Abstract

The current invention comprises a bone plate and method of use contoured to fit above the medial epicondyle that provides numerous apertures for fixation to the distal femur as desired with an offset screw design in shaft to allow location of screws around a nail or other feature and may also allow for attachment in conjunction with a lateral distal plate and or an extension plate that may cover the medial condyle.

Claims (27)

1. A method for internal fixation of fractures and non-unions of a distal femur comprising:

contacting a distal end of a medial distal femur plate with a medial condyle of a femur;

contacting a proximal end of the medial distal femur plate with the medial femur shaft;

inserting a plurality of bone anchors through the medial distal femur plate and into a medial side of the femur such that the medial distal femur plate is secured to the femur exclusively by the plurality of bone anchors, wherein the step of inserting a plurality of bone anchors includes inserting at least one first bone anchor through a first aperture formed through the distal end of the medial distal femur plate and into a medial side of the femur, and inserting at least one second bone anchor through a second aperture formed through the proximal end of the medial distal femur plate and into the medial side of the femur.

2. A method for internal fixation of fractures and non-unions of a distal femur comprising:

contacting a distal end of a medial distal femur plate with a medial condyle of a femur;

contacting a proximal end of the medial distal femur plate with the medial femur shaft;

inserting at least one first bone anchor through a first aperture formed through the distal end of the medial distal femur plate and into a medial side of the femur; and

inserting at least one second bone anchor through a second aperture formed through the proximal end of the medial distal femur plate and into the medial side of the femur,

wherein the distal end is wider than the proximal end and includes a first and a second flared portion, the first flared portion extending distally and anteriorly and the second flared portion extending distally and posteriorly such that the distal end conforms to a curvature of the medial condyle.

3. The method according to claim 2 , wherein the step of contacting the distal end includes contacting the distal end of the medial distal femur plate to a magnus tubercle of the medial condyle.

4. The method according to claim 2 , wherein the distal end is concave between the first and second flared portions.

5. The method according to claim 2 , wherein a body of the medial distal femur plate is disposed between the proximal and the distal ends, the distal end extending medially and distally away from the body such that the distal end and the body define a curve conforming to the concave curvature of a medial surface of the distal femur.

6. The method according to claim 5 , wherein the curve is less than or equal to 20 degrees.

7. The method according to claim 5 , wherein the curve is more than 20 degrees.

8. The method according to claim 2 , wherein at least one first bone anchor extends from the medial condyle into the lateral condyle such that a distal end of the first bone anchor is disposed within the lateral condyle.

9. The method according to claim 2 , further comprising the step of attaching a lateral plate to a lateral side of the distal femur.

10. The method according to claim 2 , wherein a length of the medial distal femur plate is at least 15 centimeters.

11. The method according to claim 2 , wherein a length of the medial distal femur plate is less than 15 centimeters.

12. The method according to claim 2 , where the medial distal femur plate is made from titanium.

13. The method according to claim 2 , wherein the medial distal femur plate is made from stainless steel.

14. The method according to claim 2 , wherein the top surface is at a distance of at least 5 millimeters from the bone contacting surface.

15. The method according to claim 2 , wherein the top surface is at a distance of less than 5 millimeters from the bone contacting surface.

16. The method according to claim 2 , wherein the distal end has a width of at least 35 millimeters.

17. The method according to claim 2 , wherein the distal end has a width less than 35 millimeters.

18. The method according to claim 2 , wherein the proximal end has a width of at least 18 millimeters.

19. The method according to claim 2 , wherein the proximal end has a width of less than 18 millimeters.
