Abstract
Abstract A thin, light-weight flexible orthotic device which has a therapeutic portion and a non-therapeutic portion. The therapeutic portion is shaped and contoured to engage a human foot and consists of: a distal forefoot supporting region; a proximal heel supporting region; and a medial arch supporting region. The non-therapeutic portion is a cut-out segment positioned laterally to the therapeutic portion. The orthopedic device includes posting material therein which supports a user's foot and control excessive midtarsal and subtalar pronation of the foot.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
328 words
A light-weight, low profile, anti-pronation orthopedic appliance for correctably supporting a human foot, comprising: (a) a therapeutic portion having a longitudinal axis extending lengthwise of the foot, said therapeutic portion including a distal forefoot-supporting section, a proximal heel-supporting section spaced longitudinally of the distal section, and a medial arch-supporting section located intermediate of and being of one-piece with the distal and proximal sections, (i) said distal section lying generally underneath the metatarsal head region at the medial side of the plantar aspect of the foot, and extending laterally of the longitudinal axis across the foot but terminating short of the lateral side of the plantar aspect of the foot, (ii) said proximal section lying generally underneath the inner heel region at the medial side of the plantar aspect of the foot, and extending laterally of the longitudinal axis across the foot but terminating short of the lateral side of the plantar aspect of the foot, (iii) said medial arch section lying generally underneath the arch region at the medial side of the plantar aspect of the foot, and extending laterally of the longitudinal axis across the foot but terminating short of the lateral side of the plantar aspect of the foot; (b) a non-therapeutic portion located laterally of the therapeutic portion and lying generally underneath and longitudinally along the lateral side of the plantar aspect of the foot, said non-therapeutic portion having a lower elevation along its length as compared to the correspondingly higher elevation of the therapeutic portion along its length, to thereby negatively support the lateral side of the plantar aspect of the foot; and (c) posting means operatively mounted on the therapeutic portion, for raising the elevation of the distal, proximal and medial arch sections at the medial side of the plantar aspect of the foot as compared to the respectively corresponding lower elevations at the lateral side of the plantar aspect of the foot, to thereby correctably support the foot in an anti-pronation manner.
Claim 2
Dependent Claim
328 words
A light-weight, low profile, anti-pronation orthopedic appliance for correctably supporting a human foot, comprising: (a) a therapeutic portion having a longitudinal axis extending lengthwise of the foot, said therapeutic portion including a distal forefoot-supporting section, a proximal heel-supporting section spaced longitudinally of the distal section, and a medial arch-supporting section located intermediate of and being of one-piece with the distal and proximal sections, (i) said distal section lying generally underneath the metatarsal head region at the medial side of the plantar aspect of the foot, and extending laterally of the longitudinal axis across the foot but terminating short of the lateral side of the plantar aspect of the foot, (ii) said proximal section lying generally underneath the inner heel region at the medial side of the plantar aspect of the foot, and extending laterally of the longitudinal axis across the foot but terminating short of the lateral side of the plantar aspect of the foot, (iii) said medial arch section lying generally underneath the arch region at the medial side of the plantar aspect of the foot, and extending laterally of the longitudinal axis across the foot but terminating short of the lateral side of the plantar aspect of the foot; (b) a non-therapeutic portion located laterally of the therapeutic portion and lying generally underneath and longitudinally along the lateral side of the plantar aspect of the foot, said non-therapeutic portion having a lower elevation along its length as compared to the correspondingly higher elevation of the therapeutic portion along its length, to thereby negatively support the lateral side of the plantar aspect of the foot; and (c) posting means operatively mounted on the therapeutic portion, for raising the elevation of the distal, proximal and medial arch sections at the medial side of the plantar aspect of the foot as compared to the respectively corresponding lower elevations at the lateral side of the plantar aspect of the foot, to thereby correctably support the foot in an anti-pronation manner.
Claim 3
Dependent Claim
26 words
The anti-pronation orthopedic appliance as defined in claim 1, wherein the distal section has a free distal edge lying generally underneath the sulcus of the foot.
Claim 4
Dependent Claim
18 words
The anti-pronation orthopedic appliance as defined in claim 1, wherein the distal section has a shallow concave cross-section.
Claim 5
Dependent Claim
42 words
The anti-pronation orthopedic appliance as defined in claim 1, wherein the distal section has an inner medial edge and an outer lateral edge; and wherein the elevation of the inner medial edge is higher than the elevation of the outer lateral edge.
Claim 6
Dependent Claim
54 words
The anti-pronation orthopedic appliance as defined in claim 1, wherein the medial arch section extends longitudinally from the distal section in an upwardly-rising continuous manner to a raised mid-crest region lying generally underneath the arch of the foot, and thereupon in a downwardly-falling continuous manner from the raised mid-crest region to the proximal section.
Claim 7
Dependent Claim
58 words
The anti-pronation orthopedic appliance as defined in claim 1, wherein the medial arch section has an inner edge and an outer lateral edge; and wherein the medial arch section has its highest elevation at said inner medial edge, and decreases continuously from the latter along the lateral direction to the outer lateral edge which has its lowest elevation.
Claim 8
Dependent Claim
57 words
The anti-pronation orthopedic appliance as defined in claim 1, wherein the proximal section has an inner medial edge and an outer lateral edge; and wherein the proximal section has its highest elevation at said inner medial edge, and decreases continuously from the latter along the lateral direction to the outer lateral edge which has its lowest elevation.
Claim 9
Dependent Claim
46 words
The anti-pronation orthopedic appliance as defined in claim 1, wherein the distal, medial arch and proximal sections have longitudinally-extending inner medial edges which are co-linear to define a common linear medial edge, and also have curved outer lateral edges to define a common arcuate lateral edge.
Claim 10
Dependent Claim
68 words
The anti-pronation orthopedic appliance as defined in claim 1, wherein the non-therapeutic portion includes a cut-out section lying laterally of the therapeutic portion, and a stabilizing section lying generally underneath the outer heel region at the lateral side of the plantar aspect of the foot; said stabilizing section being integrally connected to the proximal section by a backheel section lying generally underneath the backheel region of the foot.
Claim 11
Dependent Claim
51 words
The anti-pronation orthopedic appliance as defined in claim 9, wherein the proximal section has an inner medial edge, and wherein the stabilizing section has an outer lateral edge, and wherein the inner medial edge of the proximal section has a higher elevation than the outer lateral edge of the stabilizing section.
Claim 12
Dependent Claim
56 words
The anti-pronation orthopedic appliance as defined in claim 9, wherein the stabilizing section is the sole part of the orthopedic appliance at the lateral side of the plantar aspect of the foot, and extends longitudinally thereof from the heel region of the foot, but not past the region laterally of the arch region of the foot.
Claim 13
Dependent Claim
33 words
The anti-pronation orthopedic appliance as defined in claim 9, wherein the cut-out section extends longitudinally of the orthopedic appliance and into a cut-out space located between the proximal section and the stabilizing section.
