Abstract
Abstract The invention relates to a plate adapted to be secured to a bone surface in order to set broken bones, the plate having a modified I configuration in cross section for maximum strength characteristics and to enable the plate to be fitted against bones of varying surface contours, while the plate is of minimum thickness. The plate is provided with a plurality of countersunk apertures or slots to enable the plate to be secured to the bone by means of screws.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
177 words
A bone plate adapted to be secured to the exterior surface of a bone comprising: an elongated plate of modified I shape having a pair of generally parallel side flAnges, each of generally oval crosssection with one of the longer sides of the generally oval cross-section of each side flange facing the other side flange, the ends of said generally oval cross-sections being rounded on at least one side of the elongated plate to conform to bone surfaces of varying contours, and a central portion integral with said side flanges and extending between them, intersecting the side flanges at an intermediate point along the said facing long sides of their generally oval cross-sections, said central portion being of the same thickness across its width, from its intersection with one of said side flanges to its intersection with the other side flange, said thickness being less than the dimension of the side flanges taken in the longer direction of the said generally oval cross-section and apertures in said central portion to receive screws for securing to the bone.
Claim 2
Dependent Claim
177 words
A bone plate adapted to be secured to the exterior surface of a bone comprising: an elongated plate of modified I shape having a pair of generally parallel side flAnges, each of generally oval crosssection with one of the longer sides of the generally oval cross-section of each side flange facing the other side flange, the ends of said generally oval cross-sections being rounded on at least one side of the elongated plate to conform to bone surfaces of varying contours, and a central portion integral with said side flanges and extending between them, intersecting the side flanges at an intermediate point along the said facing long sides of their generally oval cross-sections, said central portion being of the same thickness across its width, from its intersection with one of said side flanges to its intersection with the other side flange, said thickness being less than the dimension of the side flanges taken in the longer direction of the said generally oval cross-section and apertures in said central portion to receive screws for securing to the bone.
Claim 3
Dependent Claim
39 words
A bone plate according to claim 1, wherein said apertures are countersunk on one surface of the central portion and the outer side faces of the side flanges are curved inwardly in a direction towards the countersunk apertured surface.
Claim 4
Dependent Claim
18 words
A bone plate according to claim 2, wherein said apertures comprise slots extending longitudinally in said central portion.
Claim 5
Dependent Claim
64 words
A bone plate according to claim 1, the surfaces of said central portion being curved in a direction transverse to the longitudinal direction of the plate, both surfaces being curved in the same direction as each other so as to extend substantially parallel and in space relation with respect to the surface of the bone to which the plate is adapted to be secured.
Claim 6
Dependent Claim
63 words
A bone plate according to claim 4, wherein said apertures comprise slots extending along the longitudinal axis of said central portion and including washers having countersunk apertures therein, said washers being located on one side of said central portion and having a thickness substantially equal to the distance which said flanged sides extend perpendicularly away from said one surface of the central portion.
Claim 7
Dependent Claim
62 words
A bone plate according to claim 1, having a total width from the outside of one side flange to the outside of the other flange within the range of 0.375 to 0.750 inches, said central portion having a thickness within the range of 0.093 to 0.186 inches, and the side flanges having a thickness within the range of 0.167 to 0.333 inches.
