Ankle/foot orthosis
First Claim
1. A foot and ankle orthosis which is adapted for use by a patient in both resting and walking modes, the orthosis comprising:
- a generally L-shaped support member which has a leg portion positioned behind the patient'"'"'s lower leg, a heel portion positioned behind the patient'"'"'s heel and Achilles'"'"' tendon area, and a foot portion positioned substantially entirely against the sole of the patient'"'"'s foot when the orthosis is in the normal, operative use position, the foot portion having an upper surface and a lower surface and the heel portion connecting the leg portion and the foot portion;
a walking sole plate which is releasably connectable to the generally L-shaped support member, to thereby permit optional use by the patient of the walking sole plate in combination with the generally L-shaped support member for facilitating ambulation by the patient;
a manually operable locking mechanism attached to the lower surface of the foot portion of the generally L-shaped support member, to thereby permit rapid, selectively releasable connection of the walking sole plate to the generally L-shaped support member, wherein the manually operable locking mechanism attached to the bottom surface of the foot portion of the L-shaped support member includes a first base plate and a second base plate, the first base plate and the second base plate being fixed to the lower surface of the semi-rigid foot bed and positioned substantially parallel to each other and transversely with respect to the longitudinal axis of the semi-rigid foot bed, the first base plate being disposed forwardly of the second base plate, a connecting plate fixed to the second base plate and extending outwardly and rearwardly therefrom, thereby defining a space between the lower surface of the semi-rigid foot bed and an upper surface of the connecting plate to receive and retain a portion of the semi-rigid foot bed of the walking sole plate, and a key nut rotatably connected to the first base plate and extending outwardly therefrom to further retain the semi-rigid foot bed in position for selective operative use of the walking sole plate and to permit ready, manual release of the walking sole plate from an operative position thereof; and
means for connecting the orthosis to the patient'"'"'s foot and leg.

Abstract
A foot and ankle orthosis is adapted for use by a patient in both resting and walking modes. The orthosis includes a generally L-shaped support member which has a leg portion positioned behind the patient'"'"'s lower leg, a heel portion positioned behind the patient'"'"'s heel and Achilles'"'"' tendon area, and a foot portion positioned substantially entirely against the sole of the patient'"'"'s foot, when in normal operative use position. The foot portion has an upper surface and a lower surface and the heel portion connects the leg portion and the foot portion. A walking sole plate is releasably connectable to the generally L-shaped support member, to thereby permit optional use by the patient of the walking sole plate in combination with the generally L-shaped support member for facilitating ambulation by the patient. A manually operable locking mechanism is attached to the lower surface of the foot portion of the generally L-shaped support member, to thereby permit rapid, selectively; releasable connection of the walking sole plate to the generally L-shaped support member.

1. A foot and ankle orthosis which is adapted for use by a patient in both resting and walking modes, the orthosis comprising:
-
a generally L-shaped support member which has a leg portion positioned behind the patient'"'"'s lower leg, a heel portion positioned behind the patient'"'"'s heel and Achilles'"'"' tendon area, and a foot portion positioned substantially entirely against the sole of the patient'"'"'s foot when the orthosis is in the normal, operative use position, the foot portion having an upper surface and a lower surface and the heel portion connecting the leg portion and the foot portion; a walking sole plate which is releasably connectable to the generally L-shaped support member, to thereby permit optional use by the patient of the walking sole plate in combination with the generally L-shaped support member for facilitating ambulation by the patient; a manually operable locking mechanism attached to the lower surface of the foot portion of the generally L-shaped support member, to thereby permit rapid, selectively releasable connection of the walking sole plate to the generally L-shaped support member, wherein the manually operable locking mechanism attached to the bottom surface of the foot portion of the L-shaped support member includes a first base plate and a second base plate, the first base plate and the second base plate being fixed to the lower surface of the semi-rigid foot bed and positioned substantially parallel to each other and transversely with respect to the longitudinal axis of the semi-rigid foot bed, the first base plate being disposed forwardly of the second base plate, a connecting plate fixed to the second base plate and extending outwardly and rearwardly therefrom, thereby defining a space between the lower surface of the semi-rigid foot bed and an upper surface of the connecting plate to receive and retain a portion of the semi-rigid foot bed of the walking sole plate, and a key nut rotatably connected to the first base plate and extending outwardly therefrom to further retain the semi-rigid foot bed in position for selective operative use of the walking sole plate and to permit ready, manual release of the walking sole plate from an operative position thereof; and means for connecting the orthosis to the patient'"'"'s foot and leg. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. The combination of a foot and ankle orthosis, and a cover for the foot and ankle orthosis to hold the orthosis in place on a patient'"'"'s foot and lower leg and to relieve pressure from the material of the orthosis against the tissue of the patient'"'"'s foot and lower leg,
wherein the orthosis comprises a generally L-shaped support member which, when the orthosis is in normal use position, has a leg portion positioned behind the patient'"'"'s lower leg, a heel portion positioned behind the patient'"'"'s heel and Achilles'"'"' tendon area, and a foot portion positioned substantially entirely against the sole of the patient'"'"'s foot, the foot portion having an upper surface and a lower surface; -
a walking sole plate which is releasably connectable to the generally L-shaped support member, to thereby permit optional use by the patient of the walking sole plate in combination with the generally L-shaped support member for facilitating ambulation by the patient; a manually operable locking mechanism attached to the lower surface of the foot portion of the generally L-shaped support member, to thereby permit rapid, selectively;
releasable connection of the walking sole plate to the generally L-shaped support member, wherein the manually operable locking mechanism attached to the bottom surface of the foot portion of the L-shaped support member includes a first base plate and a second base plate, the first base plate and the second base plate being fixed to the lower surface of the semi-rigid foot bed and positioned substantially parallel to each other and transversely with respect to the longitudinal axis of the semi-rigid foot bed, the first base plate being disposed forwardly of the second base plate, a connecting plate fixed to the second base plate and extending outwardly and rearwardly therefrom, thereby defining a space between the lower surface of the semi-rigid foot bed and an upper surface of the connecting plate to receive and retain a portion of the semi-rigid foot bed of the walking sole plate, and a key nut rotatably connected to the first base plate and extending outwardly therefrom to further retain the semi-rigid foot bed in position for selective operative use of the walking sole plate and to permit ready, manual release of the walking sole plate from an operative position thereof; andfurther wherein the cover comprises a plurality of flexible material sections connected together as a single unit shaped to cover substantially all of the patient'"'"'s foot, but leaving the toes free and unencumbered.
