Abstract
Abstract A three dimensional implantable bone brace having a pair of elongated integral flanges connected along one lengthwise edge of each and disposed substantially at right angles to each other. One of said flanges has a plurality of spaced transverse slots which permit bending of the other flange in a direction parallel with said one flange. The other flange has a plurality of openings through which screw means can be inserted for fixing said brace against the lateral surface of a mandible, for example, when said one flange extends into a groove cut into said surface.

A three-dimensional bone brace for securement to an injured mandible having a groove cut in the lateral surface thereof, comprising:
Claim 2
Dependent Claim
20 words
A three-dimensional bone brace for securement to an injured mandible having a groove cut in the lateral surface thereof, comprising:
Claim 3
Dependent Claim
207 words
an elongated L-shaped metallic angle member having first and second substantially rectangular flanges disposed substantially at right angles to each other, each of said flanges having a free edge extending longitudinally of said angle member, the free edges of said flanges being substantially parallel; means for permitting said first flange to be bent into a substantially arcuate and nonplanar shape conforming to the lateral surface of the mandible when a material bending force is applied to said angle member, said means comprising a plurality of substantially uniformly spaced slots in said second flange, each slot extending transversely of said second flange from a point substantially adjacent the inner surface of the first flange through the free edge of said second flange, said slots permitting bending of said second flange within the plane thereof; and a plurality of openings extending through said first flange for reception of screw means whereby said first flange can be fixedly secured snugly against the lateral surface when the second flange is disposed within a said groove in said mandible, said openings being spaced inwardly from the free edge of said first flange, and the free edge of said first flange being substantially straight and continuous throughout the length of said angle member.
Claim 4
Dependent Claim
207 words
an elongated L-shaped metallic angle member having first and second substantially rectangular flanges disposed substantially at right angles to each other, each of said flanges having a free edge extending longitudinally of said angle member, the free edges of said flanges being substantially parallel; means for permitting said first flange to be bent into a substantially arcuate and nonplanar shape conforming to the lateral surface of the mandible when a material bending force is applied to said angle member, said means comprising a plurality of substantially uniformly spaced slots in said second flange, each slot extending transversely of said second flange from a point substantially adjacent the inner surface of the first flange through the free edge of said second flange, said slots permitting bending of said second flange within the plane thereof; and a plurality of openings extending through said first flange for reception of screw means whereby said first flange can be fixedly secured snugly against the lateral surface when the second flange is disposed within a said groove in said mandible, said openings being spaced inwardly from the free edge of said first flange, and the free edge of said first flange being substantially straight and continuous throughout the length of said angle member.
Claim 5
Dependent Claim
64 words
A bone brace according to claim 1 wherein each of said slots is elongated in a direction extending transversely across said second flange, each of said slots being of narrow and substantially uniform width throughout the length thereof, whereby said slots divide said second flange into a plurality of substantially rectangular separated portions which project transversely from said first flange in a cantilevered manner.
Claim 6
Dependent Claim
47 words
A bone brace according to claim 2, wherein adjacent ones of said rectangular portions have opposed edges defining one of said slots therebetween, said opposed edges being substantially parallel and spaced apart by a distance in the range of between about 0.050 and 0.090 of an inch.
