Abstract

A modular bone plate is provided including at least a first and a second member each having a top surface and a bottom surface, the first member comprising a male connection portion with a single hole extending from the top surface to the bottom surface and the second member comprising a female connection portion with a single hole extending from the top surface to the bottom surface, wherein the male connection portion is insertable into the female connection portion such that the holes overlap and wherein an anchor or a plug member is insertable into the holes when they overlap.

Claims

1-21. -21. (canceled)

22. A connector piece of a modular bone plate comprising:

a first part having a male connection portion, a top surface, and a bottom surface, wherein the male connection portion has a single hole extending from the top surface of the first part to the bottom surface of the first part; and

a second part integrally connected to the first part and having a top surface, a bottom surface, and a female connection portion having a side wall extending between the top and bottom surfaces, the side wall having an inner surface, an outer surface, and a recess that extends through the side wall from the outer surface to the inner surface and that separates at least part of the female connection portion into an upper region and a lower region, the second part further having a single hole extending from the top surface of the second part to the bottom surface of the second part and through both the upper region and the lower region.

23. The connector piece according to claim 22, wherein the single holes of the male connection portion and the female connection portion vary in size.

24. The connector piece according to claim 22, wherein the holes are closed in a circumferential direction.

25. The connector piece according to claim 22, wherein the hole of at least one of the female connection portion or the male connection portion is threaded.

26. The connector piece according to claim 25, further comprising:

an anchor comprising a head with a spherical segment and a shaft; and

a cap to be screwed into the hole that is threaded.

27. The connector piece according to claim 25, further comprising:

a plug member configured to be connected to the hole of the female connection portion.

28. The connector piece according to claim 27, wherein the hole of the female connection portion is threaded, and wherein the plug member is configured to be screwed into the threaded hole of the female connection portion.

29. The connector piece according to claim 22, wherein the connector piece and the second connector piece are configured to be fixed relative to one another at an angle.

30. The connector piece according to claim 22, wherein the recess of the female connection portion communicates with the hole of the female connection portion.

31. The connector piece according to claim 22, wherein the male connection portion is formed by a tongue portion or a projection portion.

32. The connector piece according to claim 22, wherein the first part and the second part are connected to one another by a middle part.

33. The connector piece according to claim 32, wherein the middle part is an inclined portion so that the connector piece has a cascaded form.

34. The connector piece according to claim 22, wherein the female connection portion is substantially cylindrical, and wherein the recess extends circumferentially around about half of the side wall of the female connection portion.

35. The connector piece according to claim 22, wherein the male connection portion is cylindrical and has an extension to one side of the cylinder that is adapted to a contour of the side wall that defines the recess of the female connection portion.

36. The connector piece according to claim 22, wherein the recess defined by the female connection portion has a circular portion and two straight portions forming an angled configuration in a plane parallel to a top or bottom surface of the modular bone plate.

37. The connector piece according to claim 22, wherein the connector piece as a whole decreases in thickness from one side towards an opposite side.

38. The connector piece according to claim 22, wherein the connector piece decreases in thickness from a center towards either side.

39. The connector piece according to claim 22, wherein the male connection portion is insertable into a female connection portion of a second connector piece.

40. A modular bone plate assembly comprising:

a first connector piece including

a first part having a male connection portion, a top surface, and a bottom surface, wherein the male connection portion has a single hole extending from the top surface of the first part to the bottom surface of the first part; and

a second part integrally connected to the first part and having a top surface, a bottom surface, and a female connection portion having a side wall extending between the top and bottom surfaces, the side wall having an inner surface, an outer surface, and a recess that extends through the side wall from the outer surface to the inner surface and that separates at least part of the female connection portion into an upper region and a lower region, the second part further having a single hole extending from the top surface of the second part to the bottom surface of the second part and through both the upper region and the lower region; and

a second connector piece having a male connection portion and a female connection portion having a single hole therein,

wherein the male connection portion of the first part of the first connector piece is insertable into the female connection portion of the second connector piece such that the respective single holes of the male and female connection portions overlap with one another.

41. A connector piece of a modular bone plate comprising:

a first part having a male connection portion, a top surface, and a bottom surface, wherein the male connection portion has a single hole extending from the top surface of the first part to the bottom surface of the first part; and

a second part integrally connected to the first part and having a top surface, a bottom surface, and a female connection portion having a side wall extending between the top and bottom surfaces, the side wall having an inner surface, an outer surface, and a recess that extends through the side wall from the outer surface to the inner surface and that separates at least part of the female connection portion into an upper region and a lower region, the second part further having a single hole extending from the top surface of the second part to the bottom surface of the second part and through both the upper region and the lower region,

wherein the second part comprises a head of a modular humerus plate or a modular T-plate.

42. The connector piece according to claim 41, wherein the male connection portion is insertable into a female connection portion of a second connector piece.
