Implant for stabilizing fractured or non-fractured bones, use of an implant and method for stabilizing fractured or non-fractured bones
A bone implant ( 1 ) for stabilizing fractured or non-fractured bones comprises an implant body ( 2 ), preferably a cylindrical body, extending along a longitudinal axis ( 3 ) from a front side ( 4 ) to an end side ( 5 ). The implant has an implant width ( 6 ) extending perpendicularly to the longitudinal axis ( 3 ), and a length of the implant body ( 2 ) along the longitudinal axis ( 3 ) is at least 5 times the width ( 6 ) of the implant. The implant body ( 2 ) has an outer surface, being at least divided into a first surface ( 7 ) and a second surface ( 8 . The first surface ( 7 ) comprises an anchorage area ( 9 ) which extends at least partially over the outer surface, preferably maximum over half of the outer surface.
1. A bone implant for stabilizing fractured or non-fractured bones, said implant comprising:
an implant body extending along a longitudinal axis, from a front side to an end side, and having an implant width extending perpendicularly to the longitudinal axis,
wherein a length of said implant body along said longitudinal axis is at least 5 times said implant width,
said implant body has an outer surface which is divided at least into a first surface and a second surface, and
said first surface comprises an anchorage area which extends at least partially over said outer surface but no greater than half of the outer surface,
the implant does not have any widening at a proximal end thereof,
holes are substantially equally distributed 360° around at least one of the outer surface or the second surface, the distributed holes form longitudinal rows of holes which extend along the longitudinal axis of the implant body such that a spacing between adjacent holes, located within the longitudinal row of holes, is substantially the same, wherein said holes are not connected by a groove.
2. The bone implant according to claim 1 , wherein the implant comprises a bore extending along said longitudinal axis or parallel to said longitudinal axis having at least one opening at said front side and/or at said end side.
3. The bone implant according to claim 1 , wherein the length of the bone implant is in a range from 10 mm to 250 mm.
4. The bone implant according to claim 1 , wherein the width of the bone implant is in a range from 2 mm to 10 mm.
5. The bone implant according to claim 1 , wherein said outer surface comprises holes having a wall around a hole axis.
6. The bone implant according to claim 5 , wherein the implant (1) comprises a first set of holes, and said hole axis of said first set of holes is arranged substantially perpendicular to said longitudinal axis.
7. The bone implant according to claim 5 , wherein the implant comprises a second set of holes, and said hole axis of said second set of holes is inclined relative to said longitudinal axis.
8. The bone implant according to claim 1 , wherein said anchorage area comprises fixation improvement structure.
9. The bone implant according to claim 1 , wherein said anchorage area comprises surface structures in a form of grooves, distributed substantially equally around said longitudinal axis, extending coaxially along said longitudinal axis.
10. The bone implant according to claim 1 , wherein the anchorage area comprises surface structures in a form of thread or ring shaped grooves.
11. A method of stabilizing a fractured or non-fractured bone by inserting a bone implant according to claim 1 into bone.
12. A bone implant for stabilizing fractured or non-fractured bones, said implant comprising:
an implant body extending along a longitudinal axis, from a front side to an end side, and having an implant width extending perpendicularly to the longitudinal axis,
wherein a length of said implant body along said longitudinal axis is at least 5 times said implant width,
said implant body has an outer surface which is divided at least into a first surface and a second surface, and
said first surface comprising an anchorage area which extends at least partially over said outer surface
the implant body has a constant width over at least the first and the second surfaces without any widening at a proximal end of the implant,
holes are substantially equally distributed 360° around at least one of the outer surface or the second surface, the distributed holes form longitudinal rows of holes which extend along the longitudinal axis of the implant body such that a spacing between adjacent holes, located within the longitudinal row of holes, is substantially the same.
