Abstract

A bone implant made form a spongiform and/or cortical bone material of human or animal origin, comprises at least one surface region with several longitudinal adjacent drillings which do not extend through the bone implant.

Claims

1. A bone implant of spongious and/or cortical bone material of human or animal origin,

in which at least one surface region (12:

26. 30) of the bone implant (10) has a plurality of elongate bores (14;

28, 32) arranged adjacently and not passing through the bone implant characterized in that

the surface region (12;

26) with bores (14;

28) extends up to a edge of the bone implant, with the bores (20) in the edge region being outwardly open and thereby forming a ribbed section (22, 24).

2. A bone implant in accordance with claim 1, characterized in that the bores (14;

28, 34) are arranged in a matrix shape.

3. A bone implant in accordance with claim 1, characterized in that the surface region with the bores (12;

26) forms a membrane section (14;

28).

4. A bone implant in accordance with claim 1, characterized in that the maximum width of the bores (14;

28) lies between approximately 0.05 mm and approximately 2 mm.

5. A bone implant in accordance with claim 1, characterized in that the depth of the bores (14;

28) lies between approximately 0.1 mm and approximately 10 mm.

6. A bone implant in accordance with claim 1, characterized in that the spacing of adjacent bores (14;

28) is not larger than twice their maximum width.

7. A bone implant in accordance with claim 1, characterized in that the surface region (12;

26) has between approximately 20 and 200 bores (14;

28) per cm².

8. A bone implant in accordance with claim 4, characterized in that the spacing of the bores (14;

28) lies between 0.01 mm and the maximum width of the bores.

9. A bone implant in accordance with claim 5, characterized in that the axes of the bores (14;

28) are aligned substantially parallel.

10. A bone implant in accordance with claim 1, characterized in that the bone material between the bores (14) is compact.

11. A bone implant in accordance with claim 1, characterized in that the bone implant has a further surface region (30) into which further bores (32) have been introduced which each at least partly intersect at least one of the bores (28) in the surface region (26).

12. A bone implant in accordance with claim 11, characterized in that at least one of the further bores (32) in the further surface region (30) at least partly intersects at least one of the bores (28) in the surface region (26) at an angle of approximately 90°

.

13. A bone implant in accordance with claim 11, characterized in that at least some of the further bores (32) and some of the bores (28) intersecting them in the surface region (26) are formed such that they form a grid of mutually connected bore passages (34, 36).

14. A bone implant in accordance with claim 1, characterized in that the material of the bone implant consists of preserved and sterile bone material.
