Abstract
Abstract A plastic orthotic therapeutic device which applied correcting pressure for varus or foot inversion and equinus or foot drop. This combination is prevalent in a condition known as spastic equinovarus which occurs with alarming frequency in post-stroke and brain injured patients. Equinus is controlled by a three pressure point system consisting of a foot plate, a broad proximal posterior section and the wearer's shoe. Varus is controlled by a three point pressure point system consisting of an appropriately relieved and padded malleolar area, a high medial wall, an extended projection proximal to medial malleolus, and an extended trim line over the first tarsal bone of the wearer. This orthosis is made of lightweight, hygienic polypropylene and may be worn inside the patient's shoe. It is easily donned and doffed using only one hand.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
190 words
A plastic orthotic therapeutic device comprising in combination greave or leg section, a plantar or foot section, said greave or leg section and said plantar or foot section being integral and rigidly formed of unitary construction, means for providing forces to correct the deforming components of equinus or foot drop, simultaneous means for providing forces to correct the deforming components of varus or foot inversion, means for providing for comfort to a wearer when said plastic orthotic device is worn and means for allowing the wearer of said orthotic device to easily don and doff said device, wherein said means for providing forces to correct the deforming components of equinus or foot drop consist of a three point pressure system including a foot plate, a broad proximal posterior section, and the shoe of the wearer, and wherein said means for providing forces to correct the deforming components of varus or foot inversion consist of a three point pressure system including an appropriately relieved malleolar area, a high medial wall, an extended projection proximal to the medial malleolus, and an extended trim line over the first tarsal bone of said wearer.
Claim 2
Dependent Claim
190 words
A plastic orthotic therapeutic device comprising in combination greave or leg section, a plantar or foot section, said greave or leg section and said plantar or foot section being integral and rigidly formed of unitary construction, means for providing forces to correct the deforming components of equinus or foot drop, simultaneous means for providing forces to correct the deforming components of varus or foot inversion, means for providing for comfort to a wearer when said plastic orthotic device is worn and means for allowing the wearer of said orthotic device to easily don and doff said device, wherein said means for providing forces to correct the deforming components of equinus or foot drop consist of a three point pressure system including a foot plate, a broad proximal posterior section, and the shoe of the wearer, and wherein said means for providing forces to correct the deforming components of varus or foot inversion consist of a three point pressure system including an appropriately relieved malleolar area, a high medial wall, an extended projection proximal to the medial malleolus, and an extended trim line over the first tarsal bone of said wearer.
Claim 3
Dependent Claim
40 words
A plastic orthotic therapeutic device, as recited in claim 1, wherein said greave or leg section is molded out of a thermally moldable yet rigid material in such manner as to fit the leg and calf contour of said wearer.
Claim 4
Dependent Claim
37 words
A plastic orthotic therapeutic device, as recited in claim 1, wherein said plantar or foot section is molded out of a thermally moldable yet rigid material in such manner as to fit the foot of said wearer.
Claim 5
Dependent Claim

A plastic orthotic therapeutic device, as recited in claim 1, wherein said means for providing for comfort to said wearer when said plastic orthotic therapeutic device is worn consists of padding a relieved malleolar area and padding all attachment hood and loop pile fastener straps.
Claim 6
Dependent Claim
57 words
A plastic orthotic therapeutic device, as recited in claim 1, wherein said means for allowing the wearer of said orthotic device to easily don and doff said device consists of at least one hook and loop pile fastener strap and means for securing said strap so that orthotic device remains fixedly in place when said wearer walks.
Claim 7
Dependent Claim
44 words
A plastic orthotic therapeutic device as recited in claim 5, wherein said means for securing said strap consists of riveting said strap to an appropriate place on said orthotic device and providing a matching buckle which is mounted to an opposing appropriate connection point.
