A device and method are disclosed for the fusion of joints (particularly finger joints or toe joints) in a bent (or angled) position. In certain embodiments, a device for the fusion of joints preferably allows for one or more of various angled positions, and the particular angle may differ for different joints. The device is preferably a bendable implant device for fusing together bones or a joint.

Devices and methods are disclosed for the fusion of joints (particularly finger joints or toe joints) in a bent (or angled) position. In certain embodiments, the device is pre-bent and inserted into the joint in its pre-bent configuration. Alternatively, the device may be configured to have a first position wherein it is bent and a second position wherein it is straight. In that case, the device is preferably straightened by inserting a K-wire through a cannula in the device, and the device can be inserted into the joint in its straight position. Once inserted, the device is permitted to move to its bent position, which moves the joint to a bent position. In one embodiment the device moves to its bent position when the K-wire is removed.

Embodiments of the present invention are generally related to the manipulation of a joint to provide therapy. More specifically, some embodiments of the present invention use inflatable members and a three point bending concept to cause flexion in a toe joint for the purpose of increasing the range of motion of the toe joint. In one embodiment, a user's foot is placed in a frame with at least one toe atop a toe bar. An inflatable member is positioned atop the user's foot and held in position with a strap attached relative to the frame. As the inflatable member is inflated, the strap increases in tension urging the toe toward the toe bar and causing actuation of the joint at the base of the toe.

The invention relates to a simulated sole with toe joint, which can detect the vertical pressure of sole, with simple structure, wherein it comprises front sole, back sole, sensitive detector, rotation axle connecting front and back soles, and relative transmitters. Each sensitive detector comprises one suspension beam, two stress plates, two bolts, one adjustable nut, one muffle, one guide block, one anti-impact polyester rubber block. The rotation axle and transmitters comprise rotation axle, bearing, bearing base, axial base, motor base, gear, synchronous tooth band, bolt, direct-current motor, speed reducer, and coder. The invention can simulate the toe motion of human, with small volume, light weight, and compact structure.

A walking movement device is provided for producing a walking movement of a human being with two controlled foot guiding units, each having a foot plate for placing a foot thereon. The foot plates are alternately movable forward and backwards in opposite directions to stimulate the walking movement. The foot plates are coupled with at least one drive unit, via which drive unit the walking movement of the foot plates can be produced, and have a suspension unit for easing the weight on the human being. The foot plates each have a front and a rear partial area with the at least one drive unit being configured to move the rear partial area out of the common plane with respect to the front partial area and back again during the walking movement of the foot plates, in order to enable bending of the midfoot toe joint during the movement process.

The invention relates to a dynamic below-knee artificial limb containing flexible dynamic ankle joints and toe joints, which is characterized by comprising an ankle joint moving mechanism and a toe joint moving mechanism, wherein the ankle joint moving mechanism comprises a back sole, an ankle joint supporting frame, shank baffle plates and an ankle joint motor; the ankle joint supporting frame is fixed at the upper part of the back sole, and the upper end of the ankle joint supporting frame is articulated with an ankle joint shaft connecting frame connected between two shank baffle plates; the ankle joint motor is fixedly connected between the two shank baffle plates, the output end of the ankle joint motor is fixedly connected with one end of an ankle joint screw through a shaft coupling, and the other end of the screw is connected with the back sole through an ankle joint spring mechanism; the toe joint moving mechanism comprises a front sole and a toe joint motor, wherein the front sole is articulated with the back sole, and the toe joint motor is fixedly connected with the back sole; an output shaft of the toe joint motor is fixedly connected with one end of a toe joint screwthrough a shaft coupling, and the other end of the screw is articulated with a toe joint screw fixing frame; and the toe joint screw is connected with the front sole through a toe joint spring mechanism. The dynamic below-knee artificial limb can be widely applied to the researches on the flexible dynamic joints of artificial limbs and serves the handicapped.

An artificial toe joint utilizes a ball in socket joint structure and arms or side walls which are exterior to the bone. The resulting joint provides improved strength and durability, and may be used to repair joints which are not suitable for installation of a prior art artificial joint.
