Abstract
Abstract A thigh brace for maintaining broken bone segments in the proper healing orientation by protecting and reinforcing the surfaces of the upper leg between the hip and knee is disclosed. The thigh brace includes an elongate generally U-shaped interior member which extends around the laterally interior surface of the upper leg and which is flexible. The thigh brace also includes an elongate, generally C-shaped exterior member which extends around the laterally exterior surface of the upper leg and which is similarly flexible. The longitudinal side edges of the exterior member are disposed in overlapping relationship with the longitudinal side edges of the interior member so that the exterior member and interior member encase the upper leg and provide increased lateral support to hold the broken bone segments in the proper healing orientation and protect against valgus or varus movement of the broken bone segments. The thigh brace also includes a keeper for holding the members in mating relationship and a retaining device for retaining the members in the desired location on the upper leg. Preferably, the retaining device is a tibia brace secured to the lower leg and connected to the thigh brace. Conveniently, the connection is a pair of pivoted struts having two axes pivots. The struts are attached to the thigh brace and recesses provided in the members.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
276 words
A thigh brace for maintaining broken bone segments in the proper healing orientation by protecting and reinforcing the surfaces of the upper leg between the hip and knee, said brace comprising: an elongage, generally U-shaped interior member having a base and sidewalls extending around the laterally interior surface of the upper leg, said interior member being made of semi-rigid material with said sidewalls capable of being flexed; an elongate, generally C-shaped exterior member having a base and sidewalls extending around the laterally exterior surface of the upper leg, said exterior member being made of semi-rigid material with said sidewalls capable of being flexed, the longitudinal side edges of said exterior member being disposed in overlapping relationship with the longitudinal side edges of said interior member whereby said interior and exterior members encase the upper leg with the inner surfaces of said interior and exterior members in contact with the surface of the upper leg; a keeper means for stabilizing said members in mating relation to one another; a retaining means for retaining said members in the desired location on the upper leg, said retaining means including a tibia brace which is secured about the lower leg and a connecting means for connecting said tibia brace to said thigh brace such that said tibia brace and said thigh brace move as a unit along the longitudinal length of the leg, said connecting means including a pair of pivoted struts attached to respective lateral sides of said thigh brace and said tibia brace; the pivot of each of said pivoted struts comprising a two-axis pivot to accomodate the changing center axis of the knee as the knee flexes.
Claim 2
Dependent Claim
276 words
A thigh brace for maintaining broken bone segments in the proper healing orientation by protecting and reinforcing the surfaces of the upper leg between the hip and knee, said brace comprising: an elongage, generally U-shaped interior member having a base and sidewalls extending around the laterally interior surface of the upper leg, said interior member being made of semi-rigid material with said sidewalls capable of being flexed; an elongate, generally C-shaped exterior member having a base and sidewalls extending around the laterally exterior surface of the upper leg, said exterior member being made of semi-rigid material with said sidewalls capable of being flexed, the longitudinal side edges of said exterior member being disposed in overlapping relationship with the longitudinal side edges of said interior member whereby said interior and exterior members encase the upper leg with the inner surfaces of said interior and exterior members in contact with the surface of the upper leg; a keeper means for stabilizing said members in mating relation to one another; a retaining means for retaining said members in the desired location on the upper leg, said retaining means including a tibia brace which is secured about the lower leg and a connecting means for connecting said tibia brace to said thigh brace such that said tibia brace and said thigh brace move as a unit along the longitudinal length of the leg, said connecting means including a pair of pivoted struts attached to respective lateral sides of said thigh brace and said tibia brace; the pivot of each of said pivoted struts comprising a two-axis pivot to accomodate the changing center axis of the knee as the knee flexes.
Claim 3
Dependent Claim
112 words
A thigh brace as claimed in claim 1 wherein said tibia brace includes an elongate, generally U-shaped posterior member having a base and sidewalls extending around the posterior surface of the lower leg and an elongate, generally C-shaped anterior member having a base and sidewalls extending around the anterior surface of the lower leg, the longitudinal side edges of said anterior member being disposed in overlapping relationship with the longitudinal side edges of the posterior member whereby said anterior and posterior members encase the lower leg with the inner surfaces of said anterior and posterior members being in contact with the surface of the lower leg and held relatively immovably in place.
Claim 4
Dependent Claim
22 words
A thigh brace as claimed in claim 2 wherein said tibia brace further includes a heel rest attached to said posterior member.
Claim 5
Dependent Claim
19 words
A thigh brace as claimed in claim 1 wherein said pivoted struts are made of a rigid plastics material.
Claim 6
Dependent Claim
62 words
A thigh brace as claimed in claim 4 wherein said pivoted struts are attached to the inside surface of respective said interior and exterior members, said interior and exterior members having a recess in said bases on which said struts are located whereby the relatively smooth U-shape and C-shape, respectively, of the inside surfaces of said interior and exterior members are maintained.
Claim 7
Dependent Claim
24 words
A thigh brace as claimed in claim 1 wherein said keeper means includes fastener means for releasably fastening said interior and exterior members together.
Claim 8
Dependent Claim
26 words
A thigh brace as claimed in claim 6 wherein said fastener means includes straps extending around a substantial portion of the periphery of said thigh brace.
Claim 9
Dependent Claim
28 words
A thigh brace as claimed in claim 1 wherein said members are tapered along the length of said members to conform with the tapering of the upper leg.
