ABSTRACT:
The device of the invention comprises a mechanism for restoring the function of the ankle joint and a mechanism for correcting deformities of the foot. The mechanism for restoring the function of the ankle joint includes two pairs of half-rings, one of said pairs comprising an axial half-ring, which is fastened to the axle of rotation of the ankle joint, and a locking half-ring, which is fastened to the metatarsal bones of the foot, said half-rings being rigidly secured to each other. The other of said pairs includes a rotatable half-ring, which is fastened to the distal portion of the shin bone, and a locking half-ring, which is fastened to the middle portion of the shin bone, said half-rings being rigidly secured to each other. The mechanism for correcting deformities of the foot comprises brackets rigidly secured to the ends of the axial half-ring. The brackets carry spindles rotatably mounting L-shaped connecting rods. Corresponding ones of the arms of the L-shaped connecting rods are coupled with the ends of the locking half-ring fastened to the metatarsal bones of the foot, while respective ones of the arms of the connecting rods are coupled with the heel bone of the foot.
