Nos. 4,771,768, 5,014,690, 5,611,773, 5,797,865 and 5,865,778.
In U.S. Pat. No. 4,771,768 a controlled motion ankle fracture walker is disclosed having a leg support interconnected to a foot support by a pair of pivotable rigid, lateral and medial uprights which allow for dorsi flexion or plantar flexion by the double action intersecting joints.
U.S. Pat. No. 5,014,690, claims an adjustable splint leg having a pair of spaced upper leg engagement struts pivotally connected to a pair of lower struts being spring bias with a cam surface defining a lower strut pivot point.
U.S. Pat. No. 5,611,773 is directed to an ankle pivot cap for the capture of a dorsi flexion and plantar flexion detent pins.
U.S. Pat. No. 5,797,865 has a lightweight ankle restraint made of plastic material with a pair of splint plates pivotally connected to struts of a foot engagement stirrup.
In U.S. Pat. No. 5,865,778 foot wear with integrated ankle support is disclosed wherein a resilient pivoting ankle brace has a malleable upper stirrup and a lower stirrup interconnected by an adjustment range of motion joint.
DeToro's own U.S. Pat. No. 5,908,398 is directed to an adjustable ankle and foot orthosis brace having an upper control leg support portion and a foot portion interconnected by an intermediate adjustable hinge assembly.
