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.
A device for restoring the function of the lower extremities comprising: a mechanism for restoring the function of the ankle joint comprising: two pairs of half-rings, one of said pairs including 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 at their ends; the other of said pairs including 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; articulated distraction members mounted on the ends of said axial and rotatable half-rings and adapted to join together said pairs of half-rings; a mechanism for correcting deformities of the foot, comprising: brackets rigidly secured to the ends of said axial half-ring; spindles fastened to said brackets; L-shaped connecting rods rotatably mounted on said spindles; ties to couple respective ones of the arms of said L-shaped connecting rods with the ends of the locking half-ring, which is fastened to the metatarsal bones of the foot; a spoke that is driven through the heel bone and is fastened to corresponding ones of the arms of said L-shaped connecting rods.
