Abstract
The research was achieved in the center of prosthesis manufacturing ( Sadr Al– Qanat Factory for Prosthesis and Orthoses), and Baghdad Factory/Ministry of Health and Prosthesis and Orthoses workshop (Belong to Technical Medical Institute). The research made a study on a sample of (60) handicapped in the kind of partial foot amputation for the foot kind (Chopart).The material used in manufacturing the socket was plastic or leather or the two materials together. It was found that the maximum percentage of failure was (55%) for the socket made from plastic and the cause of failure was fracture where as the minimum percentage was (15%) for the socket that made from leather and the cause of failure was fracture. Either for the height of the socket It was found that the maximum percentage was (50%) for the socket of height with knee level and the cause of failure was fracture, where as the minimum percentage was (15%) for the socket of 1/3 distance between the knee and ankle joint and the cause of failure was fracture also. Either for the motion of ankle joint it was found that the maximum percentage was (60%) for the socket of no motion and the cause of failure was fracture where as the minimum value was (15%) for the socket of no motion but the cause of failure was the shape change of the socket.
