Abstract

A member of a modular bone plate is provided, the member comprising a top surface defining a top plane; a bottom surface defining a bottom plane; a connection portion including a hole with a center axis that intersects the top plane and the bottom plane; wherein a first portion of the edge of the hole is provided with a projection forming a first free end of the member and wherein a second portion of the edge of the hole is provided with a groove that is configured to accommodate a projection of a connection portion of a second member of the modular bone plate. Furthermore, a modular bone plate having at least two such members is provided.

Claims

1. A member of a modular bone plate, the member comprising:

a top surface defining a top plane;

a bottom surface defining a bottom plane; and

a connection portion defining a hole with a center axis that intersects the top plane and the bottom plane;

wherein a first part of the connection portion comprises a wall that extends around and faces away from the center axis of the hole, and a projection that extends away from the wall of the first part and forms a first free end of the member;

wherein a second part of the connection portion comprises a wall that is spaced apart from the hole and that extends around and faces towards the center axis of the hole, and wherein a groove is formed in the wall of the second part and extends away from the center axis of the hole to accommodate a projection of a connection portion of a second member of the modular bone plate; and

wherein a length of the groove in a circumferential direction corresponds substantially to a length of the projection in a circumferential direction.

2. A member of a modular bone plate, the member comprising:

a top surface defining a top plane;

a bottom surface defining a bottom plane;

a connection portion defining a hole with a center axis that intersects the top plane and the bottom plane, wherein a first part of the connection portion comprises a wall that extends around and faces away from the center axis of the hole, and a projection that extends away from the wall of the first part and forms a first free end of the member, wherein a second part of the connection portion comprises a wall that is spaced apart from the hole and that extends around and faces towards the center axis of the hole, and wherein a groove is formed in the wall of the second part and extends away from the center axis of the hole to accommodate a projection of a connection portion of a second member of the modular bone plate; and

a second connection portion defining a second hole with a center axis that intersects the top plane and the bottom plane, wherein a first part of the second connection portion comprises a wall that extends around and faces away from the center axis of the second hole, and a projection that extends away from the wall of the first part of the second connection portion and forms a second free end of the member opposite to the first free end, and wherein a second part of the second connection portion comprises a wall that is spaced apart from the second hole and that extends around and faces towards the center axis of the second hole, and wherein a groove is formed in the wall of the second part of the second connection portion and extends away from the center axis of the second hole to accommodate a projection of a connection portion of the second member of the modular bone plate.

3. A modular bone plate comprising:

a first member comprising a top surface defining a top plane, a bottom surface defining a bottom plane, and a connection portion defining a hole with a center axis that intersects the top plane and the bottom plane, wherein a first part of the connection portion of the first member comprises a wall that extends around and faces away from the center axis of the hole, and a projection that extends away from the wall of the first part of the first member and forms a first free end of the member, wherein a second part of the connection portion of the first member comprises a wall that is spaced apart from the hole and that extends around and faces towards the center axis of the hole, and wherein a groove is formed in the wall of the second part of the first member and extends away from the center axis of the hole to accommodate a projection of a connection portion of a second member of the modular bone plate; and

the second member comprising a top surface defining a top plane and a bottom surface defining a bottom plane, wherein the connection portion of the second member defines a second hole with a center axis that intersects the top and bottom planes of the second member, wherein a first part of the connection portion of the second member comprises a wall that extends around and faces away from the center axis of the second hole, wherein the projection of the second member extends away from the wall of the first part of the second member to form a first free end of the second member, wherein a second part of the connection portion of the second member comprises a wall that is spaced apart from the second hole and that extends around and faces towards the center axis of the second hole, and wherein a groove is formed in the wall of the second part of the second member and extends away from the center axis of the second hole to accommodate the projection of the connection portion of the first member;

wherein the first member is configured to be coupled to the second member when the projection of the first member is inserted into the groove of the second member and the projection of the second member is inserted into the groove of the first member; and

wherein the first member and the second member are configured to pivot relative to one another when the first member is coupled to the second member.
