ABSTRACT:
A device for below knee orthosis is in the form of brace having a foot plate provided with an upper surface adapted to be situated beneath a foot. Below this upper surface the foot plate is formed just to the rear of the arch region, but forwardly of the rear end of the heel region, with a transverse slot extending inwardly from at least one side of the foot plate, this slot being adapted to receive the lower horizontal leg of a substantially L-shaped lower bar member which has an upright leg extending upwardly from the lower horizontal leg thereof. To the top end of the upright leg is pivotally connected an upper upright bar portion for a given degree of turning movement with respect to the upright leg of the lower bar portion, and this upper bar portion carries at its upper end region a strap which is adapted to encircle a leg. An ankle strap is operatively connected with the foot plate to the rear of the slot thereof for securing the structure to the ankle, while the upper strap secures the upright bar structure to the leg. All of the above structure forms a separate unit capable of being removably received in a shoe, so that different shoes may be used with the same unit.
