Abstract
A corrective device for the positioning of a foot is an apparatus used to treat foot drop. The apparatus includes a spring, a bone anchor assembly, and a tendon anchor assembly. The spring is used to prevent the foot from drooping downward. The spring includes a coil, a first spring coupler, and a second spring coupler. The first spring coupler is used to connect the coil to the bone anchor assembly. The bone anchor assembly anchors the apparatus to a human tibia. The second spring coupler is used to connect the coil to the tendon anchor assembly. The tendon anchor assembly is used to anchor the apparatus to one or more tendons in the foot. Because the coil is anchored above and below the ankle, rotations about the ankle may be limited by the coil.
