor system, comfort, possible lesions in bony prominences, repetitiveness and low cost. To guarantee the least impact on the bone prominence, reducing the risk of rupture or ulcers, a 3D scanner with pressure sensors was used to correctly distribute the pressure over the whole hip prominence.
Results: The proposed system resulted in an alternative for people with mobility limitations in the lower limb allowing a more natural movement and thus improving the quality of life of this type of patients. The technique allowed the user a high level of independence in situations of loss of the lower limbs.
Conclusions: The study focused on the modification of a lower limb prosthesis used for people with low muscle tone or repetitive activities to a system for people with bilateral hip disarticulation or loss of a single lower limb.
