Abstract

A bone plate system and method for implanting the bone plate. The bone plate may include a head portion and a shaft portion, the shaft portion having a longitudinal axis and comprising a plurality of discrete aperture clusters. Each aperture cluster may include a non-threaded, non-locking bone fastener aperture configured to provide a polyaxial compressive construct and at least one threaded, locking bone fastener aperture. Once aligned with the bone, a first bone fastener is inserted into the bone through at least one of the non-threaded apertures in a direction normal to the longitudinal axis, compressing the bone along the longitudinal axis of the shaft portion of the bone plate. A second bone fastener is inserted into the bone through at least one of the threaded, locking bone fastener apertures in a direction oblique to the longitudinal axis and securing the bone plate to the bone.

First claim

What is claimed is:

1. A disposable single indication orthopedic trauma surgical system, comprising:
a sterile sealed container;
a single bone plate disposed in the sterile sealed container, the single bone plate being precontoured and sized to match an anatomic shape of a portion of a bone of a patient's extremity, the single bone plate including a head portion and a shaft portion having a longitudinal axis, the head portion being wider than the shaft portion, the single bone plate including a plurality of threaded, locking bone fastener apertures defined in the shaft portion and defining a respective plurality of threaded aperture axes, the single bone plate further including a plurality of non-threaded, non-locking bone fastener apertures defined in the shaft portion, aligned on the longitudinal axis, and defining a respective plurality of non-threaded aperture axes, each non-threaded aperture axis being angled between about ten degrees and about thirty degrees with respect to each threaded aperture axis;
a plurality of fasteners disposed in the sterile sealed container, each comprising a head and a shaft, the heads being dimensioned to mate with the threaded, locking bone fastener apertures and the non-threaded non-locking bone fastener apertures; and
a disposable torque driver disposed in the sterile sealed container and configured to engage the fastener heads.

2. The surgical system of claim 1 , wherein the portion of the bone is selected from the group consisting of the right distal volar radius, the left distal volar radius, the right fibula, the left fibula, the right proximal radius, the left proximal radius, the right navicular, the left navicular, the right distal ulna, and the left distal ulna.

3. The surgical system of claim 1 , wherein all of the fasteners in the surgical system consisting of fasteners having the same sized head.

4. The surgical system of claim 3 , wherein each of the plurality of threaded, locking bone fastener apertures and each of the plurality of non-threaded, non-locking bone fastener apertures are dimensioned to receive the same sized head of the plurality of fasteners.

5. The surgical system of claim 1 , wherein all of the fasteners in the surgical system consisting of fasteners having either a first sized head or a second sized head.

6. The surgical system of claim 5 , wherein all of the fastener apertures of the single bone plate are dimensioned to receive either the first sized head or the second sized head.

7. The surgical system of claim 1 , wherein all of the fasteners in the surgical system have only one of two different sized heads.

8. The surgical system of claim 1 , further comprising a wire drill, a drill guide, and a depth gage, all contained in the sterile sealed container.

9. The surgical system of claim 1 , wherein the plurality of fasteners comprises 36 or fewer fasteners.

10. The surgical system of claim 9 , wherein all of the fasteners in the surgical system have only one of nine or fewer different shaft lengths.

11. The surgical system of claim 1 , wherein the plurality of fasteners are arranged in the sterile sealed container in a plurality of groupings of four or fewer of the fasteners, the four or fewer fasteners in a respective grouping having the same shaft length.

12. The surgical system of claim 11 , wherein the sterile sealed container includes labels to indicate the shaft length of each of the plurality of groupings of fasteners.

13. The surgical system of claim 1 , wherein the sterile sealed container includes a plurality of fastener length gages to aid the user in determining the length of each of the plurality of fasteners.

14. The surgical system of claim 1 , wherein the system is resterilizable by a steam autoclave once the sterile sealed container has been opened.

15. A disposable single indication orthopedic trauma surgical system, comprising:
a sterile sealed container;
a single bone plate disposed in the sterile sealed container, the single bone plate being adapted for a use on a bone of a patient's extremity, the single bone plate including a head portion and a shaft portion having a longitudinal axis, the head portion being wider than the shaft portion, the single bone plate including a plurality of threaded, locking bone fastener holes defined in the shaft portion and defining a respective plurality of threaded hole axes, the single bone plate further including a plurality of non-threaded, non-locking bone fastener holes defined in the shaft portion, aligned on the longitudinal axis, and defining a respective plurality of non-threaded hole axes, each non-threaded hole axis being angled between about ten degrees and about thirty degrees with respect to each threaded hole axis;
a plurality of fasteners disposed in the sterile sealed container, each comprising a head and a shaft, the heads being adapted to interface with the threaded, locking bone fastener holes and the non-threaded, non-locking bone fastener holes;
a disposable torque driver disposed in the sterile sealed container and adapted to engage the fastener heads;
one or more wire drills disposed in the sterile sealed container;
one or more drill guides disposed in the sterile sealed container; and
a disposable depth gage disposed in the sterile sealed container.

16. The surgical system of claim 15 , wherein each of the plurality of threaded, locking bone fastener holes and each of the plurality of non-threaded, non-locking bone fastener holes of the single bone plate are dimensioned to receive the same sized head of the plurality of fasteners.

17. The surgical system of claim 15 , wherein the plurality of fasteners are arranged in the container in a plurality of groupings of the fasteners, a first one of the plurality of groupings including only fasteners having a first shaft length, a second one of the plurality of groupings including only fasteners having a second shaft length that is different from the first shaft length, the fasteners in the first one of the plurality of groupings being segregated from the fasteners in the second one of the plurality of groupings.

18. The surgical system of claim 17 , wherein the sterile sealed container includes labels to indicate the shaft length of the fasteners in each of the plurality of groupings of the fasteners.

19. The surgical system of claim 17 , wherein the container includes a plurality of fastener length gages to aid a user in determining the shaft length of each of the plurality of fasteners.

20. A disposable single indication orthopedic trauma surgical system, comprising:
a sterile sealed container;
a single bone plate disposed in the sterile sealed container, the single bone plate being precontoured and sized to match an anatomic shape of a portion of a bone of a patient's extremity, the single bone plate including a head portion and a shaft portion having a longitudinal axis, the head portion being wider than the shaft portion, the single bone plate including a plurality of threaded, locking bone fastener apertures defined in the shaft portion and defining a respective plurality of threaded aperture axes, the single bone plate further including a plurality of non-threaded, non-locking bone fastener apertures defined in the shaft portion, aligned on the longitudinal axis, and defining a respective plurality of non-threaded aperture axes, each non-threaded aperture axis being angled between about ten degrees and about thirty degrees with respect to each threaded aperture axis;
a plurality of fasteners disposed in the sterile sea
