Abstract

The presently disclosed and claimed inventive concept(s) relates generally to the field of bone plates for the reduction and fixation of bone fractures, in particular, the presently disclosed and claimed inventive concept(s) relates to a quadrilateral surface bone plate for the fixation of acetabular fractures having at least one securing port therein and methods of making and using same.

First claim

What I claim is:

1. A bone plating system for a patient, comprising:
a first bone plate sized and shaped to conform to a first bone portion of the patient, wherein the first bone plate is a suprapectineal plate;
a second bone plate sized and shaped to conform to a second bone portion of the patient, the second bone plate having a proximal end and a distal end, wherein the second bone plate includes a securing port having a central axis extending through and at an angle relative to a tissue engaging surface and a bone engaging surface of the second bone plate in a direction oriented towards the distal end of the second bone plate, the securing port configured to receive a fastener at an angle less than about 90 degrees with respect to the tissue engaging surface of the second bone plate, wherein the second bone plate is a quadrilateral plate, and wherein the securing port further comprises a bore extending from the tissue engaging surface of the second bone plate to the bone engaging surface of the second bone plate, the bore extending in a direction substantially oriented toward the distal end of the second bone plate and away from the proximal end of the second bone plate, and wherein the securing port further comprises a wall surrounding the bore, wherein the wall defines (i) a fastener support surface defining a head receiving volume adjacent the tissue engaging surface, and (ii) a shaft clearance surface defining a generally frustoconical shaped shaft receiving volume; and
at least one connecting bridge member configured to attach the first bone plate to the proximal end of the second bone plate.

2. The bone plating system of claim 1 , wherein the suprapectineal plate is sized and shaped to conform to a pelvic brim of the patient and the quadrilateral plate is sized and shaped to a quadrilateral surface of the patient.

3. The bone plating system of claim 1 , wherein the first bone plate has a first edge, a second edge, a first end, and a second end with a width extending generally between the first edge and the second edge, and a length extending between the first end and the second end, the length being greater than the width.

4. The bone plating system of claim 3 , wherein the first end and second end of the first bone plate are generally rounded having a convex shape extending generally from a bone engaging surface to a tissue engaging surface of the first bone plate.

5. The bone plating system of claim 3 , wherein the length of the first bone plate is defined as having one or more curves or twists that conform the first bone plate to an anatomy of the patient.

6. The bone plating system of claim 1 , wherein the first bone plate further comprises a plurality of screw apertures.

7. The bone plating system of claim 6 , wherein the plurality of screw apertures further include a screw head support surface and a screw shaft clearance surface, with the screw head support surface defining a screw head receiving volume and the screw shaft clearance surface defining a screw shaft receiving volume.

8. The bone plating system of claim 7 , wherein the first bone plate further comprises a plurality of forming bridges adjacent and between the plurality of screw apertures.

9. The bone plating system of claim 8 , wherein the plurality of forming bridges are plastically deformable thereby providing the first bone plate with a secondary configuration.

10. The bone plating system of claim 9 , wherein the secondary configuration of the first bone plate matches an anatomy of the patient.

11. The bone plating system of claim 1 , wherein the second bone plate is generally trapezoid shaped and further includes a first side, and a second side wherein the distal end and the proximal end are generally parallel to one another and the first side and the second side generally diverge from one another.

12. The bone plating system of claim 11 , wherein the second bone plate further comprises a plurality of secondary screw apertures.

13. The bone plating system of claim 12 , wherein the plurality of secondary screw apertures further include a screw head support surface and a screw shaft clearance surface, with the screw head support surface defining a screw head receiving volume and the screw shaft clearance surface defining a screw shaft receiving volume.

14. The bone plating system of claim 11 , wherein the second bone plate is defined by a plurality of internal struts defining a plurality of through-holes extending from the bone engaging surface to the tissue engaging surface of the second bone plate.

15. The bone plating system of claim 1 , wherein the second bone plate further includes at least one reduction engaging aperture for receiving a surgical instrument capable of applying a force to the second bone plate.

16. The bone plating system of claim 1 , wherein the bore further comprises a bore central axis extending through a center of the bore in a direction substantially oriented toward the distal end of the second bone plate and away from the proximal end of the second bone plate.

17. The bone plating system of claim 16 , wherein the head receiving volume of the fastener support surface of the securing port is generally spherically shaped, and the shaft clearance surface of the securing port is generally ellipse shaped.

18. The bone plating system of claim 17 , wherein the fastener support surface is adjacent and abuts the shaft clearance surface at a bore vertex extending generally an entire circumference of the bore.

19. The bone plating system of claim 18 , wherein the securing port further comprises a fastener support axis generally adjacent the bore vertex, wherein the fastener support axis extends at a first angle that is less than or equal to 90 degrees relative to a bone engaging axis of the second bone plate.
