Limb prostheses are designed to replace missing or absent anatomical limbs for the purpose of providing increased function or cosmesis. The goal of the prosthetist is to fit the patient with a prosthesis that best suits their needs and is able to maximize their rehabilitation potential while minimizing disability. Some of the issues that the prosthetist must consider when fabricating a prosthesis include the patient's level of amputation, the condition of their residual anatomy, and the potential impact other health problems may have on their prosthetic usage. Furthermore, the patient's age, gender, activity level, rehabilitation goals, vocational needs, and avocational desires must also be taken into account. The goal in the fitting of lower‐limb prostheses is generally to restore a person's ability to stand and ambulate, and the components are selected by the prosthetist according to the potential walking ability of the patient. Upper‐limb prostheses are used for reaching, grasping, holding, and positioning objects. Issues concerning the control and interfacing of the upper‐limb prosthesis with the body are of primary consideration. The latest technological advances in prosthetic limb components have been aimed at improving function and simplifying operation, with the goal of enabling users to move naturally and to effectively interact with the environment.
