1. A modular ankle foot orthotic system for securing to a patient's leg below the knee comprising a) a composite strut approximating the contour and length of the rear of the calf of the lower leg of the patient, b) a footplate formed of a composite material shaped to substantially conform to a lower surface, sides and heel of the patient's foot, said footplate including a Y-shaped stirrup formed from a structural material molded therein, the open end of the Y-shaped stirrup angled downward from an ankle area of the footplate to an arch of the footplate, the footplate being secured to a lower end of the strut, c) an upper tibial cuff sized to encircle the upper portion of the lower leg of the patient below the knee in a snug manner, the upper tibial cuff being secured to an upper end of the strut, d) a lower tibial cuff shaped to conform to the rear and sides of the patient's mid-calf area, the lower tibial cuff being secured to a central portion of the strut in a moveable manner, and e) attachment components and wedge plates or discs which taper to a thinner end for securing the footplate and upper and lower cuffs to the strut, the wedge plates providing angulation to the footplate and cuffs once secured to the strut, said orthotic system assembled by sandwiching one or more wedge plates between the strut on a first side and each of the positioned Y-shaped stirrup, upper cuff and lower cuff on a second side of the wedges.
