Claim 8

The bone plate in accordance with claim 5 wherein said bone plate is of various polygonal configurations.

Claim 9

The bone plate in accordance with claim 3 wherein said positioning member comprises a different material of construction than the remainder of said bone plate.

Claim 10

The bone plate in accordance with claim 7 wherein said positioning member is affixed by malleable material.

Claim 11

The bone plate in accordance with claim 7 wherein said positioning member is removable and plastic, and is molded in removable relationship to said bone plate.

Claim 12

The bone plate in accordance with claim 6 wherein said plate is L-shaped and said removable positioning member is located at the foot of the L.

Claim 13

A bone plate for use in bone fractures comprising the combination of: a generally planar plate of inert material having at least two spaced openings adapted to receive fasteners for securing said plate, said plate having a generally flat surface adapted to be placed adjacent to the bone to which said plate is to be affixed and the opposite surface thereof being generally flat with rounded edges, said plate having a slender, malleable, prong-like positioning member which is of sufficient size to manipulate and ready said bone plate for fixation, said positioning member being adapted to be bent from a first position wherein said positioning member projects away from said bone plate to a second position wherein said positioning member is aligned closely adjacent said bone plate, wherein said positioning member is positionable with respect to said plate and after fixation of said bone plate is intended to be positioned in said second position.

Claim 14

A bone plate for use in bone fractures comprising the combination of: a generally planar plate of inert material having at least two spaced openings adapted to receive fasteners for securing said plate, said plate having a generally flat surface adapted to be placed adjacent to the bone to which said plate is to be affixed and the opposite surface thereof being generally flat with rounded edges, said plate having a slender, malleable, prong-like positioning member which is of sufficient size to manipulate and ready said bone plate for fixation, said positioning member being adapted to be bent from a first position wherein said positioning member projects away from said bone plate to a second position wherein said positioning member is aligned closely adjacent said bone plate, wherein said positioning member is positionable with respect to said plate and after fixation of said bone plate is intended to be positioned in said second position.

Claim 15

The bone plate in accordance with claim 11 wherein said positioning member comprises a tubular end portion having a recess therein to receive a congruently shaped end of a surgical tool used to manipulate said bone plate.

Claim 16

A bone plate for use in bone fractures or osteotomies comprising: a plurality of substantially planar annular portions joined by strip segments, with no more than two such strip segments adjoining any annular portion, said annular portions and strip segments having a generally D-shaped cross section, so that a lower surface of said bone plate is flat and an upper surface of said bone plate is generally flat with rounded edges; and a positioning tab member joined to one of said annular portions, said tab member being generally thin and flat with a narrowed down neck part adjacent said annular portion adapted for easy separation of said tab member from said annular portion; wherein said tab member is useful in manipulating said bone plate during fixation and may be easily removed after said bone plate is affixed to bone with the insertion of fastening means through said annular portions.

Claim 17

A bone plate for use in bone fractures or osteotomies comprising: a plurality of substantially planar annular portions joined by strip segments, with no more than two such strip segments adjoining any annular portion, said annular portions and strip segments having a generally D-shaped cross section, so that a lower surface of said bone plate is flat and an upper surface of said bone plate is generally flat with rounded edges; and a positioning tab member joined to one of said annular portions, said tab member being generally thin and flat with a narrowed down neck part adjacent said annular portion adapted for easy separation of said tab member from said annular portion; wherein said tab member is useful in manipulating said bone plate during fixation and may be easily removed after said bone plate is affixed to bone with the insertion of fastening means through said annular portions.

Claim 18

The bone plate of claim 13 wherein each of said plurality of annular portions has a central hole surrounded on said upper surface of said plate by an annular countersunk region adapted to receive fastening means having a complementarily shaped surface abutting said countersunk region.

Claim 19

Claim 22

The bone plate of claim 17 wherein said positioning tab member comprises a plastic material attached in such a manner that said tab member is easily separable from said annular portion.

Claim 23

The bone plate of claim 13 wherein said positioning tab member has a narrow width and a constant cross section and is adapted to have its orientation with respect to said annular portion easily changed by finger pressure or the use of a handling tool.

Claim 24

The bone plate of claim 19 wherein said positioning tab member comprises a malleable material and is easily separable from said annular portion to which said tab member is joined, by fatigue in bending said tab member along a line adjacent said annular member.
