Abstract: A weight bearing brace for a patient having femur or hip joint trouble has an upper socket removably attached to the periphery of an upper part of a thigh; a lower socket removably attached to the periphery of a lower part of the thigh; connectors for connecting the upper and lower sockets to each other, bearing patient's weight, and maintaining a required space between the upper and lower sockets; and a pelvis supporter disposed at an upper end of the upper socket, to substantially receive the weight of the upper half of the patient. The patient with the brace is able to move the hip joint. The pelvis supporter supports a lower part of the pelvis, to directly transfer the weight of the upper half of the patient from the upper socket to the lower socket, thereby avoiding the femur and hip joint from receiving the weight. The brace has a simple structure, is low cost, is easily attached to and detached from a thigh, and allows a knee joint with the brace to move, to smoothly carry out rehabilitation.
