Abstract
Abstract An orthopedic appliance for bracing the human knee and restraining the same against normal knee bending movement or genuflection, or other knee movement, such as lateral movement. The appliance wraps around the leg and is provided with an opening through which the patella may extend, and opposite such opening is a resilient pad of tapered form engageable with the popliteal area of the knee. Rearwardly of the pad are rigid longitudinally extending bracing elements, and additional parallel elements are provided adjacent the patella opening to prevent lateral movement.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
145 words
An orthopedic appliance for immobilizing a limb joint comprising: a generally pliant base sheet deformable from a flat inoperable position to a generally tubular configuration having opposed axial ends to embrace the limb; means releasably securing said sheet in said tubular configuration about the joint of the limb; a rigid planar stifferner extending longitudinally of and secured to said sheet medially of the oPposed side edges thereof to be positioned at the rear of the joint; resilient pad means overlying at least a medial portion of and interiorly of said stiffener, and being secured to said sheet; said pad means increasing in thickness from its opposed axial ends to its longitudinal central portion for conforming to and filling the natural body cavity between said stiffener and the rearward portion of the limb joint; and said stiffener and pad means preventing bending of the limb joint.
Claim 2
Dependent Claim
145 words
An orthopedic appliance for immobilizing a limb joint comprising: a generally pliant base sheet deformable from a flat inoperable position to a generally tubular configuration having opposed axial ends to embrace the limb; means releasably securing said sheet in said tubular configuration about the joint of the limb; a rigid planar stifferner extending longitudinally of and secured to said sheet medially of the oPposed side edges thereof to be positioned at the rear of the joint; resilient pad means overlying at least a medial portion of and interiorly of said stiffener, and being secured to said sheet; said pad means increasing in thickness from its opposed axial ends to its longitudinal central portion for conforming to and filling the natural body cavity between said stiffener and the rearward portion of the limb joint; and said stiffener and pad means preventing bending of the limb joint.
Claim 3
Dependent Claim
20 words
An appliance as set forth in claim 1 in which said pad has a flat triangular configuration in longitudinal cross-section.
Claim 4
Dependent Claim
44 words
An appliance as set forth in claim 2 in which said pad has opposed side walls spaced inwardly from said base sheet side edges, and said end portions of said pad are spaced inwardly of the longitudinally spaced end portions of said base sheet.
Claim 5
Dependent Claim
36 words
An appliance as set forth in claim 1 in which a plurality of said stiffeners are provided each extending between the opposite end edges of said sheet and all having their central portions subjacent said pad.
Claim 6
Dependent Claim
32 words
An appliance as set forth in claim 1 in which a second rigid planar stiffener is secured to said sheet intermediate said pad and each of said side edges of said sheet.
Claim 7
Dependent Claim
22 words
An appliance as set forth in claim 5 in which a strip of resilient pad material overlies each of said second stiffeners.
Claim 8
Dependent Claim
18 words
An appliance as set forth in claim 1 in which said pad is of generally rectangular plan configuration.
Claim 9
Dependent Claim
55 words
An appliance as set forth in claim 1 in which said side edges are provided with inwardly directed recesses intermediate the longitudinally spaced opposed axial ends of said base sheet, said recesses cooperating to define an opening receiving the front projection of the limb joing when said base sheet is deformed into said tubular configuration.
Claim 10
Dependent Claim
98 words
An orthopedic appliance comprising a generally pliant base sheet deformable from a flat inoperable position to a generally tubular configuration to embrace a limb, means releasably securing said sheet in said tubular configuration, a rigid planar stiffener extending longitudinally of and secured to said sheet medially of the opposed side edges thereof, a resilient pad of material overlying at least a medial portion of said stiffener and secured to said sheet, said pad having end portions of a lesser thickness than the longitudinal central portion thereof and said pad having a flat triangular configuration in longitudinal cross section.
Claim 11
Dependent Claim
98 words
An orthopedic appliance comprising a generally pliant base sheet deformable from a flat inoperable position to a generally tubular configuration to embrace a limb, means releasably securing said sheet in said tubular configuration, a rigid planar stiffener extending longitudinally of and secured to said sheet medially of the opposed side edges thereof, a resilient pad of material overlying at least a medial portion of said stiffener and secured to said sheet, said pad having end portions of a lesser thickness than the longitudinal central portion thereof and said pad having a flat triangular configuration in longitudinal cross section.
Claim 12
Dependent Claim
44 words
An appliance as set forth in claim 9, in which said pad has opposed side walls spaced inwardly from said base sheet side edges, and said end portions of said pad are spaced inwardly of the longitudinally spaced end portions of said base sheet.
